Question

我是 windows phone 的新手。我正在开发一个应用程序。在这个应用程序中我想发送 pushnotifications。如何使用 c# 在 windows phone 8 中发送和接收 pushnotifications。请帮助我。

        {
            try
            {

                //string subscriptionUri = "http://db3.notify.live.net/throttledthirdparty/01.00/AwYAAACKB3Noan4l%2bojXM5%2f3TDodPTegXbZxtTAzRktj3eWFOYmjjN1FPIdkuduXrwYZByFKLxy1gXy8rCmf1FSM6GH92rva7ecbQ%2b1%2bnGYxLWxoAI0GL03fZbV29p%2fu%2fJYrHQI%3d";

                var sendNotificationRequest = (HttpWebRequest)WebRequest.Create(subscriptionUri);

                // Create an HTTPWebRequest that posts the toast notification to the Microsoft Push Notification Service.
                // HTTP POST is the only method allowed to send the notification.
                sendNotificationRequest.Method = "POST";

                // The optional custom header X-MessageID uniquely identifies a notification message. 
                // If it is present, the same value is returned in the notification response. It must be a string that contains a UUID.
                // sendNotificationRequest.Headers.Add("X-MessageID", "<UUID>");

                // Create the toast message.
                var toastMessage = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" +
                   "<wp:Notification xmlns:wp=\"WPNotification\">" +
                      "<wp:Toast>" +
                           "<wp:Text1>" + message + "</wp:Text1>" +
                      "</wp:Toast> " +
                   "</wp:Notification>";
                // Set the notification payload to send.
                byte[] notificationMessage = Encoding.Default.GetBytes(toastMessage);

                // Set the web request content length.
                sendNotificationRequest.ContentLength = notificationMessage.Length;
                sendNotificationRequest.ContentType = "text/xml";
                sendNotificationRequest.Headers.Add("X-WindowsPhone-Target", "toast");
                sendNotificationRequest.Headers.Add("X-NotificationClass", "2");


                using (var requestStream = sendNotificationRequest.GetRequestStream())
                {
                    requestStream.Write(notificationMessage, 0, notificationMessage.Length);
                }

                // Send the notification and get the response.
                var response = (HttpWebResponse)sendNotificationRequest.GetResponse();
                var notificationStatus = response.Headers["X-NotificationStatus"];
                var notificationChannelStatus = response.Headers["X-SubscriptionStatus"];
                var deviceConnectionStatus = response.Headers["X-DeviceConnectionStatus"];

                // Display the response from the Microsoft Push Notification Service.  
                // Normally, error handling code would be here. In the real world, because data connections are not always available,
                // notifications may need to be throttled back if the device cannot be reached.
                var rep = notificationStatus + " | " + deviceConnectionStatus + " | " + notificationChannelStatus;
                return rep;
            }
            catch (Exception ex)
            {
                return ex.ToString();
                // TextBoxResponse.Text = "Exception caught sending update: " + ex.ToString();
            }

这是我在 uri 上向该服务发送的服务，但我不知道何时响应它会抛出异常“远程服务器返回错误：（400）错误请求。”但我不知道是什么uri 的类型将给出。在此 uri 中发送一个密钥，但将发送哪种类型的密钥请任何人回复我

Answer 1

您可以查看PushSharp 它似乎已针对 Windows Phone 8 中的新通知负载格式进行了更新。Here 是用于从服务器发送推送通知的服务器代码，在此 link 您可以找到Windows Phone 的实现。

基本上，您的应用可能在 Windows Phone 8.1 中使用两种类型的推送通知。

1. MPNS: Microsoft Push Notification Service

2. WNS: Windows Notification Service.

MPNS 是在 Windows Phone 7 和 8 中使用的旧式通知服务。WNS 是 Windows 8 式通知，适用于专门针对 Windows Phone 8.1 的应用程序。 （Windows Phone Silverlight 8.1 应用和 Windows Phone 8.1（Windows 运行时）应用。

PushSharp 似乎支持两种类型的通知服务，PushSharp.WindowsPhone 库中的 MPNS 和 PushSharp.Windows 库中的 WNS。

同样值得一试 Azure。 这是相同的教程 => Send push notifications to authenticated users

以下是push notification for windows phone 所需的步骤。

1. 您的应用从推送客户端服务请求推送通知 URI。
2. Push 客户端服务与 Microsoft Push Notification Service (MPNS) 协商，MPNS 向 Push 客户端服务返回一个通知 URI。
3. Push 客户端服务将通知 URI 返回到您的应用程序。
4. 然后您的应用可以将通知 URI 发送到您的云服务。
5. 当您的云服务有信息要发送到您的应用时，它会使用通知 URI 向 MPNS 发送推送通知。
6. MPNS 将推送通知路由到您的应用。

请参阅this MSDN 页面以详细了解推送通知。

我尝试使用以下代码手动发送通知：

void SendToastMessage(string pushUri, string message)
        {
            HttpWebRequest request =
                (HttpWebRequest)WebRequest.Create(pushUri);
            request.ContentType = "text/xml";
            request.Method = "POST";
            request.Headers.Add("X-MessageID", Guid.NewGuid().ToString());
            request.Headers.Add("X-NotificationClass", "2");
            request.Headers.Add("X-WindowsPhone-Target", "toast");
            string toastMessage = @"<?xml version=""1.0"" encoding=""utf-8""?>
                          <wp:Notification
                              xmlns:wp=""WPNotification"">
                              <wp:Toast>
                                <wp:Text1>{0}</wp:Text1>
                                <wp:Text2>{1}</wp:Text2>
                              </wp:Toast>
                          </wp:Notification>";
            string toastXml = string.Format(toastMessage,
                                  "sample:",
                                  message);
            byte[] notificationMessage = Encoding.UTF8.GetBytes(toastXml);
            request.ContentLength = notificationMessage.Length;
            using (Stream requestStream = request.GetRequestStream())
            {
                requestStream.Write(notificationMessage,
                          0,
                          notificationMessage.Length);
            }
            try
            {
                HttpWebResponse response =
                (HttpWebResponse)request.GetResponse();

                return;
            }
            catch (Exception ex)
            {
                return;
            }
        }

一年前这段代码对我来说非常好用，现在仍然如此。但请确保您的 pushUri 正确。
