关于socketio链接服务器的的emit发送不成功

Question

就想这样的

 var json;
        xxim = {}
        xxim.socket = false;
        function userSubmit(data) {
            json = data;
            json.indexOf("company_id");
            var company_id_data = json.substr(json.indexOf("company_id") + 13, 1);
            var url = 'http://192.168.1.113:2585';
            if (xxim.socket == false) {
                xxim.socket = io.connect(url, { "transports": ['polling'], "reconnection": true });
            } else {
                return;
            }
            xxim.socket.on('connect', function () {
                xxim.socket.emit("auth", json);//_data
            });
            xxim.socket.on('auth', function (r) {
                alert("hello World");
                console.log('login ok :+++++++++++' + r.sender_id + new Date());
            });
        }
