jquery stomp websockets服务器重新连接重新初始化

我有一个websocket应用程序,通过stomp连接到我的Java后端。js文件。

function connect() {

            var socket = new SockJS('<?php echo $rootbasename;?>wsconnect');
            stompClient = Stomp.over(socket);
            stompClient.debug = null;
            stompClient.connect({}, function (frame) {
                console.log('Connected: ' + frame);
                console.log('/queue/messages/' + widgetId + "/" + $.cookie(cookiename));
                stompClient.subscribe('/queue/messages/' + widgetId + "/" + $.cookie(cookiename), function (result) {
                    //code here

                }, {userToken: $.cookie(cookiename), widgetId: widgetId});

                stompClient.subscribe('/queue/makereadresult/' + widgetId + '/' + $.cookie(cookiename), function (result) {

});
