Question

我有一个自托管信号器集线器，配置如下：

using System;
using Microsoft.AspNet.SignalR;
using Microsoft.Owin.Hosting;
using Owin;
using Microsoft.Owin.Cors;

namespace SignalRSelfHost
{
    class Program
    {
        static void Main(string[] args)
        {
            // This will *ONLY* bind to localhost, if you want to bind to all addresses
            // use http://*:8080 to bind to all addresses. 
            // See http://msdn.microsoft.com/en-us/library/system.net.httplistener.aspx 
            // for more information.
            string url = "http://localhost:8080";
            using (WebApp.Start(url))
            {
                Console.WriteLine("Server running on {0}", url);
                Console.ReadLine();
            }
        }
    }
    class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            app.UseCors(CorsOptions.AllowAll);
            app.MapSignalR();
        }
    }
    public class MyHub : Hub
    {
        ConcurrentDictionary<string, string[]> userList = new ConcurrentDictionary<string, string[]>();

        public void Send(string name, string message)
        {
            Clients.All.addMessage(name, message);
        }
    }
}

我有一些将要运行的过程＆＃34;永远＆＃34;

CancellationTokenSource cts = new CancellationTokenSource();
var token = cts.Token;

Task.Factory.StartNew(() =>
{
    while (true)
    {
        //update the userList wich should be shared with hub, and call some signalr notification on hub clients
        Thread.Sleep(1000);
    }
}, token, TaskCreationOptions.LongRunning, TaskScheduler.Default);

我试图将此进程放在集线器构造函数中，但它没有运行。

那么，如何实现这个目标？

Answer 1

Hub仅在SignalR请求期间存在，因此您不应在Hub中将此类代码移至后台工作程序并使用

调用集线器

GlobalHost.ConnectionManager.GetHubContext<MyHub>().Clients.All.addMessage(name, message);

如何在一些并行（后台）进程中使用signalr？
