前几天买了本cocos2d-x实战js卷，学习到15章的基于Node.js的Socket.IO网络通信，于是按教材说的方法成功搭建了node.js，安装了Socket.IO模块包（0.9.16版）。接着我到智捷课堂下了对应的服务端可客户端的源码，服务端用dos命令行成功运行，客户端用COCOS IDE生成了工程文件并运行。

虽然似乎有些文件没有找到，但客户端与服务器端已经成功连接了。
但当我点击发送信息的时候，就报错了
JS: onMenuCallback
JSB SocketIO.send method called
jsb: ERROR: File …\manual\network\jsb_socketio.cpp: Line: 226, Function: js_cocos2dx_SocketIO_send
Invalid Native Object
JS: src/app.js:46:Error: Invalid Native Object
jsb_socketio.cpp应该是cocos自带的，而app.js是我下的服务器端代码
源码如下：
var _sioClient;
var SocketIO = SocketIO || io;
var HelloWorldLayer = cc.Layer.extend({
ctor:function () {
//////////////////////////////
// 1. super init first
this._super();
/////////////////////////////
// 2. add a menu item with "X" image, which is clicked to quit the program
// you may modify it.
// ask director the window size
var size = cc.director.getWinSize();
var lblSendMsg = new cc.LabelBMFont("Send Message", res.fnt_fnt);
var menuItemSendMsg = new cc.MenuItemLabel(lblSendMsg, this.onMenuCallback, this);
var mn = new cc.Menu(menuItemSendMsg);
mn.alignItemsVertically();
this.addChild(mn);
_sioClient = SocketIO.connect("http://localhost:3000/");
_sioClient.tag = "Cocos2d-JS Client1";
//注册服务器端事件
_sioClient.on("callClientEvent", this.callClientEvent);//触发服务器端的callClientEvent事件，同时客户端执行this.callClientEvent方法
_sioClient.on("connect", function() {
cc.log("connect called.");
});
_sioClient.on("message", function(data) {
cc.log(_sioClient.tag + " message received: " + data);
});
_sioClient.on("error", function() {
cc.log("error called..");
});
return true;
},
onMenuCallback:function (sender) {
cc.log("onMenuCallback");
//向服务器发出消息
_sioClient.send("Hello Socket.IO!");//本行报错
//触发服务器callServerEvent事件
_sioClient.emit("callServerEvent","{\"message\":\"Hello Server.\"}");
},
//服务器端回调客户端事件
callClientEvent: function(data) {
var msg = "Server CallBack: "+ _sioClient.tag + " Data :" + data;
cc.log(msg);
}
});
var HelloWorldScene = cc.Scene.extend({
onEnter:function () {
this._super();
var layer = new HelloWorldLayer();
this.addChild(layer);
}
});
我看了一下服务器，一点变化都没有，说明信息并没有发过来。连接应该是正确的，那么就是上面的send出错了，但是错在哪里？app.js中的出错的那一行应该没有语法问题，而jsb_socketio.cpp又是cocos自带的，应该不会有错才对
求大虾解答
