一直坚持这个错误，直到疯狂阶段......请帮助
我创建了一个 Azure 移动服务 .NET 后端，现在正尝试从 Xamarin Android 客户端调用它的 Post 函数
我初始化并调用插入异步函数（这些只是我的代码片段）
private static IMobileServiceTable<Todo> _todoMobileServiceTable;
public static bool? InitializeAms()
{
try
{
CurrentPlatform.Init();
_mobileServiceClient = new MobileServiceClient(applicationUrl, applicationKey);
_todoMobileServiceTable = _mobileServiceClient.GetTable<Todo>();
return true;
}
catch (MalformedURLException malformedUrlException)
{
ReportHelper.Report(Tag, "There was an error creating the Mobile Service. Verify the URL", true, malformedUrlException);
}
catch (Exception exception)
{
ReportHelper.Report(Tag, "Error occurred during initialization of Azure Mobile Services", true, exception);
}
return null;
}
_todoMobileServiceTable.InsertAsync(Todo);
调用 .InsertAsync(Todo) 时出现以下错误
请求无法完成。（未找到）
注意：
Azure 存储客户端还不适用于 xamarin，我别无选择，只能使用这个 1 岁的脏叉子，它是为 iOS 而不是 Android 制作的（尽管它适用于 azure 移动服务 javascript）https:// github.com/zgramana/IOSAzureBlobUploader
如果我使用浏览器的“试用”按钮，它可以工作，但是当我从 xamarin 客户端应用程序调用它时它不起作用。
如果我使用 javascript 移动服务，它适用于 xamarin 客户端应用程序
本地 azure 移动服务和在线发布的都会出现此错误
