SignalR客戶端方法沒有被解雇

Question

我正在嘗試在Asp.Net MVC中使用SignalR 2.4.1，我已經完成了下面的示例代碼，

我正在使用WithGenerateProxy建立連接。

Hub方法在服務器端調用，在客戶端接收日志

[格林威治標准時間18:56:10 + 0530（印度標准時間）] SignalR：在集線器“ChatHub”上觸發客戶端集線器事件“SendAsync”。

但客戶端方法廣播沒有被觸發。

在我的代碼下面，我缺少什么。

C＃

public class ChatHub : Hub
    {
        public void Broadcast()
        {
            Clients.All.SendAsync("Broadcast");
        }
    }

Startup.cs

using System;
using System.Threading.Tasks;
using Microsoft.Owin;
using Owin;

[assembly: OwinStartup(typeof(SampleSignalR.Startup))]

namespace SampleSignalR
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            app.MapSignalR();
            // For more information on how to configure your application, visit http://go.microsoft.com/fwlink/?LinkID=316888
        }
    }
}

JavaScript的

<script type="text/javascript" src="~/scripts/jquery-1.6.4.min.js"></script>
<script type="text/javascript" src="~/scripts/jquery.signalR-2.4.1.js"></script>
<script type="text/javascript" src="~/SignalR/hubs"></script>

<script>
var connection = $.connection.chatHub;

    $.connection.hub.url = "http://localhost:64573/signalr";
    $.connection.hub.logging = true;
    $.connection.hub.connectionSlow(function () {
        console.log("slow connection");
    });
    connection.on("Broadcast", function () {
        console.log("Successs");
    });
    $.connection.hub.start().done(function () {
        connection.server.broadcast().done(function () {
            console.log("calling server function");
        });
    });
</script>

Answer 1

我認為如果你真的想發送一些數據它會工作：

var data = "hello world";
Clients.All.SendAsync("Broadcast", data);

對於接收數據的函數，請輸入參數：

connection.on("Broadcast", function (data) {
    console.log(data);
});

Answer 2

你需要在js中添加客戶端方法

       chat.client.receiveBroadcast = function (data) {
           console.log(data);
        };

在Hub

    public void Broadcast()
    {
        Clients.All.receiveBroadcast("Broadcast");
    }
