我应该显式验证 Keycloak 令牌还是由 Keycloak 适配器完成?

gai*_*jin 2 spring-security oauth-2.0 spring-boot bearer-token keycloak

有一个 Spring-boot REST API,需要由 Keycloak 保护,该应用程序使用 Keycloak-Spring-Security 适配器(6.0.1)。

对 API 端点的调用会携带从 Keycloak(当前通过邮递员)获取的不记名令牌。

我能够成功执行 REST 端点调用,但其他事情困扰着我 - 我是否应该根据公钥显式验证令牌?

1 - 适配器是否根据公钥执行令牌验证,还是我应该实施它?

2 - 如果适配器正在执行此操作 - 您能否指出这是在哪些类中完成的?

3 - 如果 - 不 - 应如何实施此验证?是否有任何 Keycloak 库可用于验证令牌?

好吧,经过几天的网络搜索答案——我明白了。我查看了Keycloak-spring-security-adapter的代码并找到了它。

首先,我得到了用于调试 keycloak 的日志记录杆:

logging.level.org.keycloak=DEBUG

然后我尝试使用错误的令牌访问我的端点(我预计这会产生异常,即更明显的跟踪;而且确实如此):

从那时起,很明显令牌正在被验证,如果您查看参与的类,您会发现在某些情况下它正在根据公钥进行验证。

在我的例子中,参与此身份验证和验证的类是 ( bearer-only):

org.keycloak.adapters.springsecurity.filter.KeycloakAuthenticationProcessingFilter
org.keycloak.adapters.BearerTokenRequestAuthenticator

希望这可以帮助像我一样的其他人在 Keycloak 中找到自己的路。
