在项目根目录建Hubs文件

using Microsoft.AspNet.SignalR;
using Microsoft.AspNet.SignalR.Hubs;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace SignalRTest.Hubs
{
    [HubName("pushHub")]//指定名称
    public class PushHub : Hub
    {
        public void send(string message)
        {
            message += DateTime.Now.ToString();
            Clients.All.sendMessage(message);//定义客户端函数
        }
    }
}
