Azure AD，现场工程师示例，Azure移动服务无法在https://dugisapp2.azure-mobile.net/api/getFieldAgentDisplayName上进行授权

Question

我正在修改Field Engineer Sample Mobile App以使用我在Azure SQL Server中的数据。

我可以通过Postman访问我的所有数据，但是当我尝试启动应用程序以查找完成UI开发的错误时，我无法通过AAD移动服务身份验证。

我看到了类似的未回答的问题。这是我的具体细节。

Azure Mobile Service Error in its Log
Exception=Microsoft.IdentityModel.Clients.ActiveDirectory.ActiveDirectoryAuthenticationException: sts_token_request_failed: Token request to security token service failed. Check InnerException for more details ---> Microsoft.IdentityModel.Clients.ActiveDirectory.ActiveDirectoryAuthenticationException: AADSTS70002: Error validating credentials. AADSTS50012: Invalid client secret is provided.

Postman return from https://xxxxxapp2.azure-mobile.net/api/getFieldAgentDisplayName
{
  "message": "Authorization has been denied for this request."
}

Visual Studio 2013 error.
