Spring boot keycloak 身份验证失败

Question

我正在使用 keycloak 来验证我的 Spring Boot API 应用程序。

keycloak配置如下：

 keycloak:
   realm: totallr
   resource: totall_api
   ssl-required: external
   bearer-only: true
   auth-server-url: <my-server-with-port-commented-out>/auth

这样可以正常工作。但是当我通过 JVM args 更改一些配置时，它会失败并显示以下堆栈跟踪。我更改的配置是从本地主机到原始域和服务器端口号的 CORS 来源。

我遇到这个问题是因为我的 keycloak 服务器和我的资源服务器在一个带有 docker 的虚拟网络中一起运行，所以我的设置 auth-server-url: localhost/auth 不允许资源服务器访问 keycloak 以检查不记名令牌。

对此的解决方法似乎是使用localhost 以外的地址，并根据此响应为您的本地浏览器和资源服务器伪造 DNS 解析：Keycloak and Spring Boot web app in dockerized environment
