    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?

    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)
    2 => string 'Server: Apache' (length=14)
    3 => string 'X-Powered-By: PHP/5.5.9-1ubuntu4.4' (length=34)

    12 => string 'X-Powered-By: PHP/5.2.17' (length=24)

    15 => string 'Location: https://www.caodsma.com/t/' (length=36)
    16 => string 'Content-Length: 0' (length=17)
    17 => string 'Connection: close' (length=17)

    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)
