html代码:

hub代码：

[HubName("payHub"), Authorize]    public class payHub : Hub    {        public static Dictionary
     
       userPayHub = new Dictionary
      
       ();        public static void Notify(Guid userId, string redirectUrl)        {            if (userPayHub.ContainsKey(userId))            {                Microsoft.AspNet.SignalR.GlobalHost.ConnectionManager.GetHubContext
       
        ()                   .Clients.Client(Hubs.payHub.userPayHub[userId])                   .waitNotify(true, redirectUrl);            }        }        public override Task OnConnected()        {            var uid = this.Context.User.Identity.GetUserId();            userPayHub[uid] = this.Context.ConnectionId;            return base.OnConnected();        }        public override Task OnDisconnected(bool stopCalled)        {            var uid = this.Context.User.Identity.GetUserId();            userPayHub.Remove(uid);            return base.OnDisconnected(stopCalled);        }        public override Task OnReconnected()        {            var uid = this.Context.User.Identity.GetUserId();            userPayHub.Remove(uid);            return base.OnReconnected();        }    }
       
      
     

通知调用Notify方法即可。

关键点：GlobalHost.ConnectionManager.GetHubContext
