Question

我们间歇性地（并且非常难以复制它，除了一个用户）在使用Keycloak 3.3.0 Final时收到此错误消息。这是在尝试使用Google进行身份验证时。

堆栈跟踪在这里：

我们复制这种方式的方法是用户退出应用程序，重新登录（此时他们注意到需要很长时间才能进行身份验证），点击刷新并将它们带到（keycloak）提示询问他们的用户凭据。当他们提供这些凭据时，它会给他们错误，＆＃34;我们很抱歉...使用身份提供商进行身份验证时出现意外错误＆＃34;

这是后端的错误。它似乎与Oauth2身份验证有关。

我猜测用户正在尝试刷新过程中的某些内容会导致访问令牌出现问题？也许初始登录生成一个但是刷新了？

很难很好地调试此错误，因为我无法在我的任何设备上重现它，即使遵循相同的工作流程，并且要求用户的手机是..是不可行的。

有没有人知道这里会发生什么？

Answer 1

我对OpenIdConnect和Google如何实现它有很多了解。我不知道Keycloak。我认为可能发生的事情是，在Keycloak方面，为Google服务器的OpenId身份验证请求设置了加密随机数，这是大多数OIDC集成所做的事情。然后刷新可能使nonce无效，因此当从Google到Keycloak的回调发生时，Keycloak决定回调不包含正确的nonce，因此抛出错误。有些实现可以在刷新后继续存在，但是其他实现 - 比如这个？ - 可能不会。

是否可以调试org.keycloak.broker.oidc.OIDCIdentityProvider.verifyAccessToken方法？我认为这是确定问题确切原因的最佳方法。

如果无法做到这一点，那么查看调用您自己服务器的回调的参数会很有趣。你能在你的访问日志中找到它吗？

Answer 2

请检查您的client_secret。更改client_secret后，我的Azure AD作为身份提供者也遇到了类似的问题，一切正常。

无法进行身份提供者oauth回调：org.keycloak.broker.provider.IdentityBrokerException：服务器
