Error: The request could not be completed (Internal Server Error) on Azure Mobile Services
我正在构建一个 Windows 8.1 Metro 应用程序，它连接到托管在 Azure 上的服务器后端。现在，为了测试，当我点击应用程序屏幕上的按钮时，它会触发一个将值插入数据库的函数。
代码在这里：
private async void SubmitClick(object sender, RoutedEventArgs e)
{
Companies Quiblify = new Companies {Name = "CompanyX"};
await App.MobileService.GetTable<Companies>().InsertAsync(Quiblify);
}
}
当我 运行 这个应用程序并点击按钮时，我得到这个错误：
An exception of type 'Microsoft.WindowsAzure.MobileServices.MobileServiceInvalidOperationException' occurred in mscorlib.dll but was not handled in user code
Additional information: The request could not be completed. (Internal Server Error)
我的问题是什么？
编辑：这是服务器端代码。
// POST tables/Companies
public async Task<IHttpActionResult> PostCompany(Companies item)
{
Companies current = await InsertAsync(item);
return CreatedAtRoute("Tables", new { id = current.Id }, current);
}
这是错误日志：
Exception=System.Data.SqlClient.SqlException (0x80131904): Cannot open database "master" requested by the login. The login failed.

您正在连接到数据库的主架构，但连接字符串用户没有权限。您应该在门户中编辑 MS_TableConnectionString，或者创建一个新的连接字符串并使用该字符串。您还应该确保您使用的是正确的数据库模式。
