然后我用PHP实现了这个功能,我觉得用PHP来做这项工作简直是一种享受!使用其提供的强大的HTML页面处理函数和正则表达式,短短的几行代码就能搞定这个功能。
贴一下关键代码:
复制代码 代码如下:
//获取优酷页面中的flash地址
function get_flash_url( $url )
{
$lines = file($url);
foreach ($lines as $linenum=> $line) {
preg_match_all('||',$line,$result);
$swfurl=$result[1][0];
if(!empty($swfurl))
return $swfurl;
}
}
?>
$url=$_SERVER["QUERY_STRING"];
$flashurl= get_flash_url($url);
echo ( $flashurl );
?>
比如这个文件我们存为 test.php,那么我们只需要运行 test.php?优酷视频的url 就可以解析出FLASH地址了。
思路很简单,就是先看看优酷视频网页的HTML代码里关键FLASH地址那段的特征。随便找个网页,比如我们可以看到这一段:
然后使用正则表达式来将其中的地址段匹配掉,就OK了。
