php - 带有 Keycloak 的 Symfony OAuth2 返回 invalid_token : Token verification failed

Question

目标

我正在尝试使用 Keycloak 和库在 Symfony 6 中设置 OAuth2 knpuniversity/oauth2-client-bundle和 stevenmaguire/oauth2-keycloak .一切都使用 docker compose (v2.2) 进行设置，我正在使用 Traefik (v2.5) 作为代理。

问题

当尝试验证用户时，转到 /connect/keycloak 后，成功重定向到 https://keycloak.example.local/auth/realms/.../protocol/openid-connect/auth，登录成功并重定向回/connect/keycloak/check，我一直收到 token 验证失败的错误。

IdentityProviderException
HTTP 500 Internal Server Error
invalid_token: Token verification failed

对底层 guzzle 响应的进一步检查显示 401 statusCode 以及显示错误的 WWW-Authenticate header :

"Bearer realm="redacted", error="invalid_token", error_description="Token verification failed"

申请

我在我的 Symfony 6 (PHP 8.1) 应用程序中设置了以下内容:

config\packages\framework.yaml

    cookie_samesite: lax

将代理设置为外部网络。

key 斗篷

我已经按如下方式设置了客户端，并使用基本的Client Id 和 Secret(没有签名的 JWT)配置了 Credentials。

检查事件时，唯一不同的是第一个使用的 IP 地址。 LOGIN 操作使用客户端 IP，而 CODE_TO_TOKEN 操作使用 docker 容器的 IP。

不知道这是否与 token 验证失败有关。

此外， session 似乎已使用用户 ip 正确设置。

调试

尝试调试身份验证进度后，我注意到登录后返回的 access_token 与用于获取用户信息的相同。所以它没有改变或任何东西(我可以想象导致错误)。

已经(尝试)调试了 3 天，但我一无所获。似乎实际上没有找到可以帮助我进一步调试的类似案例。我不知道我是否遗漏了一些明显的东西，但我现在没主意了。感谢您提供任何帮助。

这对我有用。也许这对您也有帮助:https://github.com/stevenmaguire/oauth2-keycloak/issues/43#issuecomment-1066598308

好像是token里面的“issuer”有问题。
