Azure 移动服务错误 --- 请求无法完成。 ()

Question

我正在使用带有 .net 后端的 Azure 移动服务，以及使用基于 Xamarin Pcl 的解决方案的 MvvmCross。 当我从 Azure 移动服务提供的默认浏览器界面以交互方式运行该服务时，该服务会返回结果。我还使用离线数据同步功能。我可以将数据推送到服务器并且它可以工作，但是现在当我尝试从服务器提取数据时。

{Microsoft.WindowsAzure.MobileServices.MobileServiceInvalidOperationException: The request could not be completed.

我什至调试了从客户端到服务器的服务，结果出来了，但我不知道为什么会发生这种情况。我正在启用 Wifi 连接的 Windows Phone 8.1 设备上进行测试。

请帮忙。

进一步分析VS异常对话框中的http响应。实际错误是404 Not found。然后进一步调试问题发现Azure移动服务的应用程序url应该是https而不是http

如果产品团队能够发现这一点并给出正确的错误消息，那就太好了，这可以节省大量时间，而且开发人员也不会感到沮丧。
