Spring Boot OAuth2授权代码流中出现InsufficientAuthenticationException

我创造了 Authorization Server Resource Server 它可以很好地与 password

我想测试来自邮递员的授权代码流。我发送这样一个请求以获取访问代码:

http://localhost:1111/oauth/authorize?response_type=code&client_id=test_client&redirect_uri=www.test_something.com

{
    "timestamp": "2018-09-27T21:02:14Z",
    "status": 500,
    "error": "Internal Server Error",
    "exception": "org.springframework.security.authentication.InsufficientAuthenticationException",
    "message": "User must be authenticated with Spring Security before authorization can be completed.",
    "path": "/oauth/authorize"
}

我试图将用户名和密码发送到 Basic Authentication HTTP headers POST 请求,但没用。
