OpenID Connect authorization code flow mechanism for protecting web applications
To protect your web applications, you can use the industry-standard OpenID Connect (OIDC) Authorization Code Flow mechanism provided by the Quarkus OIDC extension.
Overview of the OIDC authorization code flow mechanism
The Quarkus OpenID Connect (OIDC) extension can protect application HTTP endpoints by using the OIDC Authorization Code Flow mechanism supported by OIDC-compliant authorization servers, such as Keycloak.
The Authorization Code Flow mechanism authenticates users of your web application by redirecting them to an OIDC provider, such as Keycloak, to log in. After authentication, the OIDC provider redirects the user back to the application with an authorization code that confirms that authentication was successful. Then, the application exchanges this code with the OIDC provider for an ID token (which represents the authenticated user), an access token, and a refresh token to authorize the user’s access to the application.
The following diagram outlines the Authorization Code Flow mechanism in Quarkus.
-
The Quarkus user requests access to a Quarkus
web-appapplication. -
The Quarkus web-app redirects the user to the authorization endpoint, that is, the OIDC provider for authentication.
-
The OIDC provider redirects the user to a login and authentication prompt.
-
At the prompt, the user enters their user credentials.
-
The OIDC provider authenticates the user credentials entered and, if successful, issues an authorization code and redirects the user back to the Quarkus web-app with the code included as a query parameter.
-
The Quarkus web-app exchanges this authorization code with the OIDC provider for ID, access, and refresh tokens.
The authorization code flow is completed and the Quarkus web-app uses the tokens issued to access information about the user and grants the relevant role-based authorization to that user. The following tokens are issued:
-
ID token: The Quarkus
web-appapplication uses the user information in the ID token to enable the authenticated user to log in securely and to provide role-based access to the web application. -
Access token: The Quarkus web-app might use the access token to access the UserInfo API to get additional information about the authenticated user or to propagate it to another endpoint.
-
Refresh token: (Optional) If the ID and access tokens expire, the Quarkus web-app can use the refresh token to get new ID and access tokens.

Using the authorization code flow mechanism
Configuring access to the OIDC provider endpoint
The OIDC web-app application requires URLs of the OIDC provider’s authorization, token, JsonWebKey (JWK) set, and possibly the UserInfo, introspection and end-session (RP-initiated logout) endpoints.
By convention, they are discovered by adding a /.well-known/openid-configuration path to the configured quarkus.oidc.auth-server-url.
Alternatively, if the discovery endpoint is not available, or you prefer to reduce the discovery endpoint round-trip, you can disable endpoint discovery and configure relative path values. For example:
quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus
quarkus.oidc.discovery-enabled=false
# Authorization endpoint: http://localhost:8180/realms/quarkus/protocol/openid-connect/auth
quarkus.oidc.authorization-path=/protocol/openid-connect/auth
# Token endpoint: http://localhost:8180/realms/quarkus/protocol/openid-connect/token
quarkus.oidc.token-path=/protocol/openid-connect/token
# JWK set endpoint: http://localhost:8180/realms/quarkus/protocol/openid-connect/certs
quarkus.oidc.jwks-path=/protocol/openid-connect/certs
# UserInfo endpoint: http://localhost:8180/realms/quarkus/protocol/openid-connect/userinfo
quarkus.oidc.user-info-path=/protocol/openid-connect/userinfo
# Token Introspection endpoint: http://localhost:8180/realms/quarkus/protocol/openid-connect/token/introspect
quarkus.oidc.introspection-path=/protocol/openid-connect/token/introspect
# End-session endpoint: http://localhost:8180/realms/quarkus/protocol/openid-connect/logout
quarkus.oidc.end-session-path=/protocol/openid-connect/logoutSome OIDC providers support metadata discovery but do not return all the endpoint URL values required for the authorization code flow to complete or to support application functions, for example, user logout. To work around this limitation, you can configure the missing endpoint URL values locally, as outlined in the following example:
# Metadata is auto-discovered but it does not return an end-session endpoint URL
quarkus.oidc.auth-server-url=http://localhost:8180/oidcprovider/account
# Configure the end-session URL locally.
# It can be an absolute or relative (to 'quarkus.oidc.auth-server-url') address
quarkus.oidc.end-session-path=logoutYou can use this same configuration to override a discovered endpoint URL if that URL does not work for the local Quarkus endpoint and a more specific value is required.
For example, a provider that supports both global and application-specific end-session endpoints returns a global end-session URL such as http://localhost:8180/oidcprovider/account/global-logout.
This URL will log the user out of all the applications into which the user is currently logged in.
However, if the requirement is for the current application to log the user out of a specific application only, you can override the global end-session URL, by setting the quarkus.oidc.end-session-path=logout parameter.
OIDC provider client authentication
OIDC providers typically require applications to be identified and authenticated when they interact with the OIDC endpoints.
Quarkus OIDC, specifically the quarkus.oidc.runtime.OidcProviderClient class, authenticates to the OIDC provider when the authorization code must be exchanged for the ID, access, and refresh tokens, or when the ID and access tokens must be refreshed or introspected.
Typically, client id and client secrets are defined for a given application when it enlists to the OIDC provider. All OIDC client authentication options are supported. For example:
client_secret_basic:quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus/
quarkus.oidc.client-id=quarkus-app
quarkus.oidc.credentials.secret=mysecretOr:
quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus/
quarkus.oidc.client-id=quarkus-app
quarkus.oidc.credentials.client-secret.value=mysecretThe following example shows the secret retrieved from a credentials provider:
quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus/
quarkus.oidc.client-id=quarkus-app
# This is a key which will be used to retrieve a secret from the map of credentials returned from CredentialsProvider
quarkus.oidc.credentials.client-secret.provider.key=mysecret-key
# Set it only if more than one CredentialsProvider can be registered
quarkus.oidc.credentials.client-secret.provider.name=oidc-credentials-providerclient_secret_postquarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus/
quarkus.oidc.client-id=quarkus-app
quarkus.oidc.credentials.client-secret.value=mysecret
quarkus.oidc.credentials.client-secret.method=postclient_secret_jwt, where the signature algorithm is HS256:quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus/
quarkus.oidc.client-id=quarkus-app
quarkus.oidc.credentials.jwt.secret=AyM1SysPpbyDfgZld3umj1qzKObwVMkoqQ-EstJQLr_T-1qS0gZH75aKtMN3Yj0iPS4hcgUuTwjAzZr1Z9CAowclient_secret_jwt, where the secret is retrieved from a credentials provider:quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus/
quarkus.oidc.client-id=quarkus-app
# This is a key which will be used to retrieve a secret from the map of credentials returned from CredentialsProvider
quarkus.oidc.credentials.jwt.secret-provider.key=mysecret-key
# Set it only if more than one CredentialsProvider can be registered
quarkus.oidc.credentials.jwt.secret-provider.name=oidc-credentials-providerExample of private_key_jwt with the PEM key file, and where the signature algorithm is RS256:
quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus/
quarkus.oidc.client-id=quarkus-app
quarkus.oidc.credentials.jwt.key-file=privateKey.pemprivate_key_jwt with the keystore file, where the signature algorithm is RS256:quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus/
quarkus.oidc.client-id=quarkus-app
quarkus.oidc.credentials.jwt.key-store-file=keystore.jks
quarkus.oidc.credentials.jwt.key-store-password=mypassword
quarkus.oidc.credentials.jwt.key-password=mykeypassword
# Private key alias inside the keystore
quarkus.oidc.credentials.jwt.key-id=mykeyAliasUsing client_secret_jwt or private_key_jwt authentication methods ensures that a client secret does not get sent to the OIDC provider, therefore avoiding the risk of a secret being intercepted by a 'man-in-the-middle' attack.
