HttpWebRequest在Windows Phone 7上返回「遠程服務器返回錯誤：NotFound」

我正在嘗試使用Windows Phone 7仿真器對Huddle API進行身份驗證。但是，我沒有取得任何成功。我不斷收到「遠程服務器返回錯誤：NotFound」。我甚至嘗試過「貶低」我的代碼，只是嘗試一個直接的網站，例如。谷歌，但仍然得到相同的結果。HttpWebRequest在Windows Phone 7上返回「遠程服務器返回錯誤：NotFound」

我有以下代碼：

string url = "http://www.google.com"; 

HttpWebRequest client= WebRequest.CreateHttp(new Uri(url)) as HttpWebRequest; 

client.AllowReadStreamBuffering = true; 

// Call and handle the response. 
client.BeginGetResponse(
    (asResult) => 
    { 
    Dispatcher.BeginInvoke(
    () => 
    { 
    try 
    { 
     var response = client.EndGetResponse(asResult); 
     System.IO.StreamReader reader = new System.IO.StreamReader(response.GetResponseStream()); 
     string responseString = reader.ReadToEnd(); 

    } 
    catch (WebException failure) 
    { 
     throw failure; 
    } 
    }); 
    }, 
    null 
);

執行總是在閉鎖段結束。然而，在觀看Fiddler2之後，google.com似乎沒有任何流量。所以這個請求似乎沒有被做出來。

我在這裏看到過類似的問題Retrieve XML from https using WebClient/HttpWebRequest - WP7，但我使用的是標準端口，所以不確定這是相關的。我也嘗試按照帖子簡化代碼，但沒有成功。

有趣的是，最可能的選擇似乎是因爲我可能沒有我的AppManifestWM.xaml文件按HttpWebRequest Breaks On WP7定義網絡功能，但我AppManifestWM.xaml文件似乎有這樣的定義：

     </TemplateType5> 
     </PrimaryToken> 
    </Tokens> 
    </App> 
</Deployment>

所以我很茫然。該請求實際上並沒有發生，導致我認爲東西正在阻止它。

更新：

沒有什麼改變，但認爲該堆棧跟蹤可能HEKO：

System.Net.WebException was unhandled Message=The remote server returned an error: NotFound.

狀態是System.Net.WebExceptionStatus.UnknownError

感謝您的時間。

好吧，我已經解決了它......但不知道怎麼辦。我的機器沒有重新啓動，我的代碼沒有改變。唯一可能的解釋是我的模擬器確實崩潰了幾次。也許在那裏。

感謝您的時間，這是我使用的代碼，這與跨欄API效果很好：你已經提琴手運行

   string url = "https://api.huddle.net/v1/xml/workspaces"; ; 

       HttpWebRequest client= WebRequest.CreateHttp(new Uri(url)) as HttpWebRequest; 

       client.Credentials = new NetworkCredential(ViewModel.UserAccount.UserName, ViewModel.UserAccount.Password); 
       client.AllowReadStreamBuffering = true; 

       // Call and handle the response. 
       client.BeginGetResponse(
        (asResult) => 
        { 
         Dispatcher.BeginInvoke(
          () => 
          { 
           try 
           { 
            var response = client.EndGetResponse(asResult); 
            System.IO.StreamReader reader = new System.IO.StreamReader(response.GetResponseStream()); 
            string responseString = reader.ReadToEnd(); 



                     } 
           catch (WebException failure) 
           { 
            MessageBox.Show(failure.Message, "Cannot authenticate", MessageBoxButton.OK); 
#if DEBUG 
            throw failure; 
#endif 
           } 
          }); 
        }, 
         null 
       );
