他是如何跳转的~~
如何通过PHP得到此URL跳转后的URL

回复讨论(解决方案)

如果不是在代码内跳转，估计要用socket才能抓到header

curl好像也有获取header的，你查查

估计是根据后面的变量实现跳转的

fsockopen方式获取这个页面，分析里面的Location后获得跳转地址。

$headers = get_headers('http://www.chong4.com.cn/cydb/go.php?7218_29882_22t', true);if(is_array($headers['Location'])){    $headers['Location'] = array_pop($headers['Location']);}$script = file_get_contents($headers['Location']);echo $script;

它最后的跳转像是JS来做的，简单的做法是你找出它的规律，提取出它的网址内容

通过 302 跳转到 'http://s.click.taobao.com/t_js?tu=http%3A%2F%2Fs.click.taobao.com%2Ft%3Fe%3DzGU34CA7K%252BPkqB07S4%252FK0CFcRfH0G7DbPkiN9MMH7EkQ%252B3KnWlM5fPrbcF5EKeNJ3Ts8ijJ4%252F77oX8O2iw1qEuhEhgaut73j9hJ3YPtNYm616DyrkK0aE1E31WN8TefmpCriY9EJ5O4JCWiRap3Rj1hfNxI2HSqhk8lK01rAylx5%252F9fHp6i%252FPRGYAGeegVo%252F%26spm%3D2014.12231445.1.0%26u%3D22t7218%26ref%3D%26et%3DjFBB1tzvZVjt5A%253D%253D
可以得到一段 js 代码
其中有 qs = location.search.split("?")[location.search.split("?").length-1].split("&");
所以需要用上述url 替换掉 location.search
执行js代码后，得到







frameBorder=0> frameBorder=0>

你可以继续跟踪那些js文件中的代码

需要的就是这段，如何取得到？

$url = 'http://www.chong4.com.cn/cydb/go.php?7218_29882_22t';$ch = curl_init();curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_HEADER, true);curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);$content = curl_exec($ch);echo $content;

得到
