pac4j raises "State cannot be determined" when trying to get keycloakOidcProfile after OIDC callback and Keycloak provider

问题

I am trying to implement pac4j openid with keycloak in Spring WebFlux project with JAVA 19 and Spring Boot 3.0.3.
I am also facing the same issue while fetching KeycloakOidcProfile after authentication is done in Keycloak.

I notice that when it redirects to the Keycloak login page, it sets a SESSION cookie, and at the end when the callback URL comes, it gets that SESSION cookie. The cookie is not getting changed, but I'm still getting this same error.

I am getting "Referrer-policy" variable as "no-referrer" in the header from Keycloak. Is this causing the problem? Could you please guide me on how to resolve this?

public Mono<keycloakOidcProfile> getUserProfile(ServerRequest serverRequest) {
        return Mono.just(serverRequest)
                .flatMap(serverRequest1 -> {
                    if (ObjectUtils.isNotEmpty(serverRequest1.queryParams().get("code"))) {
                        //getting code from url
                        System.out.println(serverRequest1.queryParam("code").get());
                    }
                    final WebContext context = new SpringWebfluxWebContext(serverRequest1.exchange());
                    final SessionStore sessionStore = new SpringWebfluxSessionStore(serverRequest1.exchange());
                    final ProfileManager profileManager = new ProfileManager(context,sessionStore);
                    
                    Optional<Credentials> credentials = config.getClients().findClient("KeycloakOidcClient").get().getCredentials(context,sessionStore);
                    Optional<UserProfile> userProfile = config.getClients().findClient("KeycloakOidcClient").get().getUserProfile(credentials.get(),context,sessionStore);
                    KeycloakOidcProfile keycloakOidcProfile = (KeycloakOidcProfile) userProfile.get();

                    System.out.println(keycloakOidcProfile.getAccessToken());

                    return keycloakOidcProfile;
                });
}

I am getting "Referrer-policy" variable as "no-referrer" in header from keycloak. Is this cause the problem?

如果您在成功登录Keycloak之前和之后具有相同的SESSION cookie,则应该可以正常工作。通常,这种问题是由于不希望的会话续订/丢失引起的。

您能否在org.pac4j.springframework.context.SpringWebfluxSessionStore类(会话存储)上启用DEBUG日志,以查看发生了什么情况?谢谢。

英文:

If you have the same SESSION cookie before and after the successful login at Keycloak, it should work. Generally, this kind of problem comes from an unwanted renewed/lost session.

Can you turn on DEBUG logs on the org.pac4j.springframework.context.SpringWebfluxSessionStore class (the session store) to see what's going on? Thx
