Question

我在更改页面时遇到保存连接的问题。我有一页显示房间列表，第二页显示聊天视图。当我在连接页面上加入连接时加入方法，之后当我选择加入哪个房间时，它会转到ondisconnected然后是JoinGroups然后是Onconnect方法。请告诉我如何连接两个页面？

这里是chathub的javascript：

$(function () {

    // Declare a proxy to reference the hub. 
    var chatHub = $.connection.ChatHub;

    registerClientMethods(chatHub);

    // Start Hub
    $.connection.hub.start().done(function () {
        roomsEvent(chatHub);

        authorize(chatHub);

        registerEvents(chatHub);

    });

});

function authorize(hub) {
    var name = $('#txtMessage').prop('Placeholder');
    hub.server.connect(name);
    $('#displayname').val(name);
    messageClearFocus();
    $('#txtMessage').prop('placeholder', '');
}

function roomsEvent(hub) {
    $('#rooms ul li').not('.nav-header').click(function () {

        $('#rooms ul li').not('.nav-header').removeClass('active');
        $(this).addClass('active');
        var roomKey = $(this).data('value');
        hub.server.joinGroup(roomKey);
    });
}

和Connect方法：

public void Connect(string userName)
        {
            userName = Context.User.Identity.Name;
            if (ConnectedUsers.Any(x => x.ConnectionId == Context.ConnectionId))
                return;

            //Add a new user to the list
            var user = new ChatUser
            {
                ConnectionId = Context.ConnectionId,
                userLogin = userName
            };

            //Add to maintained user list
            ConnectedUsers.Add(user);

            //Add to default group
            //await 
            Groups.Add(user.ConnectionId, user.CurrentGroup);

            //Give the current group an updated list of users
            UpdateGroupUserList(user.CurrentGroup);

            //Alert others that user joined
            var message = string.Format("{0} has joined.", user.userLogin);
            SendGroupAlert(user, message);

            //Alert user that they have joined
            var personalMessage = string.Format("You have joined {0} as {1}.", user.CurrentGroup, user.userLogin);
            SendPersonalAlert(personalMessage);
        }

如果他们必须切换页面以维持连接，则不可能。你能做的就是把它放在一页下。见here