Additional JWT authentication options
If client_secret_jwt, private_key_jwt, or an Apple post_jwt authentication methods are used, then you can customize the JWT signature algorithm, key identifier, audience, subject and issuer.
For example:
# private_key_jwt client authentication
quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus/
quarkus.oidc.client-id=quarkus-app
quarkus.oidc.credentials.jwt.key-file=privateKey.pem
# This is a token key identifier 'kid' header - set it if your OIDC provider requires it:
# Note if the key is represented in a JSON Web Key (JWK) format with a `kid` property, then
# using 'quarkus.oidc.credentials.jwt.token-key-id' is not necessary.
quarkus.oidc.credentials.jwt.token-key-id=mykey
# Use RS512 signature algorithm instead of the default RS256
quarkus.oidc.credentials.jwt.signature-algorithm=RS512
# The token endpoint URL is the default audience value, use the base address URL instead:
quarkus.oidc.credentials.jwt.audience=${quarkus.oidc-client.auth-server-url}
# custom subject instead of the client id:
quarkus.oidc.credentials.jwt.subject=custom-subject
# custom issuer instead of the client id:
quarkus.oidc.credentials.jwt.issuer=custom-issuerApple POST JWT
The Apple OIDC provider uses a client_secret_post method whereby a secret is a JWT produced with a private_key_jwt authentication method, but with the Apple account-specific issuer and subject claims.
In Quarkus Security, quarkus-oidc supports a non-standard client_secret_post_jwt authentication method, which you can configure as follows:
# Apple provider configuration sets a 'client_secret_post_jwt' authentication method
quarkus.oidc.provider=apple
quarkus.oidc.client-id=${apple.client-id}
quarkus.oidc.credentials.jwt.key-file=ecPrivateKey.pem
quarkus.oidc.credentials.jwt.token-key-id=${apple.key-id}
# Apple provider configuration sets ES256 signature algorithm
quarkus.oidc.credentials.jwt.subject=${apple.subject}
quarkus.oidc.credentials.jwt.issuer=${apple.issuer}mutual TLS (mTLS)
Some OIDC providers might require that a client is authenticated as part of the mutual TLS authentication process.
The following example shows how you can configure quarkus-oidc to support mTLS:
quarkus.oidc.tls.verification=certificate-validation
# Keystore configuration
quarkus.oidc.tls.key-store-file=client-keystore.jks
quarkus.oidc.tls.key-store-password=${key-store-password}
# Add more keystore properties if needed:
#quarkus.oidc.tls.key-store-alias=keyAlias
#quarkus.oidc.tls.key-store-alias-password=keyAliasPassword
# Truststore configuration
quarkus.oidc.tls.trust-store-file=client-truststore.jks
quarkus.oidc.tls.trust-store-password=${trust-store-password}
# Add more truststore properties if needed:
#quarkus.oidc.tls.trust-store-alias=certAliasPOST query
Some providers, such as the Strava OAuth2 provider, require client credentials be posted as HTTP POST query parameters:
quarkus.oidc.provider=strava
quarkus.oidc.client-id=quarkus-app
quarkus.oidc.credentials.client-secret.value=mysecret
quarkus.oidc.credentials.client-secret.method=queryIntrospection endpoint authentication
Some OIDC providers require authentication to its introspection endpoint by using Basic authentication and with credentials that are different from the client_id and client_secret.
If you have previously configured security authentication to support either the client_secret_basic or client_secret_post client authentication methods as described in the OIDC provider client authentication section, you might need to apply the additional configuration as follows.
If the tokens have to be introspected and the introspection endpoint-specific authentication mechanism is required, you can configure quarkus-oidc as follows:
quarkus.oidc.introspection-credentials.name=introspection-user-name
quarkus.oidc.introspection-credentials.secret=introspection-user-secretOIDC request filters
You can filter OIDC requests made by Quarkus to the OIDC provider by registering one or more OidcRequestFilter implementations, which can update or add new request headers and can also log requests.
例如：
package io.quarkus.it.keycloak;
import jakarta.enterprise.context.ApplicationScoped;
import io.quarkus.arc.Unremovable;
import io.quarkus.oidc.common.OidcRequestContextProperties;
import io.quarkus.oidc.common.OidcRequestFilter;
import io.vertx.mutiny.core.buffer.Buffer;
import io.vertx.mutiny.ext.web.client.HttpRequest;
@ApplicationScoped
@Unremovable
public class OidcTokenRequestCustomizer implements OidcRequestFilter {
@Override
public void filter(HttpRequest<Buffer> request, Buffer buffer, OidcRequestContextProperties contextProps) {
OidcConfigurationMetadata metadata = contextProps.get(OidcConfigurationMetadata.class.getName()); (1)
// Metadata URI is absolute, request URI value is relative
if (metadata.getTokenUri().endsWith(request.uri())) { (2)
request.putHeader("TokenGrantDigest", calculateDigest(buffer.toString()));
}
}
private String calculateDigest(String bodyString) {
// Apply the required digest algorithm to the body string
}
}| 1 | Get OidcConfigurationMetadata, which contains all supported OIDC endpoint addresses. |
| 2 | Use OidcConfigurationMetadata to filter requests to the OIDC token endpoint only. |
Alternatively, you can use OidcRequestFilter.Endpoint enum to apply this filter to the token endpoint requests only:
import jakarta.enterprise.context.ApplicationScoped;
import io.quarkus.arc.Unremovable;
import io.quarkus.oidc.common.OidcEndpoint;
import io.quarkus.oidc.common.OidcEndpoint.Type;
import io.quarkus.oidc.common.OidcRequestContextProperties;
import io.quarkus.oidc.common.OidcRequestFilter;
import io.vertx.mutiny.core.buffer.Buffer;
import io.vertx.mutiny.ext.web.client.HttpRequest;
@ApplicationScoped
@Unremovable
@OidcEndpoint(value = Type.DISCOVERY) (1)
public class OidcDiscoveryRequestCustomizer implements OidcRequestFilter {
@Override
public void filter(HttpRequest<Buffer> request, Buffer buffer, OidcRequestContextProperties contextProps) {
request.putHeader("Discovery", "OK");
}
}| 1 | Restrict this filter to requests targeting the OIDC discovery endpoint only. |
Redirecting to and from the OIDC provider
When a user is redirected to the OIDC provider to authenticate, the redirect URL includes a redirect_uri query parameter, which indicates to the provider where the user has to be redirected to when the authentication is complete.
In our case, this is the Quarkus application.
Quarkus sets this parameter to the current application request URL by default.
For example, if a user is trying to access a Quarkus service endpoint at http://localhost:8080/service/1, then the redirect_uri parameter is set to http://localhost:8080/service/1.
Similarly, if the request URL is http://localhost:8080/service/2, then the redirect_uri parameter is set to http://localhost:8080/service/2.
Some OIDC providers require the redirect_uri to have the same value for a given application, for example, http://localhost:8080/service/callback, for all the redirect URLs.
In such cases, a quarkus.oidc.authentication.redirect-path property has to be set.
For example, quarkus.oidc.authentication.redirect-path=/service/callback, and Quarkus will set the redirect_uri parameter to an absolute URL such as http://localhost:8080/service/callback, which will be the same regardless of the current request URL.
If quarkus.oidc.authentication.redirect-path is set, but you need the original request URL to be restored after the user is redirected back to a unique callback URL, for example, http://localhost:8080/service/callback, set quarkus.oidc.authentication.restore-path-after-redirect property to true.
This will restore the request URL such as http://localhost:8080/service/1.
Customizing authentication requests
By default, only the response_type (set to code), scope (set to openid), client_id, redirect_uri, and state properties are passed as HTTP query parameters to the OIDC provider’s authorization endpoint when the user is redirected to it to authenticate.
