ios - Azure 移动应用 Facebook 身份验证停止工作

Question

我使用 Azure 移动应用 和 .NET SDK 作为我的 iOS 应用的后端。通过 Facebook 完成身份验证。昨天，Facebook 的身份验证突然失败(后端或应用程序均未更改代码)。 iOS 客户端应用程序内的登录是通过

完成的

self.client?.login(withProvider:"facebook", token: ["access_token" : FBSDKAccessToken.current().tokenString] ){ (user, error) in }

通过调用此函数，我在客户端上得到以下结果。

Error Domain=com.Microsoft.MicrosoftAzureMobile.ErrorDomain Code=-1302 "You do not have permission to view this directory or page."

通过检查 Azure 移动应用 的流日志，我发现后端通过调用 Facebook Graph API 返回了 Unauthorized 401.71。

流媒体日志:

Microsoft.Azure.AppService.Authentication Verbose: 0 : Received request: POST https://XXXXXXXXXX.azurewebsites.net/.auth/login/facebook

Microsoft.Azure.AppService.Authentication Verbose: 0 : Calling into external HTTP endpoint GET https://graph.facebook.com/oauth/access_token.

我已经尝试在 Azure 中克隆移动应用程序并创建新的 Facebook 应用程序，但没有成功。
