推送通知没有进入Windows Phone应用程序8.1RT？

Question

我正在开发发送推送通知，一切正常，响应也“正常”。但我无法得到任何通知。我的设备设置有任何变化吗？请帮帮我。

以下是我的代码：

我从这段代码获得channeluri：

 var channel = await PushNotificationChannelManager.CreatePushNotificationChannelForApplicationAsync();
 var jj = channel.Uri.ToString();

我的服务代码是：

string subscriptionUri = "https://hk2.notify.windows.com/?token=rretetretretretretretrergtrgtrgtrg43589743cn43jr43jr43jr4rvr43ro045jv77nninuoinjyt";

string PushNotificationXML = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" +
                             "<wp:Notification xmlns:wp=\"WPNotification\">" +
                             "<wp:Tile>" + "<wp:BackgroundImage>" + "sdfsafdsafsdf" +
                             "</wp:BackgroundImage>" + "<wp:Count>" + 
                             "0" + "</wp:Count>" + "<wp:Title>" +
                             "Hi This is pavan" + "</wp:Title>" +
                             "</wp:Tile> " + "</wp:Notification>";

string strChannelURI = subscriptionUri;

//string secret = "xxxxxxxxxxxxxxxxx";
//string sid = "ms-app://s-1-15-2-23454435445-4343434-4343434443434-343434343-334-343443434-3434344443";
var accessToken = GetAccessToken(secret, sid);

byte[] contentInBytes = Encoding.UTF8.GetBytes(PushNotificationXML);

HttpWebRequest request = HttpWebRequest.Create(subscriptionUri) as HttpWebRequest;
request.Method = "POST";
request.Headers.Add("X-WNS-Type", "wns/badge");
request.ContentType = "text/xml";
request.Headers.Add("Authorization", String.Format("Bearer {0}", accessToken.AccessToken));

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

using (HttpWebResponse webResponse = (HttpWebResponse)request.GetResponse())
    webResponse.StatusCode.ToString();

响应“正常”，但我无法收到有关我设备的任何通知。