You can add more properties to it with quarkus.oidc.authentication.extra-params.
For example, some OIDC providers might choose to return the authorization code as part of the redirect URI’s fragment, which would break the authentication process.
The following example shows how you can work around this issue:
quarkus.oidc.authentication.extra-params.response_mode=queryCustomizing the authentication error response
When the user is redirected to the OIDC authorization endpoint to authenticate and, if necessary, authorize the Quarkus application, this redirect request might fail, for example, when an invalid scope is included in the redirect URI.
In such cases, the provider redirects the user back to Quarkus with error and error_description parameters instead of the expected code parameter.
For example, this can happen when an invalid scope or other invalid parameters are included in the redirect to the provider.
In such cases, an HTTP 401 error is returned by default.
However, you can request that a custom public error endpoint be called to return a more user-friendly HTML error page.
To do this, set the quarkus.oidc.authentication.error-path property, as shown in the following example:
quarkus.oidc.authentication.error-path=/errorEnsure that the property starts with a forward slash (/) character and the path is relative to the base URI of the current endpoint.
For example, if it is set to '/error' and the current request URI is https://localhost:8080/callback?error=invalid_scope, then a final redirect is made to https://localhost:8080/error?error=invalid_scope.
|
To prevent the user from being redirected to this page to be re-authenticated, ensure that this error endpoint is a public resource. |
Accessing authorization data
You can access information about authorization in different ways.
Accessing ID and access tokens
The OIDC code authentication mechanism acquires three tokens during the authorization code flow: ID token, access token, and refresh token.
The ID token is always a JWT token and represents a user authentication with the JWT claims.
You can use this to get the issuing OIDC endpoint, the username, and other information called claims.
You can access ID token claims by injecting JsonWebToken with an IdToken qualifier:
import jakarta.inject.Inject;
import org.eclipse.microprofile.jwt.JsonWebToken;
import io.quarkus.oidc.IdToken;
import io.quarkus.security.Authenticated;
@Path("/web-app")
@Authenticated
public class ProtectedResource {
@Inject
@IdToken
JsonWebToken idToken;
@GET
public String getUserName() {
return idToken.getName();
}
}The OIDC web-app application usually uses the access token to access other endpoints on behalf of the currently logged-in user.
You can access the raw access token as follows:
import jakarta.inject.Inject;
import org.eclipse.microprofile.jwt.JsonWebToken;
import io.quarkus.oidc.AccessTokenCredential;
import io.quarkus.security.Authenticated;
@Path("/web-app")
@Authenticated
public class ProtectedResource {
@Inject
JsonWebToken accessToken;
// or
// @Inject
// AccessTokenCredential accessTokenCredential;
@GET
public String getReservationOnBehalfOfUser() {
String rawAccessToken = accessToken.getRawToken();
//or
//String rawAccessToken = accessTokenCredential.getToken();
// Use the raw access token to access a remote endpoint.
// For example, use RestClient to set this token as a `Bearer` scheme value of the HTTP `Authorization` header:
// `Authorization: Bearer rawAccessToken`.
return getReservationfromRemoteEndpoint(rawAccesstoken);
}
}|
|
Injection of the JsonWebToken and AccessTokenCredential is supported in both @RequestScoped and @ApplicationScoped contexts.
Quarkus OIDC uses the refresh token to refresh the current ID and access tokens as part of its session management process.
User info
If the ID token does not provide enough information about the currently authenticated user, you can get more information from the UserInfo endpoint.
Set the quarkus.oidc.authentication.user-info-required=true property to request a UserInfo JSON object from the OIDC UserInfo endpoint.
A request is sent to the OIDC provider UserInfo endpoint by using the access token returned with the authorization code grant response, and an io.quarkus.oidc.UserInfo (a simple jakarta.json.JsonObject wrapper) object is created.
io.quarkus.oidc.UserInfo can be injected or accessed as a SecurityIdentity userinfo attribute.
Accessing the OIDC configuration information
The current tenant’s discovered OpenID Connect configuration metadata is represented by io.quarkus.oidc.OidcConfigurationMetadata and can be injected or accessed as a SecurityIdentity configuration-metadata attribute.
如果端点是公开的，则默认租户的 OidcConfigurationMetadata 会被注入。
Mapping token claims and SecurityIdentity roles
The way the roles are mapped to the SecurityIdentity roles from the verified tokens is identical to how it is done for the Bearer tokens. The only difference is that ID token is used as a source of the roles by default.
|
If you use Keycloak, set a |
However, depending on your OIDC provider, roles might be stored in the access token or the user info.
If the access token contains the roles and this access token is not meant to be propagated to the downstream endpoints, then set quarkus.oidc.roles.source=accesstoken.
If UserInfo is the source of the roles, then set quarkus.oidc.roles.source=userinfo, and if needed, quarkus.oidc.roles.role-claim-path.
Additionally, you can also use a custom SecurityIdentityAugmentor to add the roles.
For more information, see SecurityIdentity customization.
You can also map SecurityIdentity roles created from token claims to deployment-specific roles with the HTTP Security policy.
Ensuring validity of tokens and authentication data
A core part of the authentication process is ensuring the chain of trust and validity of the information. This is done by ensuring tokens can be trusted.
Token verification and introspection
The verification process of OIDC authorization code flow tokens follows the Bearer token authentication token verification and introspection logic. For more information, see the Token verification and introspection section of the "Quarkus OpenID Connect (OIDC) Bearer token authentication" guide.

With Quarkus |
Token introspection and UserInfo cache
Code flow access tokens are not introspected unless they are expected to be the source of roles.
However, they will be used to get UserInfo.
There will be one or two remote calls with the code flow access token if the token introspection, UserInfo, or both are required.
For more information about using the default token cache or registering a custom cache implementation, see Token introspection and UserInfo cache.
JSON web token claim verification
For information about the claim verification, including the iss (issuer) claim, see the JSON Web Token claim verification section.
It applies to ID tokens and also to access tokens in a JWT format, if the web-app application has requested the access token verification.
Further security with Proof Key for Code Exchange (PKCE)
Proof Key for Code Exchange (PKCE) minimizes the risk of authorization code interception.
While PKCE is of primary importance to public OIDC clients, such as SPA scripts running in a browser, it can also provide extra protection to Quarkus OIDC web-app applications.
With PKCE, Quarkus OIDC web-app applications act as confidential OIDC clients that can securely store the client secret and use it to exchange the code for the tokens.
You can enable PKCE for your OIDC web-app endpoint with a quarkus.oidc.authentication.pkce-required property and a 32-character secret that is required to encrypt the PKCE code verifier in the state cookie, as shown in the following example:
quarkus.oidc.authentication.pkce-required=true
quarkus.oidc.authentication.state-secret=eUk1p7UB3nFiXZGUXi0uph1Y9p34YhBUIf you already have a 32-character client secret, you do not need to set the quarkus.oidc.authentication.pkce-secret property unless you prefer to use a different secret key.
This secret will be auto-generated if it is not configured and if the fallback to the client secret is not possible in cases where the client secret is less than 16 characters long.
The secret key is required to encrypt a randomly generated PKCE code_verifier while the user is redirected with the code_challenge query parameter to an OIDC provider to authenticate.
The code_verifier is decrypted when the user is redirected back to Quarkus and sent to the token endpoint alongside the code, client secret, and other parameters to complete the code exchange.
The provider will fail the code exchange if a SHA256 digest of the code_verifier does not match the code_challenge that was provided during the authentication request.
Handling and controlling the lifetime of authentication
Another important requirement for authentication is to ensure that the data the session is based on is up-to-date without requiring the user to authenticate for every single request. There are also situations where a logout event is explicitly requested. Use the following key points to find the right balance for securing your Quarkus applications:
Cookies
The OIDC adapter uses cookies to keep the session, code flow, and post-logout state. This state is a key element controlling the lifetime of authentication data.
