如何从keycloak中的自定义客户端获取角色？

为了获得自定义客户端中的角色，我知道我需要执行两个 API。一种是获取访问令牌，一种是获取角色。我的疑问是，我应该通过在标头中发送 admin-CLI 详细信息来获取 accessToken 还是因为我想要我创建的自定义客户端的角色？因为，我在尝试获取角色时收到unknown_error。

获取accessToken：

curl -X POST \
  http://localhost:8080/auth/realms/test-keycloak-example/protocol/openid-connect/token \
  -H 'cache-control: no-cache' \
  -H 'content-type: application/x-www-form-urlencoded' \
  -d 'grant_type=client_credentials&client_id=test-keycloak-example&client_secret=shhh'

获取角色：

curl -X GET \
  http://localhost:8080/auth/admin/realms/test-keycloak-example/clients/cb11fd17-46df-419a-9c67-4a69d1be66ae/roles \
  -H 'authorization: Bearer <token received from previous call> \
  -H 'cache-control: no-cache' \
  -H 'postman-token: 248fef6b-9c24-3aa3-91ae-a6f11e01e55c'

响应是：

{
   "error": "unknown_error"
}

Using Postman and three conditions should support it. #1 "test-user" needs a "view-clients" role. It comes from "realm-management" client.

#2 Using "admin-cli" client and Change Access Type with "confidential" and turn on "Authorization Enabled" is "ON"

#3 using "admin-cli"'s secret for Postman token call.

#4 使用 #3 的秘密和 #1 用户的凭据（用户名和密码）获取令牌

• the token "expires_in" is very short, you need to makes a longer by UI. it is admin-cli's advanced settings(for just testing purpose)

#5 你需要保存一个用于调用客户端/角色API的令牌

• it is same #4's API on Tests Tab of Postman.

#6 Call list client/role API with #5's token.

#7 find "custom-client" id from #6

#8 call custom role API using #7 id. it should be match with UI's roles.

祝你好运！
