Windows Phone7开发之 Push+Notification

     <p style="text-indent:-21pt;margin:0cm 0cm 0pt 21pt;"><span style="line-height:19px;">一．</span><span style="line-height:19px;font-family:宋体;">简介</span></p>    <p style="text-indent:0px;margin:0cm 0cm 0pt 21pt;">Push Notification <span style="line-height:19px;font-family:宋体;">是</span>windows phone 7<span style="line-height:19px;font-family:宋体;">中的特色功能之一，这个功能可以变相的让普通开发者实现多任务（尽管并不是真正的多任务）。它为手机端应用和</span>webservice<span style="line-height:19px;font-family:宋体;">之间建立了一条专用的、持久的、稳定的通道来推送通知。当通道建立后，手机端应用可以接收</span>webservice<span style="line-height:19px;font-family:宋体;">的任何信息。</span></p>    <p style="text-indent:0px;margin:0cm 0cm 0pt 21pt;"></p>    <p style="text-indent:-21pt;margin:0cm 0cm 0pt 21pt;"><span style="line-height:19px;">二．</span><span style="line-height:19px;font-family:宋体;">分类</span></p>    <p style="text-indent:0px;margin:0cm 0cm 0pt 21pt;"><span style="line-height:19px;font-family:宋体;">对于</span>Push Notification<span style="line-height:19px;font-family:宋体;">主要有三种：</span></p>    <p style="text-indent:-18pt;margin:0cm 0cm 0pt 39pt;"><span style="line-height:19px;">1.<span style="font:7pt 'Times New Roman';">       </span></span>Tile Notification:</p>    <p style="text-indent:0px;margin:0cm 0cm 0pt 39pt;"><span style="line-height:19px;font-family:宋体;">是可以改变</span>Quick Lanuch area<span style="line-height:19px;font-family:宋体;">内的图标内容（图片，文字等）的方式。不过这个需要把程序</span>pin to start,<span style="line-height:19px;font-family:宋体;">才可以使用。</span></p>    <p style="text-indent:-18pt;margin:0cm 0cm 0pt 39pt;"><span style="line-height:19px;">2.<span style="font:7pt 'Times New Roman';">       </span></span>Toast Notification:</p>    <p style="text-indent:0px;margin:0cm 0cm 0pt 39pt;"><span style="line-height:19px;font-family:宋体;">是在屏幕上面可以显示一个提示栏的方式。当点击提示栏可以打开应用程序。</span></p>    <p style="text-indent:-18pt;margin:0cm 0cm 0pt 39pt;"><span style="line-height:19px;">3.<span style="font:7pt 'Times New Roman';">       </span></span>Raw Notification:</p>    <p style="text-indent:0px;margin:0cm 0cm 0pt 39pt;"><span style="line-height:19px;font-family:宋体;">是直接使用</span>Http<span style="line-height:19px;font-family:宋体;">方式来接收（</span>http polling<span style="line-height:19px;font-family:宋体;">）通知的方式。并且是不可见的，以后台方式传送通知。</span></p>    <p style="text-indent:0px;margin:0cm 0cm 0pt 39pt;"><span style="line-height:19px;font-family:宋体;">对于以上几种通知，都需要一个服务端以</span>push notification<span style="line-height:19px;font-family:宋体;">方式来发送通知，</span> <span style="line-height:19px;font-family:宋体;">也就是说要使用</span>push notification<span style="line-height:19px;font-family:宋体;">都需要一个服务端。</span></p>    <p style="text-indent:-21pt;margin:0cm 0cm 0pt 21pt;"><span style="line-height:19px;">三．</span><span style="line-height:19px;font-family:宋体;">创建服务器端</span></p>    <p style="text-indent:0px;margin:0cm 0cm 0pt 21pt;"><span style="line-height:19px;font-family:宋体;">对于服务器端来说，发送不同的通知，都是以</span>Http<span style="line-height:19px;font-family:宋体;">方式发出去的，但是在发送时，需要配置相应的参数，来告诉</span>Push Notification Service<span style="line-height:19px;font-family:宋体;">所发送的类型是什么。</span></p>    <p style="text-align:left;text-indent:21pt;margin:5px auto;" align="left"><span