Use the quarkus.oidc.authentication.cookie-path property to ensure that the same cookie is visible when you access protected resources with overlapping or different roots.
For example:
-
/index.htmland/web-app/service -
/web-app/service1and/web-app/service2 -
/web-app1/serviceand/web-app2/service
By default, quarkus.oidc.authentication.cookie-path is set to / but you can change this to a more specific path if required, for example, /web-app.
To set the cookie path dynamically, configure the quarkus.oidc.authentication.cookie-path-header property.
Set the quarkus.oidc.authentication.cookie-path-header property.
For example, to set the cookie path dynamically by using the value of the`X-Forwarded-Prefix` HTTP header, configure the property to quarkus.oidc.authentication.cookie-path-header=X-Forwarded-Prefix.
If quarkus.oidc.authentication.cookie-path-header is set but no configured HTTP header is available in the current request, then the quarkus.oidc.authentication.cookie-path will be checked.
If your application is deployed across multiple domains, set the quarkus.oidc.authentication.cookie-domain property so that the session cookie is visible to all protected Quarkus services.
For example, if you have Quarkus services deployed on the following two domains, then you must set the quarkus.oidc.authentication.cookie-domain property to company.net.
-
https://whatever.wherever.company.net/
-
https://another.address.company.net/
Session cookie and default TokenStateManager
OIDC CodeAuthenticationMechanism uses the default io.quarkus.oidc.TokenStateManager interface implementation to keep the ID, access, and refresh tokens returned in the authorization code or refresh grant responses in an encrypted session cookie.
It makes Quarkus OIDC endpoints completely stateless and it is recommended to follow this strategy to achieve the best scalability results.
See the Database TokenStateManager and Session cookie and custom TokenStateManager sections of this guide for alternative approaches to storing tokens. For example, storing tokens in the database or other server-side storage, if you prefer and have good reasons for storing the token state on the server.
You can configure the default TokenStateManager to avoid saving an access token in the session cookie and to only keep ID and refresh tokens or a single ID token only.
An access token is only required if the endpoint needs to do the following actions:
-
Retrieve
UserInfo -
Access the downstream service with this access token
-
Use the roles associated with the access token, which are checked by default
In such cases, use the quarkus.oidc.token-state-manager.strategy property to configure the token state strategy as follows:
| To… | Set the property to … |
|---|---|
Keep the ID and refresh tokens only |
|
Keep the ID token only |
|
If your chosen session cookie strategy combines tokens and generates a large session cookie value that is greater than 4KB, some browsers might not be able to handle such cookie sizes.
This can occur when the ID, access, and refresh tokens are JWT tokens and the selected strategy is keep-all-tokens or with ID and refresh tokens when the strategy is id-refresh-token.
To work around this issue, you can set quarkus.oidc.token-state-manager.split-tokens=true to create a unique session token for each token.
An alternative solution is to have the tokens saved in the database.
For more information, see Database TokenStateManager.
The default TokenStateManager encrypts the tokens before storing them in the session cookie.
The following example shows how you configure it to split the tokens and encrypt them:
quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus
quarkus.oidc.client-id=quarkus-app
quarkus.oidc.credentials.secret=secret
quarkus.oidc.application-type=web-app
quarkus.oidc.token-state-manager.split-tokens=true
quarkus.oidc.token-state-manager.encryption-secret=eUk1p7UB3nFiXZGUXi0uph1Y9p34YhBUThe token encryption secret must be at least 32 characters long.
If this key is not configured, then either quarkus.oidc.credentials.secret or quarkus.oidc.credentials.jwt.secret will be hashed to create an encryption key.
Configure the quarkus.oidc.token-state-manager.encryption-secret property if Quarkus authenticates to the OIDC provider by using one of the following authentication methods:
-
mTLS
-
private_key_jwt, where a private RSA or EC key is used to sign a JWT token
Otherwise, a random key is generated, which can be problematic if the Quarkus application is running in the cloud with multiple pods managing the requests.
You can disable token encryption in the session cookie by setting quarkus.oidc.token-state-manager.encryption-required=false.
Session cookie and custom TokenStateManager
If you want to customize the way the tokens are associated with the session cookie, register a custom io.quarkus.oidc.TokenStateManager' implementation as an `@ApplicationScoped CDI bean.
For example, you might want to keep the tokens in a cache cluster and have only a key stored in a session cookie. Note that this approach might introduce some challenges if you need to make the tokens available across multiple microservices nodes.
Here is a simple example:
package io.quarkus.oidc.test;

Database TokenStateManager
If you prefer to follow a stateful token storage strategy, you can use a custom TokenStateManager provided by Quarkus to have your application store tokens in a database, instead of storing them in an encrypted session cookie, which is done by default as described in the Session cookie and default TokenStateManager section.
To use this feature, add the following extension to your project:
quarkus extension add oidc-db-token-state-manager./mvnw quarkus:add-extension -Dextensions='oidc-db-token-state-manager'./gradlew addExtension --extensions='oidc-db-token-state-manager'This extension will replace the default `io.quarkus.oidc.TokenStateManager' with a database-based one.
OIDC Database Token State Manager uses a Reactive SQL client under the hood to avoid blocking because the authentication is likely to happen on an IO thread.
Depending on your database, include and configure exactly one Reactive SQL client. The following Reactive SQL clients are supported:
-
Reactive Microsoft SQL client
-
Reactive MySQL client
-
Reactive PostgreSQL client
-
Reactive Oracle client
-
Reactive DB2 client
| Your application is not required to switch to using the Reactive SQL client if it already uses Hibernate ORM with one of the JDBC driver extensions. |
For example, you already have an application that uses the Hibernate ORM extension together with a PostgreSQL JDBC Driver and your datasource is configured like this:
quarkus.datasource.db-kind=postgresql
quarkus.datasource.username=quarkus_test
quarkus.datasource.password=quarkus_test
quarkus.datasource.jdbc.url=jdbc:postgresql://localhost:5432/quarkus_testNow, if you decided to use OIDC Database Token State Manager, you must add the following dependencies and set a reactive driver URL:
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-oidc-db-token-state-manager</artifactId>
</dependency>
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-reactive-pg-client</artifactId>
</dependency>implementation("io.quarkus:quarkus-oidc-db-token-state-manager")
implementation("io.quarkus:quarkus-reactive-pg-client")quarkus.datasource.reactive.url=postgresql://localhost:5432/quarkus_testNow, the tokens are ready to be stored in the database.
By default, a database table used for storing tokens is created for you, however, you can disable this option with the quarkus.oidc.db-token-state-manager.create-database-table-if-not-exists configuration property.
Should you want the Hibernate ORM extension to create this table instead, you must just include an Entity, such as the following:
package org.acme.manager;
import jakarta.persistence.Column;
import jakarta.persistence.Entity;
import jakarta.persistence.Id;
import jakarta.persistence.Table;
@Table(name = "oidc_db_token_state_manager") (1)
@Entity
public class OidcDbTokenStateManagerEntity {
@Id
String id;
@Column(name = "id_token", length = 4000) (2)
String idToken;
@Column(name = "refresh_token", length = 4000)
String refreshToken;
@Column(name = "access_token", length = 4000)
String accessToken;
@Column(name = "expires_in")
Long expiresIn;
}| 1 | The Hibernate ORM extension will only create this table for you when the database schema is generated. For more information, refer to the Hibernate ORM guide. |
| 2 | You can choose a column length depending on the length of your tokens. |
Logout and expiration
There are two main ways for the authentication information to expire: the tokens expired and were not renewed or an explicit logout operation was triggered.
Let’s start with explicit logout operations.
User-initiated logout
Users can request a logout by sending a request to the Quarkus endpoint logout path set with a quarkus.oidc.logout.path property.
