Question

我正在尝试优化服务器上的推送通知。现在我逐个发送（带有一个旧库）并且需要一段时间（4小时）。

我重构了我的服务，发送了一个包含大量设备令牌的通知（现在我尝试使用500个令牌批量）。为此，我正在使用Redth/PushSharp库。我跟着sample code然后我调整它以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台设备发送3个通知。只有第一台设备才能获得它们（问题与设备无关，因为我分别尝试了这两种设备）。在此之后，PushChannelBase class中抛出了OperationCanceledException。所以我不知道出了什么问题。有什么想法吗？

Answer 1

您应为每个要处理的项目排队单独的通知在单个通知上无法设置多个设备令牌。将发生OperationCanceledException，因为你这样做。

Answer 2

示例：控制台C＃应用程序

这假定

您拥有有效的生产和开发证书
您已在数据库中存储了多个设备令牌
您的通知来自您的数据库

您正在使用PushSharp资料库
