Windows Phone应用程序未收到来自Parse.com的推送通知

Question

我已经学习了这篇关于在Windows Phone应用程序中设置解析推送通知的教程。这是我的代码：

public App() {
  // Global handler for uncaught exceptions.
  UnhandledException += Application_UnhandledException;

  // Standard XAML initialization
  InitializeComponent();

  // Phone-specific initialization
  InitializePhoneApplication();

  // Language display initialization
  InitializeLanguage();

  // Show graphics profiling information while debugging.
  if (Debugger.IsAttached) {
    // Display the current frame rate counters.
    Application.Current.Host.Settings.EnableFrameRateCounter = true;

    // Show the areas of the app that are being redrawn in each frame.
    //Application.Current.Host.Settings.EnableRedrawRegions = true;

    // Enable non-production analysis visualization mode,
    // which shows areas of a page that are handed off to GPU with a colored overlay.
    //Application.Current.Host.Settings.EnableCacheVisualization = true;

    // Prevent the screen from turning off while under the debugger by disabling
    // the application's idle detection.
    // Caution:- Use this under debug mode only. Application that disables user idle detection will continue to run
    // and consume battery power when the user is not using the phone.
    PhoneApplicationService.Current.UserIdleDetectionMode = IdleDetectionMode.Disabled;
  }

  // Initialize the Parse client with your Application ID and .NET Key found on
  // your Parse dashboard

  ParseClient.Initialize("grpTmrClet8K35yeXg2HQKK8wl59VeC9ijH0I0dn", "os8EfSFq9maPBtDJ91Mq0xnWme8fLANhttTPAqKu");
  // After calling ParseClient.Initialize():
  this.Startup += async (sender, args) =>
  {
      // This optional line tracks statistics around app opens, including push effectiveness:
      ParseAnalytics.TrackAppOpens(RootFrame);

      // By convention, the empty string is considered a "Broadcast" channel
      // Note that we had to add "async" to the definition to use the await keyword
      await ParsePush.SubscribeAsync("testchannel");
  };


}

// Code to execute when the application is launching (eg, from Start)
// This code will not execute when the application is reactivated
private async void Application_Launching(object sender, LaunchingEventArgs e) {
    await ParseAnalytics.TrackAppOpenedAsync();
}

当我从Parse dashboard发送推送通知时，它不会被接收到。我试着在模拟器（Windows Phone 8.0）和设备（8.1）上运行，在前景、背景和关闭应用程序时，结果都是相同的。

当我使用像上面的“testchannel”这样的通道并使用segment选项时，通道名称会出现在选项的下拉列表中，表明应用程序至少正在连接Parse，但它只是不会接收通知。

希望有人能帮我找出我所缺少的东西。提前道谢。

如果您正在开发Windows Phone8.1应用程序，请确保您在清单文件中启用了toast通知。我还不是很了解关于解析的一切，但这对我来说是可行的。

在app.xaml.cs中：

public App()
    {
        this.InitializeComponent();
        this.Suspending += this.OnSuspending;

        ParseClient.Initialize("wSjuNTbtjVLRaedXvOoaf9S5cTbkuQohTulNZ2vS", "nWZMhXRet9Wotlgikb9aUdKf5GFtRiMvduw7w68z");

    }

我们订阅并启用启动后的分析：

protected async override void OnLaunched(LaunchActivatedEventArgs e)
//Generated codes go here
await ParsePush.SubscribeAsync("testchannel");
await ParseAnalytics.TrackAppOpenedAsync();

那就简单的起作用了。您应该根据需要修改代码。希望这有帮助。