For example, if the endpoint address is https://application.com/webapp and the quarkus.oidc.logout.path is set to "/logout", then the logout request must be sent to https://application.com/webapp/logout.
This logout request starts an RP-initiated logout. The user will be redirected to the OIDC provider to log out, where they can be asked to confirm the logout is indeed intended.
The user will be returned to the endpoint post-logout page once the logout has been completed and if the quarkus.oidc.logout.post-logout-path property is set.
For example, if the endpoint address is https://application.com/webapp and the quarkus.oidc.logout.post-logout-path is set to "/signin", then the user will be returned to https://application.com/webapp/signin.
Note, this URI must be registered as a valid post_logout_redirect_uri in the OIDC provider.
If the quarkus.oidc.logout.post-logout-path is set, then a q_post_logout cookie will be created and a matching state query parameter will be added to the logout redirect URI and the OIDC provider will return this state once the logout has been completed.
It is recommended for the Quarkus web-app applications to check that a state query parameter matches the value of the q_post_logout cookie, which can be done, for example, in a Jakarta REST filter.
Note that a cookie name varies when using OpenID Connect Multi-Tenancy.
For example, it will be named q_post_logout_tenant_1 for a tenant with a tenant_1 ID, and so on.
Here is an example of how to configure a Quarkus application to initiate a logout flow:
quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus
quarkus.oidc.client-id=frontend
quarkus.oidc.credentials.secret=secret
quarkus.oidc.application-type=web-app
quarkus.oidc.logout.path=/logout
# Logged-out users should be returned to the /welcome.html site which will offer an option to re-login:
quarkus.oidc.logout.post-logout-path=/welcome.html
# Only the authenticated users can initiate a logout:
quarkus.http.auth.permission.authenticated.paths=/logout
quarkus.http.auth.permission.authenticated.policy=authenticated
# All users can see the Welcome page:
quarkus.http.auth.permission.public.paths=/welcome.html
quarkus.http.auth.permission.public.policy=permitYou might also want to set quarkus.oidc.authentication.cookie-path to a path value common to all the application resources, which is / in this example.
For more information, see the Cookies section.
|
Some OIDC providers do not support a RP-initiated logout specification and do not return an OpenID Connect well-known According to the RP-initiated logout specification, the You can use |
Back-channel logout
The OIDC provider can force the logout of all applications by using the authentication data. This is known as back-channel logout. In this case, the OIDC will call a specific URL from each application to trigger that logout.
OIDC providers use Back-channel logout to log out the current user from all the applications into which this user is currently logged in, bypassing the user agent.
You can configure Quarkus to support Back-channel logout as follows:
quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus
quarkus.oidc.client-id=frontend
quarkus.oidc.credentials.secret=secret
quarkus.oidc.application-type=web-app
quarkus.oidc.logout.backchannel.path=/back-channel-logoutThe absolute back-channel logout URL is calculated by adding quarkus.oidc.back-channel-logout.path to the current endpoint URL, for example, http://localhost:8080/back-channel-logout.
You will need to configure this URL in the admin console of your OIDC provider.
You will also need to configure a token age property for the logout token verification to succeed if your OIDC provider does not set an expiry claim in the current logout token.
For example, set quarkus.oidc.token.age=10S to ensure that no more than 10 seconds elapse since the logout token’s iat (issued at) time.
Front-channel logout
You can use Front-channel logout to log out the current user directly from the user agent, for example, its browser. It is similar to Back-channel logout but the logout steps are executed by the user agent, such as the browser, and not in the background by the OIDC provider. This option is rarely used.
You can configure Quarkus to support Front-channel logout as follows:
quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus
quarkus.oidc.client-id=frontend
quarkus.oidc.credentials.secret=secret
quarkus.oidc.application-type=web-app
quarkus.oidc.logout.frontchannel.path=/front-channel-logoutThis path will be compared to the current request’s path, and the user will be logged out if these paths match.
Local logout
User-initiated logout will log the user out of the OIDC provider. If it is used as single sign-on, it might not be what you require. If, for example, your OIDC provider is Google, you will be logged out from Google and its services. Instead, the user might just want to log out of that specific application. Another use case might be when the OIDC provider does not have a logout endpoint.
By using OidcSession, you can support a local logout, which means that only the local session cookie is cleared, as shown in the following example:
import jakarta.inject.Inject;
import jakarta.ws.rs.GET;
import jakarta.ws.rs.Path;
import io.quarkus.oidc.OidcSession;
@Path("/service")
public class ServiceResource {
@Inject
OidcSession oidcSession;
@GET
@Path("logout")
public String logout() {
oidcSession.logout().await().indefinitely();
return "You are logged out".
}Using OidcSession for local logout
io.quarkus.oidc.OidcSession is a wrapper around the current IdToken, which can help to perform a Local logout, retrieve the current session’s tenant identifier, and check when the session will expire.
More useful methods will be added to it over time.
Session management
By default, logout is based on the expiration time of the ID token issued by the OIDC provider. When the ID token expires, the current user session at the Quarkus endpoint is invalidated, and the user is redirected to the OIDC provider again to authenticate. If the session at the OIDC provider is still active, users are automatically re-authenticated without needing to provide their credentials again.
The current user session can be automatically extended by enabling the quarkus.oidc.token.refresh-expired property.
If set to true, when the current ID token expires, a refresh token grant will be used to refresh the ID token as well as access and refresh tokens.
|
If you have a single page application for service applications where your OIDC provider script such as |
If you work with a Quarkus OIDC web-app application, then the Quarkus OIDC code authentication mechanism manages the user session lifespan.
To use the refresh token, you should carefully configure the session cookie age. The session age should be longer than the ID token lifespan and close to or equal to the refresh token lifespan.
You calculate the session age by adding the lifespan value of the current ID token and the values of the quarkus.oidc.authentication.session-age-extension and quarkus.oidc.token.lifespan-grace properties.
|
You use only the |
When the current authenticated user returns to the protected Quarkus endpoint and the ID token associated with the session cookie has expired, then, by default, the user is automatically redirected to the OIDC Authorization endpoint to re-authenticate. The OIDC provider might challenge the user again if the session between the user and this OIDC provider is still active, which might happen if the session is configured to last longer than the ID token.
If the quarkus.oidc.token.refresh-expired is set to true, then the expired ID token (and the access token) is refreshed by using the refresh token returned with the initial authorization code grant response.
This refresh token might also be recycled (refreshed) itself as part of this process.
As a result, the new session cookie is created, and the session is extended.
|
In instances where the user is not very active, you can use the |
You can go one step further and proactively refresh ID tokens or access tokens that are about to expire.
Set quarkus.oidc.token.refresh-token-time-skew to the value you want to anticipate the refresh.
If, during the current user request, it is calculated that the current ID token will expire within this quarkus.oidc.token.refresh-token-time-skew, then it is refreshed, and the new session cookie is created.
This property should be set to a value that is less than the ID token lifespan; the closer it is to this lifespan value, the more often the ID token is refreshed.
You can further optimize this process by having a simple JavaScript function ping your Quarkus endpoint periodically to emulate the user activity, which minimizes the time frame during which the user might have to be re-authenticated.
|
You cannot extend the user session indefinitely. The returning user with the expired ID token will have to re-authenticate at the OIDC provider endpoint once the refresh token has expired. |
Integration with GitHub and non-OIDC OAuth2 providers
Some well-known providers such as GitHub or LinkedIn are not OpenID Connect providers, but OAuth2 providers that support the authorization code flow.
For example, GitHub OAuth2 and LinkedIn OAuth2.
Remember, OIDC is built on top of OAuth2.
