Question

所以我创建了一个包含在线用户列表的站点母版页 但现在每次我导航到另一个页面或刷新页面，它刷新所有连接的客户端列表.. 它真的很烦人，我怎么能避免呢？

  public override Task OnDisconnected(bool stopCalled)
    {
        if (stopCalled)
        {
            var manager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));
            var currentUser = manager.FindByName(Context.User.Identity.Name);
            string name = currentUser.NickName;

            userNames.Remove(name);


            Clients.All.hubReceived(userNames);
        }
        return base.OnDisconnected(stopCalled);
    }

这是我的脱离行动

以及客户方：

     <script>
         $(function () {
             // Reference the auto-generated proxy for the hub.  
             var hub = $.connection.chatHub;
             // Update player list
             hub.client.hubReceived = function (usernames) {
                 $('#onlineUsersList').text("");
                 console.log(usernames.length)
                 if (usernames.length > 0) {
                     for (var i = 0; i < usernames.length; i++) {
                         if (usernames[i] != "")
                             $("#onlineUsersList").append("<div class='userli'> <img src='Content/Images/profilepic.jpg' style='width: 32px; height: 32px;'/><span>" + usernames[i] + "</span></div>")
                         //  $('#usersList').append(usernames[i]);
                     }
                 }
             };
             hub.client.test = function (x) {
                 alert(x);
             };

             $.connection.hub.start();
         });



</script>
