本文实例讲述了PHP获取youku视频真实flv文件地址的方法。分享给大家供大家参考。具体分析如下：
有一站长要我帮助它做一个可以自动测试出youku视频网站的flv真实地址,下面我整理了一下午解决了此问题非常的不错,大家可参考一下.
这个是借力打力,只是抓去朋友网的内容,不过相当好用,代码如下:
<?php <br />$videourl='http://v.youku.com/v_show/id_XMjA5MjQ0OTQ0.html'; <br />function get_content($url ,$data){ <br /> if(is_array($data)){ <br /> $data = http_build_query($data, '', '&'); <br /> } <br /> $ch = curl_init(); <br /> curl_setopt($ch, CURLOPT_RETURNTRANSFER, true ); <br /> curl_setopt($ch, CURLOPT_POST, 1); <br /> curl_setopt($ch, CURLOPT_HEADER, 0); <br /> curl_setopt($ch, CURLOPT_URL,$url); <br /> curl_setopt($ch, CURLOPT_POSTFIELDS, $data); <br /> $result = curl_exec($ch); <br /> return $result; <br />} <br />$str = get_content('http://share.pengyou.com/json.php?mod=usershare&act=geturlinfo',array('url'=>$videourl)); <br />$str=json_decode($str); <br />var_dump($str); <br />?>
这个测试出来的只是swf文件并不是我们要的flv文件了,后来参考一站长的写法进行了改进,核心代码如下:
<?php <br />function fetch_youku_flv($url){ <br /> preg_match("#id_(.*?).html#",$url,$out); <br /> $id=$out[1]; <br /> $content=get_curl_contents('http://v.youku.com/player/getPlayList/VideoIDS/'.$id); <br /> $data=json_decode($content); <br /> foreach($data->data[0]->streamfileids AS $k=>$v){ <br /> $sid=getSid(); <br /> $fileid=getfileid($v,$data->data[0]->seed); <br /> $one=($data->data[0]->segs->$k); <br /> if($k == 'flv' || $k == 'mp4') return "http://f.youku.com/player/getFlvPath/sid/{$sid}_00/st/{$k}/fileid/{$fileid}?K={$one[0]->k}"; <br /> continue; <br /> } <br />} <br />function get_curl_contents($url, $second = 5){ <br /> if(!function_exists('curl_init')) die('php.ini未开启php_curl.dll'); <br /> $c = curl_init(); <br /> curl_setopt($c,CURLOPT_URL,$url); <br /> $UserAgent=$_SERVER['HTTP_USER_AGENT']; <br /> curl_setopt($c,CURLOPT_USERAGENT,$UserAgent); <br /> curl_setopt($c,CURLOPT_HEADER,0); <br /> curl_setopt($c,CURLOPT_TIMEOUT,$second); <br /> curl_setopt($c,CURLOPT_RETURNTRANSFER, true); <br /> $cnt = curl_exec($c); <br /> $cnt=mb_check_encoding($cnt,'utf-8')?iconv('gbk','utf-8//IGNORE',$cnt):$cnt; //字符编码转换 <br /> curl_close($c); <br /> return $cnt; <br />} <br />function getSid() { <br /> $sid = time().(rand(0,9000)+10000); <br /> return $sid; <br />} <br />function getkey($key1,$key2){ <br /> $a = hexdec($key1); <br /> $b = $a ^ 0xA55AA5A5; <br /> $b = dechex($b); <br /> return $key2.$b; <br />} <br />function getfileid($fileId,$seed) { <p>4本文￥来源gao!%daima.com搞$代*!码$网9</p><pre>搞代gaodaima码
$mixed = getMixString($seed);
$ids = explode(“*”,$fileId);
unset($ids[count($ids)-1]);
$realId = “”;
for ($i=0;$i < count($ids);++$i) {
$idx = $ids[$i];
$realId .= substr($mixed,$idx,1);
}
return $realId;
}
function getMixString($seed) {
$mixed = “”;
$source = “abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ/:._-1234567890”;
$len = strlen($source);
for($i=0;$i< $len;++$i){
$seed = ($seed * 211 + 30031) % 65536;
$index = ($seed / 65536 * strlen($source));
$c = substr($source,$index,1);
$mixed .= $c;
$source = str_replace($c, “”,$source);
}
return $mixed;
}
?>
调用方法,代码如下:
$url='http://v.youku.com/v_show/id_XMzg2OTQ3MjQw.html';<br />echo fetch_youku_flv($url);
访问:
http://xiaomizhou.net/demo/flv.php?url=http://v.youku.com/v_show/id_XMzg2OTQ3MjQw.html
输出的结果是:
http://f.youku.com/player/getFlvPath/sid/138035737110468_00/st/flv/fileid/03000201004F97EF4A2E350467A09DB266E872-5522-225F-DC45-40B4E1F9BE49?K=c2a4327df2bb5a65261d40ea
这个是可以直接下载的.
希望本文所述对大家的php程序设计有所帮助。