The main difference between OIDC and OAuth2 providers is that OIDC providers return an ID Token that represents a user authentication, in addition to the standard authorization code flow access and refresh tokens returned by OAuth2 providers.
OAuth2 providers such as GitHub do not return IdToken, and the user authentication is implicit and indirectly represented by the access token.
This access token represents an authenticated user authorizing the current Quarkus web-app application to access some data on behalf of the authenticated user.
For OIDC, you validate the ID token as proof of authentication validity whereas in the case of OAuth2, you validate the access token.
This is done by subsequently calling an endpoint that requires the access token and that typically returns user information.
This approach is similar to the OIDC UserInfo approach, with UserInfo fetched by Quarkus OIDC on your behalf.
For example, when working with GitHub, the Quarkus endpoint can acquire an access token, which allows the Quarkus endpoint to request a GitHub profile for the current user.
To support the integration with such OAuth2 servers, quarkus-oidc needs to be configured a bit differently to allow the authorization code flow responses without IdToken: quarkus.oidc.authentication.id-token-required=false.
|
Even though you configure the extension to support the authorization code flows without This simplifies how you handle an application that supports multiple OIDC providers. |
The next step is to ensure that the returned access token can be useful and is valid to the current Quarkus endpoint.
The first way is to call the OAuth2 provider introspection endpoint by configuring quarkus.oidc.introspection-path, if the provider offers such an endpoint.
In this case, you can use the access token as a source of roles using quarkus.oidc.roles.source=accesstoken.
If no introspection endpoint is present, you can attempt instead to request UserInfo from the provider as it will at least validate the access token.
To do so, specify quarkus.oidc.token.verify-access-token-with-user-info=true.
You also need to set the quarkus.oidc.user-info-path property to a URL endpoint that fetches the user info (or to an endpoint protected by the access token).
For GitHub, since it does not have an introspection endpoint, requesting the UserInfo is required.
|
Requiring UserInfo involves making a remote call on every request.
Therefore, you might want to consider caching Alternatively, you might want to request that |
OAuth2 servers might not support a well-known configuration endpoint.
In this case, you must disable the discovery and configure the authorization, token, and introspection and UserInfo endpoint paths manually.
For well-known OIDC or OAuth2 providers, such as Apple, Facebook, GitHub, Google, Microsoft, Spotify, and Twitter, Quarkus can help significantly simplify your application’s configuration with the quarkus.oidc.provider property.
Here is how you can integrate quarkus-oidc with GitHub after you have created a GitHub OAuth application.
Configure your Quarkus endpoint like this:
quarkus.oidc.provider=github
quarkus.oidc.client-id=github_app_clientid
quarkus.oidc.credentials.secret=github_app_clientsecret
# user:email scope is requested by default, use 'quarkus.oidc.authentication.scopes' to request different scopes such as `read:user`.
# See https://docs.github.com/en/developers/apps/building-oauth-apps/scopes-for-oauth-apps for more information.
# Consider enabling UserInfo Cache
# quarkus.oidc.token-cache.max-size=1000
# quarkus.oidc.token-cache.time-to-live=5M
#
# Or having UserInfo cached inside IdToken itself
# quarkus.oidc.cache-user-info-in-idtoken=trueFor more information about configuring other well-known providers, see OpenID Connect providers.
This is all that is needed for an endpoint like this one to return the currently-authenticated user’s profile with GET http://localhost:8080/github/userinfo and access it as the individual UserInfo properties:
import jakarta.inject.Inject;
import jakarta.ws.rs.GET;
import jakarta.ws.rs.Path;
import jakarta.ws.rs.Produces;
import io.quarkus.oidc.UserInfo;
import io.quarkus.security.Authenticated;
@Path("/github")
@Authenticated
public class TokenResource {
@Inject
UserInfo userInfo;
@GET
@Path("/userinfo")
@Produces("application/json")
public String getUserInfo() {
return userInfo.getUserInfoString();
}
}If you support more than one social provider with the help of OpenID Connect Multi-Tenancy, for example, Google, which is an OIDC provider that returns IdToken, and GitHub, which is an OAuth2 provider that does not return IdToken and only allows access to UserInfo, then you can have your endpoint working with only the injected SecurityIdentity for both Google and GitHub flows.
A simple augmentation of SecurityIdentity will be required where a principal created with the internally-generated IdToken will be replaced with the UserInfo-based principal when the GitHub flow is active:
package io.quarkus.it.keycloak;
import java.security.Principal;
import jakarta.enterprise.context.ApplicationScoped;
import io.quarkus.oidc.UserInfo;
import io.quarkus.security.identity.AuthenticationRequestContext;
import io.quarkus.security.identity.SecurityIdentity;
import io.quarkus.security.identity.SecurityIdentityAugmentor;
import io.quarkus.security.runtime.QuarkusSecurityIdentity;
import io.smallrye.mutiny.Uni;
import io.vertx.ext.web.RoutingContext;
@ApplicationScoped
public class CustomSecurityIdentityAugmentor implements SecurityIdentityAugmentor {
@Override
public Uni<SecurityIdentity> augment(SecurityIdentity identity, AuthenticationRequestContext context) {
RoutingContext routingContext = identity.getAttribute(RoutingContext.class.getName());
if (routingContext != null && routingContext.normalizedPath().endsWith("/github")) {
QuarkusSecurityIdentity.Builder builder = QuarkusSecurityIdentity.builder(identity);
UserInfo userInfo = identity.getAttribute("userinfo");
builder.setPrincipal(new Principal() {
@Override
public String getName() {
return userInfo.getString("preferred_username");
}
});
identity = builder.build();
}
return Uni.createFrom().item(identity);
}
}Now, the following code will work when the user signs into your application by using Google or GitHub:
import jakarta.inject.Inject;
import jakarta.ws.rs.GET;
import jakarta.ws.rs.Path;
import jakarta.ws.rs.Produces;
import io.quarkus.security.Authenticated;
import io.quarkus.security.identity.SecurityIdentity;
@Path("/service")
@Authenticated
public class TokenResource {
@Inject
SecurityIdentity identity;
@GET
@Path("/google")
@Produces("application/json")
public String getUserName() {
return identity.getPrincipal().getName();
}
@GET
@Path("/github")
@Produces("application/json")
public String getUserName() {
return identity.getPrincipal().getUserName();
}
}Possibly a simpler alternative is to inject both @IdToken JsonWebToken and UserInfo and use JsonWebToken when handling the providers that return IdToken and use UserInfo with the providers that do not return IdToken.
You must ensure that the callback path you enter in the GitHub OAuth application configuration matches the endpoint path where you want the user to be redirected after a successful GitHub authentication and application authorization.
In this case, it has to be set to http:localhost:8080/github/userinfo.
Listening to important authentication events
You can register the @ApplicationScoped bean which will observe important OIDC authentication events.
When a user logs in for the first time, re-authenticates, or refreshes the session, the listener is updated.
In the future, more events might be reported.
For example:
import jakarta.enterprise.context.ApplicationScoped;
import jakarta.enterprise.event.Observes;
import io.quarkus.oidc.IdTokenCredential;
import io.quarkus.oidc.SecurityEvent;
import io.quarkus.security.identity.AuthenticationRequestContext;
import io.vertx.ext.web.RoutingContext;
@ApplicationScoped
public class SecurityEventListener {
public void event(@Observes SecurityEvent event) {
String tenantId = event.getSecurityIdentity().getAttribute("tenant-id");
RoutingContext vertxContext = event.getSecurityIdentity().getAttribute(RoutingContext.class.getName());
vertxContext.put("listener-message", String.format("event:%s,tenantId:%s", event.getEventType().name(), tenantId));
}
}| You can listen to other security events as described in the Observe security events section of the Security Tips and Tricks guide. |
Propagating tokens to downstream services
For information about Authorization Code Flow access token propagation to downstream services, see the Token Propagation section.
