cocos creator http工具类(xmlRequest)

});

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'] + "'"));

            }        }    });
