ASP.NET SignalR 踩坑记录（ASP.NET）

1. 在代码中调用Hub

找到一种方法存储下connectionId，在代码中就可以通过其他凭据调用前台。

    public class HubHandler
    {
        private readonly static Lazy<HubHandler> _instance = new Lazy<HubHandler>(
        () => new HubHandler(GlobalHost.ConnectionManager.GetHubContext<MyHub>()));
        private IHubContext _context;

        public static HubHandler Default => _instance.Value;

        private HubHandler(IHubContext context)
        {
            _context = context;
        }

        public void Enter(string connectionId)
        {
            _context.Clients.Client(connectionId).enter();
 
        }
    }

2.jquery版本、执行server端代码

    <script src="~/Scripts/jquery-2.2.4.min.js"></script> <!--使用jquery3.x会有问题-->
    <script src="~/Scripts/jquery.signalR-2.2.2.min.js"></script>
    <script src="/signalr/hubs"></script>
    <script>
        $(function () {
            var hub = $.connection.myHub;
            hub.client.enter = function () {
                console.log("enter");
            };
            $.connection.hub.start().done(function () { //调用server的代码请等待启动完成
                hub.server.connectTest("myid");
            });
        });
    </script>
