ReceiveMessage 不适用于 abp.signalR

Question

我正在使用 abp.signalR 但我遇到了与 ReceiveMessage 事件相关的问题，我想知道收到消息后我尝试了以下代码但没有任何反应：\

this.chatHub.on("ReceiveMessage", (username: string, message: string) => { 


});

我的后端代码： 我需要向后端添加更多代码吗？


namespace HealthMapControlPanel.ChatAppService
{
   public class MyChatHub : Hub, ITransientDependency
    {
         public IAbpSession AbpSession { get; set; }

    public ILogger Logger { get; set; }

    public MyChatHub()
    {
        AbpSession = NullAbpSession.Instance;
        Logger = NullLogger.Instance;
    }

    public async Task SendMessage(string message)
    {
        await Clients.All.SendAsync("getMessage", string.Format("User {0}: {1}", AbpSession.UserId, "the message that has been sent from client is"+message));
    }
        public async Task SendToUser(string msg, long userId)
        {
            if (this.Clients != null)
            {
                await Clients.User(userId.ToString()).SendAsync("Send", msg, "From Server by userID ", Context.ConnectionId, Clock.Now);
            }
            else
            {
                throw new UserFriendlyException("something wrong");
            }
        }


        public override async Task OnConnectedAsync()
    {
        await base.OnConnectedAsync();
        Logger.Debug("A client connected to MyChatHub: " + Context.ConnectionId);
    }

    public override async Task OnDisconnectedAsync(Exception exception)
    {
        await base.OnDisconnectedAsync(exception);
        Logger.Debug("A client disconnected from MyChatHub: " + Context.ConnectionId);
    }


    }


}

Answer 1

这不起作用，因为您在客户端和服务器上订阅了 "ReceiveMessage"，而您正在执行 .SendAsync("Send");

您应该在客户端上更改为：

this.chatHub.on("Send", (username: string, message: string) => { 
});

或在服务器上：

await Clients.User(userId.ToString()).SendAsync("ReceiveMessage", msg, "From Server by userID ", Context.ConnectionId, Clock.Now);

更新:

this.chatHub.on("getMessage", (username: string, message: string) => { 
});
