Question

我正在尝试在WP7.1中使用推送通知。我创建了类和一些php类。该示例适用于所有通知类型，但我的问题是UriChannel。在我的简单示例中，我必须在php代码中手动编写URI通道。

uri频道对于我的应用安装的所有设备都是唯一的吗？
如何将Uri频道发送到我的服务器？

感谢。

这是我的代码：

/// Holds the push channel that is created or found.
    HttpNotificationChannel pushChannel;
    // The name of our push channel.
    string channelName = "LiveTileChannel";

    // Costruttore
    public MainPage()
    {
        InitializeComponent();
        CreatePushChannel();
    }

    private void CreatePushChannel()
    {
        // Try to find the push channel.
        pushChannel = HttpNotificationChannel.Find(channelName);

        // If the channel was not found, then create a new connection to the push service.
        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.ShellToastNotificationReceived += new EventHandler<NotificationEventArgs>(PushChannel_ShellToastNotificationReceived);
            pushChannel.HttpNotificationReceived += new EventHandler<HttpNotificationEventArgs>(pushChannel_HttpNotificationReceived);
            pushChannel.Open();
            // Bind this new channel for Tile events.
            pushChannel.BindToShellTile();
            pushChannel.BindToShellToast();
            connessioneTxt.Text = "Connessione avvenuta";
        }
        else
        {
            // The channel was already open, so just register for all the events.
            pushChannel.ChannelUriUpdated += new EventHandler<NotificationChannelUriEventArgs>(PushChannel_ChannelUriUpdated);
            pushChannel.ErrorOccurred += new EventHandler<NotificationChannelErrorEventArgs>(PushChannel_ErrorOccurred);
            pushChannel.ShellToastNotificationReceived += new EventHandler<NotificationEventArgs>(PushChannel_ShellToastNotificationReceived);
            pushChannel.HttpNotificationReceived += new EventHandler<HttpNotificationEventArgs>(pushChannel_HttpNotificationReceived);
            // Display the URI for testing purposes. Normally, the URI would be passed back to your web service at this point.
            System.Diagnostics.Debug.WriteLine(pushChannel.ChannelUri.ToString());
            uriTxt.Text=pushChannel.ChannelUri.ToString();
            connessioneTxt.Text = "Connessione già avvenuta";
        }
    }

    void pushChannel_HttpNotificationReceived(object sender, HttpNotificationEventArgs e)
    {
        string message;

        using (System.IO.StreamReader reader = new System.IO.StreamReader(e.Notification.Body))
        {
            message = reader.ReadToEnd();
        }

        Dispatcher.BeginInvoke(() => rawTxt.Text = String.Format("Received Notification {0}:\n{1}",
                DateTime.Now.ToShortTimeString(), message)
                );

    }

    /// Event handler for when the Push Channel Uri changes.     
    void PushChannel_ChannelUriUpdated(object sender, NotificationChannelUriEventArgs e)
    {

        Dispatcher.BeginInvoke(() =>
        {
            // Display the new URI for testing purposes. Normally, the URI would be passed back to your web service at this point.
            System.Diagnostics.Debug.WriteLine(e.ChannelUri.ToString());
            uriTxt.Text = pushChannel.ChannelUri.ToString();
        });
    }

    // Event handler for when a Push Notification error occurs.   
    void PushChannel_ErrorOccurred(object sender, NotificationChannelErrorEventArgs e)
    {
        // Error handling logic for your particular application would be here.
        Dispatcher.BeginInvoke(() =>
            MessageBox.Show(String.Format("A push notification {0} error occurred.  {1} ({2}) {3}", e.ErrorType, e.Message, e.ErrorCode, e.ErrorAdditionalData)));
    }

    void PushChannel_ShellToastNotificationReceived(object sender, NotificationEventArgs e)
    {
        System.Diagnostics.Debug.WriteLine("notifica aperta");
    }


}

URI通道对于安装应用程序的每个设备都是唯一的。它必须对每个设备都是唯一的，因为这是告诉MPN服务向哪个设备发送通知的内容。它与Apple推送通知的设备令牌和Google Cloud Messaging的注册ID具有相同的用途。

您可以通过向服务器发送一些HTTP GET或POST请求将URI通道发送到您的服务器，并将URI Chnnael作为输入参数。

以下是从MSDN获取服务器的一些指导原则：

每次您的应用启动时，都应该从推送中传递URI   通道发送推送通知的云服务。它   还建议您将设备ID传递给云服务   这样云服务就可以跟踪URI所在的设备   分配。如果URI发生更改，则云服务可以替换旧服务   该设备ID的URI。 Windows Phone不提供框架   这样做，因为在大多数情况下，应用程序和云服务已经拥有   他们自己用来相互沟通的协议。

与云服务通信的最佳做法包括：

应用应通过相应的云服务进行身份验证。

应用程序应在将URI发送到其之前加密其通知通道URI   相应的云服务。

如果您的云服务将使用Windows中不存在的通知属性   然后，您应该将操作系统版本信息传递给您的云服务   云服务可以正确降级Windows Phone OS 7.0的通知   客户端。

云服务应验证从其收到的通知通道URI   相应的应用程序并以安全的方式存储它。

从应用程序启动会话时，应始终发送通知通道URI   到相应的云服务。

云服务应该有一个状态代码，可以发送到相应的应用程序   将触发应用程序创建新的通知渠道URI。
