我正在使用push sharp实现推送通知,我有2种类型的消息,我正在发送推荐喜欢和NewFollower,我可以发送推荐喜欢的消息尽可能多,一切都很好,但发送单个NewFollower消息只会导致服务停止响应,没有例外,或任何事件调用。这在生产环境和开发环境中都会发生
服务创建逻辑如下:
private void InitApplePushService()
{
try
{
string appDataPath = HttpContext.Current.Server.MapPath("~/app_data");
//***** Development Server *****//
string file = Path.Combine(appDataPath, "PushSharp.PushCert.Development.p12");
var appleCert = File.ReadAllBytes(file);
_applePushService = new ApplePushService(new ApplePushChannelSettings(false, appleCert, "XXX"));
_applePushService.OnChannelCreated += OnChannelCreated;
_applePushService.OnChannelDestroyed += OnChannelDestroyed;
_applePushService.OnChannelException += OnChannelException;
_applePushService.OnDeviceSubscriptionChanged += OnDeciveSubscriptionChanged;
_applePushService.OnDeviceSubscriptionExpired += OnDeviceSubscriptionExpired;
_applePushService.OnNotificationFailed += OnNorificationFailed;
_applePushService.OnNotificationRequeue += OnNotificationQueued;
_applePushService.OnNotificationSent += OnNOtificationSend;
_applePushService.OnServiceException += OnServiceException;
Trace.TraceInformation("ApplePushService initialized succesfully");
}
catch (Exception e)
{
Trace.TraceError("Error initializing ApplePushService : " + e);
throw;
}
}
推荐消息创建:
private void SendRecomendationLikedMessageToAppleDevice(User likingUser, Recomendation recomendation)
{
var notification = new AppleNotification();
notification.DeviceToken = recomendation.User.PushNotificationID;
notification.Payload.Alert.LocalizedKey = "NewLikeNotification";
notification.Payload.Alert.LocalizedArgs = new List<object> { likingUser.NickName };
notification.Payload.Sound = "default";
notification.Payload.AddCustom("LikingUser", likingUser.NickName);
notification.Payload.AddCustom("AlertType", "RecomendationLiked");
notification.Payload.AddCustom("ID", likingUser.ID);
notification.Payload.AddCustom("ImageUrl", likingUser.ImageUrl);
_applePushService.QueueNotification(notification);
}
NewFollower消息创建:
private void SendNewFollowingUserMessageToAppleDevice(User followingUser, User followedUser)
{
var notification = new AppleNotification();
notification.DeviceToken = followedUser.PushNotificationID;
notification.Payload.Alert.LocalizedKey = "NewFollowingUserNotification";
notification.Payload.Alert.LocalizedArgs = new List<object> { followingUser.NickName };
notification.Payload.Sound = "default";
notification.Payload.AddCustom("followingUser", followingUser.NickName);
notification.Payload.AddCustom("AlertType", "NewFollowingUser");
notification.Payload.AddCustom("ID", followingUser.ID);
notification.Payload.AddCustom("ImageUrl", followingUser.ImageUrl);
Trace.TraceInformation("Trying to send notifications: "+ notification);
_applePushService.QueueNotification(notification);
//_pushService.QueueNotification(notification);
}
第一个工作,第二个静默终止推送服务…
任何想法?
终于解决了…
问题在于生成的json字符串的长度。似乎最大值是255个字符。再高一点,它就会无声地失败…
小心。
