本文介绍如何使用Cocos2d-x游戏引擎通过httpUtils单例模式进行HTTP GET和POST请求，并提供了具体的实现代码及调用示例。

var httpUtils = cc.Class({
extends: cc.Component,

properties: {
    // foo: {
    //    default: null,      // The default value will be used only when the component attaching
    //                           to a node for the first time
    //    url: cc.Texture2D,  // optional, default is typeof default
    //    serializable: true, // optional, default is true
    //    visible: true,      // optional, default is true
    //    displayName: 'Foo', // optional
    //    readonly: false,    // optional, default is false
    // },
    // ...
},

statics: {
    instance: null
},

// use this for initialization
onLoad: function () {
},

httpGets: function (url, callback) {
    var xhr = cc.loader.getXMLHttpRequest();
    xhr.onreadystatechange = function () {
        if (xhr.readyState === 4 && (xhr.status >= 200 && xhr.status < 300)) {
            var respone = xhr.responseText;
            callback(respone);
        }
    };
    xhr.open("GET", url, true);
    if (cc.sys.isNative) {
        xhr.setRequestHeader("Accept-Encoding", "gzip,deflate");
    }

    // note: In Internet Explorer, the timeout property may be set only after calling the open()
    // method and before calling the send() method.
    xhr.timeout = 5000;// 5 seconds for timeout

    xhr.send();
},

httpPost: function (url, params, callback) {
    var xhr = cc.loader.getXMLHttpRequest();
    xhr.onreadystatechange = function () {
        cc.log('xhr.readyState='+xhr.readyState+'  xhr.status='+xhr.status);
        if (xhr.readyState === 4 && (xhr.status >= 200 && xhr.status < 300)) {
            var respone = xhr.responseText;
            callback(respone);
        }else{
              callback(-1);
        }
    };
    xhr.open("POST", url, true);
    if (cc.sys.isNative) {
        xhr.setRequestHeader("Accept-Encoding", "gzip,deflate");
    }

    // note: In Internet Explorer, the timeout property may be set only after calling the open()
    // method and before calling the send() method.
    xhr.timeout = 5000;// 5 seconds for timeout

    xhr.send(params);
}

});

httpUtils.getInstance = function () {
if (httpUtils.instance == null) {
httpUtils.instance = new httpUtils();
}
return httpUtils.instance;
};

js 单利的使用方法：

httpUtils.getInstance().httpPost('http://192.168.1.107:8081/index.php?s=/app/verify/sendverify.html', params, function (data) {
if (data === -1) {
cc.log('请检查网络！');
} else {
var jsonD = JSON.parse(data);
if (jsonD['status'] === 1) {
cc.log('发送成功');
} else {
cc.log('发送失败' + ':' + eval("'" + jsonD['message'] + "'"));
