我的问题有点不寻常，我正在努力创建一个自定义的@RestController，每次为我的应用程序启动一个不同范围的OAuth2登录过程？
更具体地说，我有一个这样的示例配置：

spring:
  security:
    oauth2:
      client:
        registration:
          my-client:
            clientId: client1
            clientSecret: some-password
            // Basic the property `scope` is not provided here, but in the controller
        provider:
          my-client:
            authorizationUri: https://somehost.com/oauth
            userInfoUri: https://somehost.com/data
            tokenUri: https://somehost.com/oauth/token
            redirectUri: https://somehost.com/oauth
            authorizationGrantType: authorization_code
            clientAuthenticationMethod: client_secret_post

我想要创建的是一个API端点，它充当代理端点，根据提供的scope将用户移动到登录页面。

@GetMapping(path="/redirect-to-login")
public ResponseEntity<?> proxyLogin(@RequestParam("scope") final String scope) {
 log.info("Received scope: {}", scope);
 // TODO: What needs to happen here, is that I need to generate a new login here
 // TODO: for the requested OAuth2 Client scope and redirect the user to the login page of
 // TODO: the provider with the scope.
}

我尝试接收OAuth2ClientRegistrationRepository的所有客户端注册，并尝试扩展它以提供该范围，但我无法弄清楚。
