我正在尝试优化服务器上​​的推送通知。现在我一个一个地发送这些（带有一个旧图书馆），这需要一段时间（4小时）。

我重构了我的服务以发送带有大量设备令牌的通知（现在我尝试批量处理 500 个令牌）。为此，我正在使用Redth/PushSharp库。我按照示例代码进行了修改，然后将其调整为将通知发送到多个设备令牌。

PushService service = new PushService();

//Wire up the events
service.Events.OnDeviceSubscriptionExpired += new PushSharp.Common.ChannelEvents.DeviceSubscriptionExpired(Events_OnDeviceSubscriptionExpired);
service.Events.OnDeviceSubscriptionIdChanged += new PushSharp.Common.ChannelEvents.DeviceSubscriptionIdChanged(Events_OnDeviceSubscriptionIdChanged);
service.Events.OnChannelException += new PushSharp.Common.ChannelEvents.ChannelExceptionDelegate(Events_OnChannelException);
service.Events.OnNotificationSendFailure += new PushSharp.Common.ChannelEvents.NotificationSendFailureDelegate(Events_OnNotificationSendFailure);
service.Events.OnNotificationSent += new PushSharp.Common.ChannelEvents.NotificationSentDelegate(Events_OnNotificationSent);
service.Events.OnChannelCreated += new PushSharp.Common.ChannelEvents.ChannelCreatedDelegate(Events_OnChannelCreated);
service.Events.OnChannelDestroyed += new PushSharp.Common.ChannelEvents.ChannelDestroyedDelegate(Events_OnChannelDestroyed);

//Configure and start ApplePushNotificationService
string p12Filename = ...
string p12FilePassword = ...

var appleCert = File.ReadAllBytes(p12Filename);

service.StartApplePushService(new ApplePushChannelSettings(true, appleCert, p12FilePassword));

var appleNotification = NotificationFactory.Apple();

foreach (var itemToProcess in itemsToProcess)
{
    itemToProcess.NotificationDateTime = DateTime.Now;
    mobile.SubmitChanges();

    string deviceToken = GetCleanDeviceToken(itemToProcess.MobileDevice.PushNotificationIdentifier);
    appleNotification.ForDeviceToken(deviceToken);
}

service.QueueNotification(appleNotification
    .WithAlert(itemsToProcess[0].MobileDeviceNotificationText.Text)
    .WithSound("default")
    .WithBadge(0)
    .WithCustomItem("View", itemsToProcess[0].Value.ToString()));

//Stop and wait for the queues to drains
service.StopAllServices(true);

然后我尝试向 2 个设备发送 3 个通知。只有第一个设备得到了它们（问题与设备无关，因为我分别尝试了它们）。紧接着在PushChannelBase 类中引发 OperationCanceledException 。所以我不知道怎么了。任何的想法？

您应该为每个要处理的项目排队单独的通知。
无法在单个通知上设置多个设备令牌。OperationCanceledException 将发生，因为您这样做了。

示例：控制台 C# 应用程序

这假设

  1. 您有有效的生产和开发证书
  2. 您在数据库中存储了多个设备令牌
  3. 你有一个来自你的数据库的通知

  4. 您正在使用PushSharp库
