【转】百度搜索结果url加密算法 python源码

百度搜索结果都是加密过的，比如：

baidu.com/link?url=a3f48d30fc293c5e471ef23de092fddc99e8cd902143baf828cbc787e08f0e3f3c49a8f7

以下就是用python实现加密的方法，此方法的缺点是无法加密https的链接，算是比较老的算法，但是仍然可以用(常被seo人士用于shua排名等领域)。

访问网址即可正常跳转。

另外，如何获取加密之后的真实地址就简单多了，直接http访问加密后的地址，获取返回头部里的301跳转地址就行了。

<?php
$url = "http://www.baidu.com/link?url=nS2MGJqjJ4zBBpC8yDF8xDh8vibi1lVeE7gGr9UONBu";

$info = parse_url($url);
$fp = fsockopen($info['host'], 80,$errno, $errstr, 30);
fputs($fp,"GET {$info['path']}?{$info['query']} HTTP/1.1\r\n");
fputs($fp, "Host: {$info['host']}\r\n");
fputs($fp, "Connection: close\r\n\r\n");
$rewrite = '';
while(!feof($fp)) {
    $line = fgets($fp);
    if($line != "\r\n" ) {
        if(strpos($line,'Location:') !== false) {
            $rewrite = str_replace(array("\r","\n","Location: "),'',$line);
        }
    }else {
        break;
    }
}
var_dump($rewrite); //结果显示：string(22) "http://www.google.com/" 
?>