Integration considerations
Your application secured by OIDC integrates in an environment where it can be called from single-page applications. It must work with well-known OIDC providers, run behind HTTP Reverse Proxy, require external and internal access, and so on.
This section discusses these considerations.
Single-page applications
You can check if implementing single-page applications (SPAs) the way it is suggested in the Single-page applications section of the "OpenID Connect (OIDC) Bearer token authentication" guide meets your requirements.
If you prefer to use SPAs and JavaScript APIs such as Fetch or XMLHttpRequest(XHR) with Quarkus web applications, be aware that OIDC providers might not support cross-origin resource sharing (CORS) for authorization endpoints where the users are authenticated after a redirect from Quarkus.
This will lead to authentication failures if the Quarkus application and the OIDC provider are hosted on different HTTP domains, ports, or both.
In such cases, set the quarkus.oidc.authentication.java-script-auto-redirect property to false, which will instruct Quarkus to return a 499 status code and a WWW-Authenticate header with the OIDC value.
The browser script must set a header to identify the current request as a JavaScript request for a 499 status code to be returned when the quarkus.oidc.authentication.java-script-auto-redirect property is set to false.
If the script engine sets an engine-specific request header itself, then you can register a custom quarkus.oidc.JavaScriptRequestChecker bean, which will inform Quarkus if the current request is a JavaScript request. For example, if the JavaScript engine sets a header such as HX-Request: true, then you can have it checked like this:
import jakarta.enterprise.context.ApplicationScoped;
import io.quarkus.oidc.JavaScriptRequestChecker;
import io.vertx.ext.web.RoutingContext;
@ApplicationScoped
public class CustomJavaScriptRequestChecker implements JavaScriptRequestChecker {
@Override
public boolean isJavaScriptRequest(RoutingContext context) {
return "true".equals(context.request().getHeader("HX-Request"));
}
}and reload the last requested page in case of a 499 status code.
Otherwise, you must also update the browser script to set the X-Requested-With header with the JavaScript value and reload the last requested page in case of a 499 status code.
例如：
Future<void> callQuarkusService() async {
Map<String, String> headers = Map.fromEntries([MapEntry("X-Requested-With", "JavaScript")]);
await http
.get("https://localhost:443/serviceCall")
.then((response) {
if (response.statusCode == 499) {
window.location.assign("https://localhost.com:443/serviceCall");
}
});
}Cross-Origin 资源共享
If you plan to consume this application from a single-page application running on a different domain, you need to configure cross-origin resource sharing (CORS). For more information, see the CORS filter section of the "Cross-origin resource sharing" guide.
Calling Cloud provider services
Google Cloud
You can have Quarkus OIDC web-app applications access Google Cloud services such as BigQuery on behalf of the currently authenticated users who have enabled OIDC authorization code flow permissions to such services in their Google developer consoles.
You can do so by using Quarkiverse Google Cloud Services. You need only to add the latest tag service dependency as shown in the following example:
<dependency>
<groupId>io.quarkiverse.googlecloudservices</groupId>
<artifactId>quarkus-google-cloud-bigquery</artifactId>
<version>${quarkiverse.googlecloudservices.version}</version>
</dependency>implementation("io.quarkiverse.googlecloudservices:quarkus-google-cloud-bigquery:${quarkiverse.googlecloudservices.version}")Then, configure Google OIDC properties:
quarkus.oidc.provider=google
quarkus.oidc.client-id={GOOGLE_CLIENT_ID}
quarkus.oidc.credentials.secret={GOOGLE_CLIENT_SECRET}
quarkus.oidc.token.issuer=https://accounts.google.comRunning Quarkus application behind a reverse proxy
The OIDC authentication mechanism can be affected if your Quarkus application is running behind a reverse proxy, gateway, or firewall when HTTP Host header might be reset to the internal IP address and HTTPS connection might be terminated, and so on.
For example, an authorization code flow redirect_uri parameter might be set to the internal host instead of the expected external one.
In such cases, configuring Quarkus to recognize the original headers forwarded by the proxy will be required. For more information, see the Running behind a reverse proxy Vert.x documentation section.
For example, if your Quarkus endpoint runs in a cluster behind Kubernetes Ingress, then a redirect from the OIDC provider back to this endpoint might not work because the calculated redirect_uri parameter might point to the internal endpoint address.
You can resolve this problem by using the following configuration, where X-ORIGINAL-HOST is set by Kubernetes Ingress to represent the external endpoint address.:
quarkus.http.proxy.proxy-address-forwarding=true
quarkus.http.proxy.allow-forwarded=false
quarkus.http.proxy.enable-forwarded-host=true
quarkus.http.proxy.forwarded-host-header=X-ORIGINAL-HOSTquarkus.oidc.authentication.force-redirect-https-scheme property can also be used when the Quarkus application is running behind an SSL terminating reverse proxy.
External and internal access to the OIDC provider
The OIDC provider externally-accessible authorization, logout, and other endpoints can have different HTTP(S) URLs compared to the URLs auto-discovered or configured relative to the quarkus.oidc.auth-server-url internal URL.
In such cases, the endpoint might report an issuer verification failure and redirects to the externally-accessible OIDC provider endpoints might fail.
If you work with Keycloak, then start it with a KEYCLOAK_FRONTEND_URL system property set to the externally-accessible base URL.
If you work with other OIDC providers, check the documentation of your provider.
OIDC SAML identity broker
If your identity provider does not implement OpenID Connect but only the legacy XML-based SAML2.0 SSO protocol, then Quarkus cannot be used as a SAML 2.0 adapter, similarly to how quarkus-oidc is used as an OIDC adapter.
However, many OIDC providers such as Keycloak, Okta, Auth0, and Microsoft ADFS offer OIDC to SAML 2.0 bridges.
You can create an identity broker connection to a SAML 2.0 provider in your OIDC provider and use quarkus-oidc to authenticate your users to this SAML 2.0 provider, with the OIDC provider coordinating OIDC and SAML 2.0 communications.
As far as Quarkus endpoints are concerned, they can continue using the same Quarkus Security, OIDC API, annotations such as @Authenticated, SecurityIdentity, and so on.
For example, assume Okta is your SAML 2.0 provider and Keycloak is your OIDC provider.
Here is a typical sequence explaining how to configure Keycloak to broker with the Okta SAML 2.0 provider.
First, create a new SAML2 integration in your Okta Dashboard/Applications:
For example, name it as OktaSaml:
Next, configure it to point to a Keycloak SAML broker endpoint.
At this point, you need to know the name of the Keycloak realm, for example, quarkus, and, assuming that the Keycloak SAML broker alias is saml, enter the endpoint address as http:localhost:8081/realms/quarkus/broker/saml/endpoint.
Enter the service provider (SP) entity ID as http:localhost:8081/realms/quarkus, where http://localhost:8081 is a Keycloak base address and saml is a broker alias:
Next, save this SAML integration and note its Metadata URL:
Next, add a SAML provider to Keycloak:
First, as usual, create a new realm or import the existing realm to Keycloak.
In this case, the realm name has to be quarkus.
Now, in the quarkus realm properties, navigate to Identity Providers and add a new SAML provider:
Note the alias is set to saml, Redirect URI is http:localhost:8081/realms/quarkus/broker/saml/endpoint and Service provider entity ID is http:localhost:8081/realms/quarkus - these are the same values you entered when creating the Okta SAML integration in the previous step.
Finally, set Service entity descriptor to point to the Okta SAML Integration Metadata URL you noted at the end of the previous step.
Next, if you want, you can register this Keycloak SAML provider as a default provider by navigating to Authentication/browser/Identity Provider Redirector config and setting both the Alias and Default Identity Provider properties to saml.
