Question

我试图在docker容器前面将keycloak-gatekeeper设置为反向代理，以便针对该容器提供身份验证和授权。我使用FusionAuth作为OIDC兼容的身份提供者，并已通过授权流程设法使keycloak-getekeeper可以使用它。当我尝试根据角色或组成员身份限制哪些用户可以访问资源时，就会出现问题。

当前，所有请求均被拒绝。当我查看服务器上的日志时，可以看到以下消息：

据我所知，我拒绝的原因是因为没有填充角色。我还运行了一个客户端来为用户获取JWT（通过隐式流），该客户端看起来像这样：

{
  "aud": "************************",
  "exp": 1554822076,
  "iat": 1554818476,
  "iss": "https://identity.*******.io",
  "sub": "****************",
  "authenticationType": "PASSWORD",
  "email": "someuser@domain.com",
  "email_verified": true,
  "applicationId": "*****************",
  "roles": [
    "role-1",
    "role-3"
  ]
}

由此，我可以看到用户处于正确的角色。

此刻，我对问题所在或如何更详细地调试keycloak-gatekeeper实例不知所措

keycloak-gatekeeper似乎只能处理keycloak（https://github.com/keycloak/keycloak-gatekeeper/blob/master/user_context.go）提供的令牌中的领域和客户端角色

以下是有问题的代码，可从令牌中提取角色：

// @step: extract the realm roles
    var roleList []string
    if realmRoles, found := claims[claimRealmAccess].(map[string]interface{}); found {
        if roles, found := realmRoles[claimResourceRoles]; found {
            for _, r := range roles.([]interface{}) {
                roleList = append(roleList, fmt.Sprintf("%s", r))
            }
        }
    }

    // @step: extract the client roles from the access token
    if accesses, found := claims[claimResourceAccess].(map[string]interface{}); found {
        for name, list := range accesses {
            scopes := list.(map[string]interface{})
            if roles, found := scopes[claimResourceRoles]; found {
                for _, r := range roles.([]interface{}) {
                    roleList = append(roleList, fmt.Sprintf("%s:%s", name, r))
                }
            }
        }
    }

这将解释为什么我的令牌中的要求没有出现

针对外部OIDC提供程序进行身份验证时，Keycloak-Gatekeeper不填充角色或组
