jQuery-PHP跨域请求数据

jQuery:

//获取域名
function getDomain(url){
    var a = document.createElement('a');
    a.href = url;
    url=a.hostname;
    return url;
}

//记录访客
function recordVisitor(){
    var referrerMz = escape(getDomain(document.referrer));
    var hrefMz = escape(getDomain(window.location.href));
    sendInfo="judgeMz=413322&referrerMz="+escape(referrerMz)+"&hrefMz="+escape(hrefMz);
    $.ajax({ 
        type: "get", 
        async: true, 
        url: "http://www.mazey.net/config/api/record-receive.php", 
        data:{judgeMz:413322,referrerMz:referrerMz,hrefMz:hrefMz}, 
        dataType: "jsonp", 
        jsonp: "callback",
        jsonpCallback:"returnFun",
        success: function(data){ 
            myArr=data.split("-|-")
            if("0507"==myArr[0]){
                console.log(myArr[1]);
            }else if("0215"==myArr[0]){
                console.log(myArr[1]);
            }
        }, 
        error: function(){ 
            console.log("Server Error!");
        } 
    });
}

//加载
$(document).ready(function () { 
    recordVisitor();
}); 

PHP:

<?php
require '../config.php';
$judgeMz=$_GET["judgeMz"];//TODO 后续做一个验证不是413322的报错
$referrerMz=$_GET["referrerMz"];
$hrefMz=$_GET["hrefMz"];
$visitorIP=getIP();

$data = returnFun($referrerMz,$hrefMz,$visitorIP); 
exit($_GET['callback'] . '(' . json_encode($data) . ')'); 

function returnFun($referrerMz,$hrefMz,$visitorIP) { 
    $urlRecordVisitor='http://www.mazey.cn/config/config-asp/api/record-receive.asp?referrerMz='.$referrerMz.'&hrefMz='.$hrefMz.'&visitorIP='.$visitorIP;
    $resultMz = file_get_contents($urlRecordVisitor);
    return $resultMz;
}
?>

其他：

因为http://www.mazey.cn/config/config-asp/api/record-receive.asp在国内，所以访问起来好像有点慢。准备按照asp重写下php的后端写入代码，本来计划了不少事情，其他事情这一步做完以后再说吧。
