<Run>推送通知概述</Run>
<LineBreak />
<LineBreak />
<Run>1、每个程序的推送通知 channel 只能有一个,每个设备最多只能有 30 个推送通知 channel</Run>
<LineBreak />
<Run>2、推送通知的 Http Header 最大 1 KB,内容最大 3 KB</Run>
<LineBreak />
<Run>3、对 web 服务做身份验证(即 https 协议),参考:http://msdn.microsoft.com/en-us/library/ff941099(v=vs.92)</Run>
<LineBreak />
<Run>4、对于已验证的 web 服务,MPNS 可以支持在设备转到活动状态或非活动状态时,回调指定的已验证的 web 服务,参考:http://msdn.microsoft.com/en-us/library/ff402554(v=vs.92)</Run>
</TextBlock>
</StackPanel> <!--
推送信息中需要编码的字符
< - &lt;

shell:SystemTray.IsVisible="True"> <StackPanel Orientation="Vertical">
<Button Name="btnRegister" Content="Get Channel Uri" Click="btnRegister_Click" />
<TextBox Name="txtUrl" />
<TextBlock Name="lblMsg" TextWrapping="Wrap" />
</StackPanel> </phone:PhoneApplicationPage>

PushToast.xaml.cs

/*
* 演示推送 Toast 通知(Toast 的显示时间大约是 10 秒)
*
* HttpNotificationChannel - 推送通知 channel
* HttpNotificationChannel.Find(string channelName) - 查找并返回 channel,一个 app 只能有一个 channel
*
* ChannelUri - 推送通知的 channel URI
* ChannelName - channel 的名称
* ConnectionStatus - channel 的连接状态,ChannelConnectionStatus.Connected 或 ChannelConnectionStatus.Disconnected
*
* ChannelUriUpdated - 获取到了 channel URI 后所触发的事件
* ErrorOccurred - 发生异常时所触发的事件
* ConnectionStatusChanged - 连接状态发生改变时所触发的事件
* ShellToastNotificationReceived - 程序运行中如果收到 Toast 是不会显示的,但是会触发此事件。
* 什么叫运行中:程序在前台显示,且调用了 HttpNotificationChannel.Find(channelName)(没有则创建一个),同时 channel 是在连接的状态
* HttpNotificationReceived - 接收到自定义信息通知后所触发的事件(仅在程序运行中才能接收到此信息)
*
* Open() - 打开 channel
* Close() - 关闭 channel
*
* BindToShellToast() - 将此 channel 绑定到 Toast 通知
* BindToShellTile() - 将此 channel 绑定到 Tile 通知,只能引用本地资源
* BindToShellTile(Collection<Uri> baseUri) - 将此 channel 绑定到 Tile 通知,允许引用远程资源(当使用远程图像时,不能是https,要小于80KB,必须30秒内下载完)
* baseUri - 允许引用的远程资源的域名集合(最大 256 个字符)
* IsShellToastBound - 此 channel 是否绑定到了 Toast 通知
* IsShellTileBound - 此 channel 是否绑定到了 Tile 通知
