angular - 实时通知未发送

Question

我尝试在 ASP.NET Boilerplate 中显示实时通知，但未发送。

public override async Task<MessagesDto> Create(MessagesCreateDto input)
{
    var MessagesCore = ObjectMapper.Map<MessagesCore>(input);            
    MessagesCore.UserId = Convert.ToInt32(AbpSession.UserId);
    MessagesCore.CreationId = Convert.ToInt32(AbpSession.UserId);
    MessagesCore.FromUserId = Convert.ToInt32(AbpSession.UserId);
    MessagesCore.CreationTime = DateTime.Now;
    MessagesCore.LastModificationId = Convert.ToInt32(AbpSession.UserId);
    MessagesCore.LastModificationTime = DateTime.Now;

    _stateRepository.Insert(MessagesCore);
    CurrentUnitOfWork.SaveChanges();

    UserIdentifier identifier = new UserIdentifier(1,input.ToUserId);
    await _notificationSubscriptionManager.SubscribeAsync(new UserIdentifier(1, input.ToUserId), "NewMessage");
    await _notificationPublisher.PublishAsync("NewMessage", new SentMessageNotificationData("Test", "New Message"), userIds: new[] { identifier });

    return MapToEntityDto(MessagesCore);
}

SentMessage通知数据类:

[Serializable]
public class SentMessageNotificationData : NotificationData
{
    public string SenderUserName { get; set; }

    public string FriendshipMessage { get; set; }

    public SentMessageNotificationData(string senderUserName, string friendshipMessage)
    {
        SenderUserName = senderUserName;
        FriendshipMessage = friendshipMessage;
    }
}

数据存储在通知表中，但客户端不显示通知消息。

app.component.ts中的SignalR代码:

ngOnInit(): void {
  if (this.appSession.application.features['SignalR']) {
    SignalRHelper.initSignalR();
  }

  abp.event.on('abp.notifications.received', userNotification => {
    abp.notifications.showUiNotifyForUserNotification(userNotification);
    if (userNotification.notification.data.type === 'Abp.Notifications.LocalizableMessageNotificationData') {
        var localizedText = abp.localization.localize(
            userNotification.notification.data.message.name,
            userNotification.notification.data.message.sourceName
        );

        $.each(userNotification.notification.data.properties, function (key, value) {
            localizedText = localizedText.replace('{' + key + '}', value);
        });

        alert('New localized notification: ' + localizedText);
    } else if (userNotification.notification.data.type === 'Abp.Notifications.MessageNotificationData') {
        alert('New simple notification: ' + userNotification.notification.data.message);
    }
    //Desktop notification
    Push.create("AbpZeroTemplate", {
      body: userNotification.notification.data.message,
      icon: abp.appPath + 'assets/app-logo-small.png',
      timeout: 6000,
      onClick: function () {
        window.focus();
        this.close();
      }
    });
  });
}

i am on netcoreapp2.0

• SignalR 仍处于 .NET Core 的 1.0.0-alpha2-final 版本。
• 2.x 仅在 2018 年第一季度/第二季度稳定。

更新 1

Abp.AspNetCore.SignalR NuGet 包已发布。

阅读 SignalR AspNetCore Integration 的文档.

您可以try并进行必要的changes到您的文件。 或者只是等待它被释放。

更新2

您现在可以download具有 AspNetCore.SignalR 预览的模板的 v3.4.1。
