  • 1.Modify hub class

    obj.client.log = function (data) {
                      $("#logList").append("<li>----------------New connection------------</li>");
                      $("#logList").append("<li>connection id:" + data.conId + "</li>");
                      $("#logList").append("<li>connection status:" + data.conId + "</li>");
                      $("#logList").append("<li>connection transport:" + data.transport + "</li>");
                      $("#logList").append("<li>connection host:" + data.host + "</li>");
                      $("#logList").append("<li>connection port:" + data.port + "</li>");
                      $("#logList").append("<li>connection user name:" + data.uname + "</li>");
                  }

• 2.Modified client side

  class Info
  {
        public string conId { get; set; }
        public string  conStatus { get; set; }
        public string transport { get; set; }
        public string host { get; set; }
        public string port { get; set; }
        public string uname { get; set; }
  }
  
  [HubName("myhub")]
  public class MyHub: Hub
  {
    public override Task OnConnected()
    {
        Info i = new Info();
        i.conId = Context.ConnectionId.ToString();
        i.conStatus = Context.Headers["Connection"].ToString();
        i.transport = Context.QueryString["transport"];
        i.host = Context.Request.Url.Host;
        i.port = Context.Request.Url.Port.ToString();
        i.uname = Context.User.Identity.Name;
  
        return Clients.All.log(i);
    }
