cocos creator http工具类

直接上代码  复制项目直接可用 

我将官方文档中的http 用js 单利的模式 改了下 

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'] + "'"));                }            }        });
