failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED

今天他们电脑跑报错，显示websocket连接异常......

昨天写了todo 提示，但是忘了对其做修改了

var prefix = ((window.location.protocol === "https:") ? "wss://" : "ws://") + window.location.host + "/ws/client/";
if ('WebSocket' in window) {
    webSocket = new WebSocket(prefix + ip);
}else if ('MozWebSocket' in window) {
    webSocket = new WebSocket(prefix + ip);
}else {
    webSocket = new SockJS(prefix + ip);
}
