首先是用java来实现简单的Server端(http的请求内容格式可以参考msdn:http://msdn.microsoft.com/zh-cn/library/hh202945(v=vs.92)):

	/**
	 * 推送toast通知
	 * @param uriString 推送服务通知uri
	 * @param title     toast标题
	 * @param content   toast内容
	 * @param param     页面跳转参数
	 * @return          推送通知服务响应码
	 * @throws IOException
	 */
	public static int pushToastNotifications(String uriString, String title, String content, String param) throws IOException{
		
		String toastMsg = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" +
                "<wp:Notification xmlns:wp=\"WPNotification\">" +
                "<wp:Toast>" +
                "<wp:Text1>" + title + "</wp:Text1>" +
                "<wp:Text2>" + content + "</wp:Text2>" +
                "<wp:Param>"+ param +"</wp:Param>" +
                "</wp:Toast>" +
                "</wp:Notification>";	
		
		URL url = null;
		HttpURLConnection http = null;
		
		try{
			url = new URL(uriString);
			http = (HttpURLConnection)url.openConnection();
			http.setDoOutput(true);
			http.setRequestMethod("POST");
			http.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
			http.setRequestProperty("X-WindowsPhone-Target", "toast");
			http.setRequestProperty("X-NotificationClass", "2");
			http.setRequestProperty("Content-Length", "1024");
			http.getOutputStream().write(toastMsg.getBytes());
			// 刷新对象输出流，将任何字节都写入潜在的流中
			http.getOutputStream().flush();
			// 关闭输出流
			http.getOutputStream().close();			
		}
		catch(Exception e) {
			e.printStackTrace();
		}
		finally{
			if(http != null){
				http.disconnect();
			}
		}	
		
		return http.getResponseCode();							
	}

服务端的测试数据:

	public static void main(String[] args) {
		// TODO Auto-generated method stub		
		
		try {
			System.in.read();
		} catch (IOException e1) {
			// TODO Auto-generated catch block
			e1.printStackTrace();
		}
		// 该uri是客户端运行并创建通道之后获得的	
		String urls = "http://db3.notify.live.net/throttledthirdparty/01.00/AAHGO5Q4sO3ZQa1cBCWwx4X9AgAAAAADAQAAAAQUZm52OjIzOEQ2NDJDRkI5MEVFMEQ";
		String text1 = "中文";
		String text2 = "English";
		String param = "/NotificationPage.xaml?NavigatedFrom = ToastNotification&amp;uri=http://baike.baidu.com/";  // 推送负载中，& 要转换写为&amp;
		
		try {
			int code = pushToastNotifications(urls, text1, text2, param);
			System.out.println("Response code : "+code);
		} 
		catch (IOException e) {
			e.printStackTrace();
		}
	}

接着是手机客户端的消息接收模块：

这里主要是为了演示当程序不在前台运行时Toast消息到达并点击Toast，来实现跳转到指定页面的效果。在客户端程序中本次demo会实现两个页面：MainPage.xaml和NotificationPage.xaml；MainPage.xaml用于获得通道uri，NotificationPage.xaml用于实现接收Toast时的指定跳转页面。

</phone:PhoneApplicationPage>

b. NotificationPage.xaml.cs

using System;
using Microsoft.Phone.Controls;

namespace PushNotificationDemo
{
    public partial class NotificationPage : PhoneApplicationPage
    {
        #region Constants

        private const string DefaultUrl = "http://www.baidu.com/";
        private string m_UriString = string.Empty;

        #endregion

        public NotificationPage()
        {
            InitializeComponent();

            Browser.Navigate(new Uri(DefaultUrl));
        }

        protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
        {
            base.OnNavigatedTo(e);

            try
            {
                m_UriString = NavigationContext.QueryString["uri"];
                Browser.Navigate(new Uri(m_UriString));
            }
            catch
            {
            }
        }

        private void OnScriptNotify(object sedner, NotifyEventArgs args)
        {
        }
    }
}

最后就是实验证明了。运行的效果图如下:
