我爲什麼不能WNS發送Toast通知從C＃到Windows Phone 8.1

Question

我按照這兩個指南： https://msdn.microsoft.com/en-us/library/windows/apps/hh202945(v=vs.105).aspx https://msdn.microsoft.com/library/windows/apps/xaml/hh868252

生成的代碼如下。儘管它看起來都很正確，但它會返回404錯誤。怎麼會這樣？任何幫助都會延誤我的自殺。

public static void PushToWindows2() 
    { 
     try 
     { 
      var accessToken = GetAccessToken("Nhz******************XkwX", "ms-app://s-1-15-2-***************-2150981501"); 

      byte[] contentInBytes = Encoding.UTF8.GetBytes("<toast launch=\"\"><visual lang=\"en-US\"><binding template=\"ToastImageAndText01\"><image id=\"1\" src=\"World\" /><text id=\"1\">Hello</text></binding></visual></toast>"); 

      HttpWebRequest request = HttpWebRequest.Create("https://db5.notify.windows.com/?token=awyaaaborhlhub%2bfxeytzjnz****************pftroh5l18sgorvgrkq%3d") as HttpWebRequest; 
      request.Method = "POST"; 
      request.ContentLength = contentInBytes.Length; 
      request.ContentType= "text/xml"; 
      request.Headers.Add("X-WindowsPhone-Target", "token"); 
      request.Headers.Add("X-NotificationClass", "1"); ; 
      request.Headers.Add("X-WNS-Type", "wns/toast"); 
      request.Headers.Add("Authorization", String.Format("Bearer {0}", accessToken.AccessToken.ToString())); 


      using (Stream requestStream = request.GetRequestStream()) 
       requestStream.Write(contentInBytes, 0, contentInBytes.Length); 

      HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
      string notificationStatus = response.Headers["X-NotificationStatus"]; 
      string notificationChannelStatus = response.Headers["X-SubscriptionStatus"]; 
      string deviceConnectionStatus = response.Headers["X-DeviceConnectionStatus"]; 
     } 
     catch (Exception ex) 
     { 
      Console.Write("EXCEPTION: " + ex.Message); 
     } 
    } 
    [DataContract] 
    public class OAuthToken 
    { 
     [DataMember(Name = "access_token")] 
     public string AccessToken { get; set; } 
     [DataMember(Name = "token_type")] 
     public string TokenType { get; set; } 
    } 

    public static OAuthToken GetOAuthTokenFromJson(string jsonString) 
    { 
     using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(jsonString))) 
     { 
      var ser = new DataContractJsonSerializer(typeof(OAuthToken)); 
      var oAuthToken = (OAuthToken)ser.ReadObject(ms); 
      return oAuthToken; 
     } 
    } 

    public static OAuthToken GetAccessToken(string secret, string sid) 
    { 
     var urlEncodedSecret = HttpUtility.UrlEncode(secret); 
     var urlEncodedSid = HttpUtility.UrlEncode(sid); 

     var body = String.Format("grant_type=client_credentials&client_id={0}&client_secret={1}&scope=notify.windows.com", 
           urlEncodedSid, 
           urlEncodedSecret); 

     string response; 
     using (var client = new WebClient()) 
     { 
      client.Headers.Add("Content-Type", "application/x-www-form-urlencoded"); 
      response = client.UploadString("https://login.live.com/accesstoken.srf", body); 
     } 
     return GetOAuthTokenFromJson(response); 
    } 

我也嘗試去PushSharp路由，在這種情況下，我得到「設備訂閱已過期」錯誤。這裏所說：

var config = new WnsConfiguration("424****.*******nts", "ms-app://s-1-15-2-***************1501", "Nhz************XkwX"); 
     // Create a new broker 
     var wnsBroker = new WnsServiceBroker (config); 
     wnsBroker.QueueNotification(new WnsToastNotification { 
       ChannelUri = deviceId, 
       Payload = XElement.Parse (@" 
        <toast> 
         <visual> 
          <binding template=""ToastText01""> 
           <text id=""1"">WNS_Send_Single</text> 
          </binding> 
         </visual> 
        </toast>") 
     }); 
    } 

更新：

它不編碼相關的任何。我使用了帶有=和+號的未編碼標記和編碼標記。仍然404

WNS的HTTP 404錯誤意味着通道URI本身已被消除，因此WNS無法理解它。它看起來像你的代碼中的通道URI在某處得到了tolower（），通常這些token以「AwYAAAD」開頭。嘗試刪除降低頻道URI的內容。

此外，當你想要WNS（雖然這不會導致你的404錯誤），它看起來像是混合了WNS和MSDN文檔。 This是WNS，但this是MPNS文檔。具體地，這些頭對於MPNS和將由WNS被忽略或失敗：

• X-WindowsPhone的-目標
• X-NotificationClass
• X-NotificationStatus
• X-SubscriptionStatus
• X- DeviceConnectionStatus

您想要使用these WNS標頭。
