APNS 推送通知服务器返回抑制作为通知状态

Question

我正在尝试将推送通知发送到我的寡妇手机 8 应用程序（平铺通知）。这是来自 MPNS 的响应：通知状态：抑制 notificationChannelStatus :Active, deviceConnectionStatus:Connected。我查看了服务器响应码，发现如下解释：

Push 收到并删除了推送通知 通知服务。如果 通过调用 BindToShellTile 或未启用通知类型 客户端应用程序中的 BindToShellToast

这是我在客户端的代码，我正在调用 BindToShellTile 方法 - 它在第一次安装应用程序时被调用。

HttpNotificationChannel pushChannel;
string channelName = "TileSampleChannel";
pushChannel = HttpNotificationChannel.Find(channelName);
if (pushChannel == null) {
    pushChannel = new HttpNotificationChannel(channelName);
    // Register for all the events before attempting to open the channel.
    pushChannel.ChannelUriUpdated += new EventHandler<NotificationChannelUriEventArgs>(PushChannel_ChannelUriUpdated);
    pushChannel.ErrorOccurred += new EventHandler<NotificationChannelErrorEventArgs>(PushChannel_ErrorOccurred);  
    pushChannel.Open();               
    pushChannel.BindToShellTile();
} else {          
    pushChannel.ChannelUriUpdated += new EventHandler<NotificationChannelUriEventArgs>(PushChannel_ChannelUriUpdated);
    pushChannel.ErrorOccurred += new EventHandler<NotificationChannelErrorEventArgs>(PushChannel_ErrorOccurred);                    
    System.Diagnostics.Debug.WriteLine(pushChannel.ChannelUri.ToString());
    MessageBox.Show(String.Format("Channel Uri is {0}",
    pushChannel.ChannelUri.ToString())); 
}

而且我能够成功获取频道 URI。为什么我总是处于抑制状态？我已经在设备上对此进行了测试，并且检查了电池电量是否不足。磁贴也固定在开始屏幕上。

这是我的 XML

 string tileMessage = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" +
                "<wp:Notification xmlns:wp=\"WPNotification\">" +
                    "<wp:Tile>" +
                      "<wp:BackgroundImage>" + TextBoxBackgroundImage.Text + "</wp:BackgroundImage>" +
                      "<wp:Count>" + TextBoxCount.Text + "</wp:Count>" +
                      "<wp:Title>" + TextBoxTitle.Text + "</wp:Title>" +
                      "<wp:BackBackgroundImage>" + TextBoxBackBackgroundImage.Text + "</wp:BackBackgroundImage>" +
                      "<wp:BackTitle>" + TextBoxBackTitle.Text + "</wp:BackTitle>" +
                      "<wp:BackContent>" + TextBoxBackContent.Text + "</wp:BackContent>" +
                   "</wp:Tile> " +
                "</wp:Notification>";

Answer 1

验证您的通知内容长度、内容类型和标题是否正确。

对于 Tile 通知，您需要以下标题：

sendNotificationRequest.Headers.Add("X-WindowsPhone-Target", "token");
sendNotificationRequest.Headers.Add("X-NotificationClass", "1");

在标题之前，设置内容长度和类型如下：

sendNotificationRequest.ContentLength = notificationMessage.Length;
sendNotificationRequest.ContentType = "text/xml";

如果您没有正确指定可以将通知状态设置为已抑制的标题。这可能很有用。
