MobileServiceInvalidOperationException当试图检索数据从Azure的 [英] MobileServiceInvalidOperationException When Trying To Retrieve Data From Azure

问题描述

这是我使用的方法。

try
{
    List<Patient> pList = await App.MobileService.GetTable<Patient>().Where(
                patient => patient.id == 1).ToListAsync();
    foreach (Patient p in pList)
    {
        System.Diagnostics.Debug.WriteLine("{0}, {1}", p.id, p.first_name);
    }
}
catch (Exception err)
{
    System.Diagnostics.Debug.WriteLine("ERROR! : {0}", err.Message);
}

下面是病人实体。

class Patient
{
    public int id { get; set; }
    public string first_name { get; set; }
    public string last_name { get; set; }
    public string middle_name { get; set; }
    public string nirc { get; set; }
    public int bed_id { get; set; }
}

下面就是我得到的错误。

Here's the error i am getting.

An exception of type 'System.Net.WebException' occurred in System.Windows.ni.dll and     wasn't handled before a managed/native boundary

当我一个TryCatch内缠上了我的方法，我得到这个消息

When i wrap my method within a TryCatch, i get this message

Error : The request could not be completed.  ()

下面是堆栈错误信息

有几点要注意。

1. 权限设置为任何人只要有应用中的关键


2. 我添加引用的Windows Azure移动服务管理客户端


3. 我已经插在App.XAML.CS.此code 使用Microsoft.WindowsAzure.MobileServices;


4. 我已经放在这块code从<一收购href=\"http://www.windowsazure.com/en-us/develop/mobile/tutorials/get-started-with-data-dotnet/\">this App.XAML.CS.结果中的网站
   公共静态MobileServiceClient MobileService =新MobileServiceClient（AppUrl，的AppKey）;

1. Permission is set to Anybody with the Application Key
2. I've added reference to Windows Azure Mobile Services Managed Client
3. I've already inserted this code within App.XAML.CS. using Microsoft.WindowsAzure.MobileServices;
4. I've already placed this piece of code acquired from this website within App.XAML.CS.
   public static MobileServiceClient MobileService = new MobileServiceClient( AppUrl, AppKey );

为什么我无法连接到我的数据库？我试着运行这些codeS在Windows商店应用程序和它的工作。 previously我已经做了完全一样的东西和它的工作为好。

Why am i unable to connect to my database? I've tried running these codes on a Windows Store Application and it worked. Previously i've done the exact same thing and it worked as well.

推荐答案

的 这 链接救了我。

This link saved me.

显然，所有我做的是从 HTTPS 服务地址更改为 HTTP 。因此，而不是这个，

Apparently, all i had to do is to change the service address from https to http. So instead of this,

public static MobileServiceClient MobileService = new MobileServiceClient( 
    "https://www.example.azure-mobile.net/", 
    "fjkdslajkfdlsref31321fgdsat34ajklfdslajfkldsa" 
);

将其更改为

public static MobileServiceClient MobileService = new MobileServiceClient( 
    "http://www.example.azure-mobile.net/", 
    "fjkdslajkfdlsref31321fgdsat34ajklfdslajfkldsa" 
);

问题解决了。