If you do not configure it as a default provider then, at authentication time, Keycloak offers 2 options:
-
Authenticate with the SAML provider
-
Authenticate directly to Keycloak with the name and password
Now, configure the Quarkus OIDC web-app application to point to the Keycloak quarkus realm, quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus.
Then, you are ready to start authenticating your Quarkus users to the Okta SAML 2.0 provider by using an OIDC to SAML bridge that is provided by Keycloak OIDC and Okta SAML 2.0 providers.
You can configure other OIDC providers to provide a SAML bridge similarly to how it can be done for Keycloak.
测试
Testing is often tricky when it comes to authentication to a separate OIDC-like server. Quarkus offers several options from mocking to a local run of an OIDC provider.
首先在你的测试项目中添加以下依赖项：
<dependency>
<groupId>net.sourceforge.htmlunit</groupId>
<artifactId>htmlunit</artifactId>
<exclusions>
<exclusion>
<groupId>org.eclipse.jetty</groupId>
<artifactId>*</artifactId>
</exclusion>
</exclusions>
<scope>test</scope>
</dependency>
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-junit5</artifactId>
<scope>test</scope>
</dependency>testImplementation("net.sourceforge.htmlunit:htmlunit")
testImplementation("io.quarkus:quarkus-junit5")Wiremock
添加以下依赖关系：
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-test-oidc-server</artifactId>
<scope>test</scope>
</dependency>testImplementation("io.quarkus:quarkus-test-oidc-server")Prepare the REST test endpoints and set application.properties.
For example:
# keycloak.url is set by OidcWiremockTestResource
quarkus.oidc.auth-server-url=${keycloak.url}/realms/quarkus/
quarkus.oidc.client-id=quarkus-web-app
quarkus.oidc.credentials.secret=secret
quarkus.oidc.application-type=web-appFinally, write the test code, for example:
import static org.junit.jupiter.api.Assertions.assertEquals;
import org.junit.jupiter.api.Test;
import com.gargoylesoftware.htmlunit.SilentCssErrorHandler;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlForm;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
import io.quarkus.test.common.QuarkusTestResource;
import io.quarkus.test.junit.QuarkusTest;
import io.quarkus.test.oidc.server.OidcWiremockTestResource;
@QuarkusTest
@QuarkusTestResource(OidcWiremockTestResource.class)
public class CodeFlowAuthorizationTest {
@Test
public void testCodeFlow() throws Exception {
try (final WebClient webClient = createWebClient()) {
// the test REST endpoint listens on '/code-flow'
HtmlPage page = webClient.getPage("http://localhost:8081/code-flow");
HtmlForm form = page.getFormByName("form");
// user 'alice' has the 'user' role
form.getInputByName("username").type("alice");
form.getInputByName("password").type("alice");
page = form.getInputByValue("login").click();
assertEquals("alice", page.getBody().asText());
}
}
private WebClient createWebClient() {
WebClient webClient = new WebClient();
webClient.setCssErrorHandler(new SilentCssErrorHandler());
return webClient;
}
}OidcWiremockTestResource recognizes alice and admin users.
The user alice has the user role only by default - it can be customized with a quarkus.test.oidc.token.user-roles system property.
The user admin has the user and admin roles by default - it can be customized with a quarkus.test.oidc.token.admin-roles system property.
Additionally, OidcWiremockTestResource sets the token issuer and audience to https://service.example.com, which can be customized with quarkus.test.oidc.token.issuer and quarkus.test.oidc.token.audience system properties.
OidcWiremockTestResource can be used to emulate all OIDC providers.
为Keycloak提供的开发服务
Using Dev Services for Keycloak is recommended for integration testing against Keycloak.
Dev Services for Keycloak will start and initialize a test container: it will create a quarkus realm, a quarkus-app client (secret secret), and add alice (admin and user roles) and bob (user role) users, where all of these properties can be customized.
First, prepare application.properties.
You can start with a completely empty application.properties file as Dev Services for Keycloak will register quarkus.oidc.auth-server-url pointing to the running test container as well as quarkus.oidc.client-id=quarkus-app and quarkus.oidc.credentials.secret=secret.
However, if you already have all the required quarkus-oidc properties configured, then you only need to associate quarkus.oidc.auth-server-url with the prod profile for Dev Services for Keycloak to start a container.
For example:
%prod.quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkusIf a custom realm file has to be imported into Keycloak before running the tests, then you can configure Dev Services for Keycloak as follows:
%prod.quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus
quarkus.keycloak.devservices.realm-path=quarkus-realm.jsonFinally, write a test code the same way as it is described in the Wiremock section.
The only difference is that @QuarkusTestResource is no longer needed:
@QuarkusTest
public class CodeFlowAuthorizationTest {
}Using KeycloakTestResourceLifecycleManager
Use KeycloakTestResourceLifecycleManager for your tests only if there is a good reason not to use Dev Services for Keycloak.
If you need to do the integration testing against Keycloak then you are encouraged to do it with Dev Services for Keycloak.
First, add the following dependency:
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-test-keycloak-server</artifactId>
<scope>test</scope>
</dependency>testImplementation("io.quarkus:quarkus-test-keycloak-server")This provides io.quarkus.test.keycloak.server.KeycloakTestResourceLifecycleManager - an implementation of io.quarkus.test.common.QuarkusTestResourceLifecycleManager which starts a Keycloak container.
Then, configure the Maven Surefire plugin as follows (and similarly the Maven Failsafe plugin when testing in native image):
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<systemPropertyVariables>
<!-- or, alternatively, configure 'keycloak.version' -->
<keycloak.docker.image>${keycloak.docker.image}</keycloak.docker.image>
<!--
Disable HTTPS if required:
<keycloak.use.https>false</keycloak.use.https>
-->
</systemPropertyVariables>
</configuration>
</plugin>Now, set the configuration and write the test code the same way as it is described in the Wiremock section.
The only difference is the name of QuarkusTestResource:
import io.quarkus.test.keycloak.server.KeycloakTestResourceLifecycleManager;
@QuarkusTest
@QuarkusTestResource(KeycloakTestResourceLifecycleManager.class)
public class CodeFlowAuthorizationTest {
}KeycloakTestResourceLifecycleManager 注册 alice 和 admin 用户。默认情况下，用户 alice 仅具有 user 角色 - 可以使用 keycloak.token.user-roles 系统属性对其进行自定义。默认情况下，用户 admin 具有 用户 和 admin 角色 - 可以使用 keycloak.token.admin-roles 系统属性对其进行自定义。
By default, KeycloakTestResourceLifecycleManager uses HTTPS to initialize a Keycloak instance that can be disabled by specifying keycloak.use.https=false.
The default realm name is quarkus and client id is quarkus-web-app - set keycloak.realm and keycloak.web-app.client system properties to customize the values if needed.
TestSecurity注解
You can use @TestSecurity and @OidcSecurity annotations to test the web-app application endpoint code, which depends on either one of the following injections, or all four:
-
ID
JsonWebToken -
Access
JsonWebToken -
UserInfo -
OidcConfigurationMetadata
For more information, see Use TestingSecurity with injected JsonWebToken.
Checking errors in the logs
To see details about the token verification errors, you must enable io.quarkus.oidc.runtime.OidcProvider TRACE level logging:
quarkus.log.category."io.quarkus.oidc.runtime.OidcProvider".level=TRACE
quarkus.log.category."io.quarkus.oidc.runtime.OidcProvider".min-level=TRACETo see details about the OidcProvider client initialization errors, enable io.quarkus.oidc.runtime.OidcRecorder TRACE level logging:
quarkus.log.category."io.quarkus.oidc.runtime.OidcRecorder".level=TRACE
quarkus.log.category."io.quarkus.oidc.runtime.OidcRecorder".min-level=TRACEFrom the quarkus dev console, type j to change the application global log level.
