wp8:在应用程序处于背景状态时处理Toast通知 [英] wp8:Handle Toast notification when application is in backgroung

问题描述

我的应用程序正在运行时，我可以在ShellToastNotificationReceived(对象发送者，NotificationEventArgs e)事件处理程序上接收烤面包通知，作为e.Collection中的键.

While my app is running I can receive toast notification,on ShellToastNotificationReceived(object sender, NotificationEventArgs e) event handler as keys in e.Collection.

如果我的应用程序未运行并且有敬酒通知到达，则显示敬酒，但是我该如何处理该通知?

If my app is not running and a toast notification arrives, a toast is displayed but how i can i handle this notification?

我的意思是当我的应用程序未运行且通知到达时，哪个事件着火.

I mean which event is fire when my application is not running and notification arrives.

我认识后台代理，但不能满足我的要求

I know background agent but its not fulfill my requirement

谢谢.

推荐答案

Windows Phone平台负责处理Push Notifications，并且当应用程序未运行时，开发人员无权直接进行通知处理.这意味着在收到Toast之后，您将无法执行任何后台逻辑.但是，当Toast消息包含<wp:Param>值和Uri到特定的应用页面时，如果用户点击Toast弹出窗口，则用户将被重定向到该页面.因此，您可以在用户点击Toast弹出窗口之后执行特定的工作.为此，您需要在Uri中添加一个参数，例如/YourPage?IsToast=true，并覆盖页面的OnNavigatedTo方法以运行业务逻辑:

Windows Phone platform is responsible to handle Push Notifications and developers don't have a direct access for notification handling when an app is not running. That means you can't do any background logic after Toast is received. But when Toast message contains <wp:Param> value with an Uri to a specific app page then user will be redirected to this page, if user taps a Toast popup. So, you can do specific job after user tapped a Toast popup. To accomplish it, you need add an parameter to Uri, for example /YourPage?IsToast=true and override OnNavigatedTo method of the page to run your business logic:

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

            if (NavigationContext.QueryString.ContainsKey("IsToast"))
            {
                //do your business here
            }
    }

在其他情况下，您需要使用后台工作者.

For other cases you need to use a background worker.
