试过用 curl 和 socket 都取不到真实的最终url

作者是否是用这种方式增加“假”的目标网址的流量？

如何才能用代码获得真实的调整url？

url

socket

curl

卧槽！我在公司啊，给我跳转到草榴去了！
...

file_get_contents('http://i.doovoo.biz/1.php');
var_dump($http_response_header);exit;

请求完成之后直接拿头信息就可以得到最终跳转的url了
注意前面几个 302 跳转

array (size=26)
0 => string 'HTTP/1.1 302 Found' (length=18)
1 => string 'Date: Thu, 23 Jul 2015 08:33:26 GMT' (length=35)

拿到了，他的服务器稍微检查了下header看是不是爬虫，所以你爬的时候需要带一个header：

$opt = array(
'http' => array(
'method' => 'GET',
'header' => "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8\r\n" .
"User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.89 Safari/537.36\r\n"
),
);
stream_context_get_default($opt);
print_r(get_headers('http://i.doovoo.biz/1.php'));exit;

然后拿最后一个Location就行了

[25] => Location: https://www.lettoelectronics.com/site/www.bd.com/
[26] => HTTP/1.1 200 OK
[27] => Date: Thu, 23 Jul 2015 09:05:23 GMT
[28] => Server: Apache/2.2.27 (CentOS)
