curl采集问题

我想实现通过淘宝号查询淘宝买家信誉的功能，就像131458.com的一样。
我的思路是通过curl采集这个网站的数据。但是却被防了，返回给我的是无用的信息。
代码如下：

    $parm=$data['parm']."&_=".time()."326"; //参数    $ch=  curl_init();     $uri="http://www.131458.com/handler/TaobaoInfo.ashx?";    curl_setopt($ch, CURLOPT_URL, $uri.$parm);     curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);     curl_setopt($ch, CURLOPT_HEADER, 0);     curl_setopt($ch, CURLOPT_REFERER, "http://www.131458.com/");     //curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:125.67.52.246', 'CLIENT-IP:125.67.52.246'));      curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.153 Safari/537.36 SE 2.X MetaSr 1.0"); /     $return = curl_exec($ch);       curl_close($ch);       echo $return;

请问还要添加什么，才能模拟浏览器访问，采集到正常数据。

抓包看看呢？一般都是header里面需要啥，就都传过去

首先，你的方法不对，则是chrome F12下跟踪的结果，CURL命令如下：

curl "http://www.131458.com/handler/TaobaoInfo.ashx?tbNickInfoJson=hades&token=736905fff9ee639a4b5f46b53526434b_0b32d3aec47ad29fef2d7ddb67831933&_=1447405734036" -H "Cookie: ASP.NET_SessionId=4ki3s2yhj2555bzxlbvdqhju; Hm_lvt_ccc93bebd5e7bdc84975186073891702=1447405635; Hm_lpvt_ccc93bebd5e7bdc84975186073891702=1447405635; bdshare_firstime=1447405634805" -H "Accept-Encoding: gzip, deflate, sdch" -H "Accept-Language: zh-CN,zh;q=0.8" -H "User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.86 Safari/537.36" -H "Accept: application/json, text/javascript, */*; q=0.01" -H "Referer: http://www.131458.com/" -H "X-Requested-With: XMLHttpRequest" -H "Connection: keep-alive" --compressed

非常感谢你。
我现在有一个问题，就是获取了d之后，会调用一个$.TO函数，返回的结果你是怎么分析出来，是一个md5(d."vvl81")的，我只看到了定义了C="vvl",然后他手动添加了"8"，最后一个"1"是怎么知道的。
主要是网站现在已经改了，在后面加个"1"再md5已经和网站的数据不一样了。

你可以在console里alert($.To);

return e = 2147483648 & a, f = 2147483648 & b, c = 1073741824
你看下他引用的jquery文件,在最后加了个函数。
看到这几个数字就是MD5加密了,再把格式化下,可以看出加了个1了。

要是被改了估计被发现采集了吧

你看下这网站定义的歌函数,现在变成了
_token=$.To(data.d+c+ "822")+"_"+data.d

所以还是一样的,
