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 $videourl='http://v.youku.com/v_show/id_XMjA5MjQ0OTQ0.html'; function get_content($url ,$data){ if(is_array($data)){ $data = http_build_query($data, '', '&'); } $ch = curl_init(); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true ); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_URL,$url); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); $result = curl_exec($ch); return $result; } $str = get_content('http://share.pengyou.com/json.php?mod=usershare&act=geturlinfo',array('url'=>$videourl)); $str=json_decode($str); var_dump($str); ?>
这个测试出来的只是swf文件并不是我们要的flv文件了,后来参考一站长的写法进行了改进,核心代码如下:
<?php function fetch_youku_flv($url){ preg_match("#id_(.*?).html#",$url,$out); $id=$out[1]; $content=get_curl_contents('http://v.youku.com/player/getPlayList/VideoIDS/'.$id); $data=json_decode($content); foreach($data->data[0]->streamfileids AS $k=>$v){ $sid=getSid(); $fileid=getfileid($v,$data->data[0]->seed); $one=($data->data[0]->segs->$k); if($k == 'flv' || $k == 'mp4') return "http://f.youku.com/player/getFlvPath/sid/{$sid}_00/st/{$k}/fileid/{$fileid}?K={$one[0]->k}"; continue; } } function get_curl_contents($url, $second = 5){ if(!function_exists('curl_init')) die('php.ini未开启php_curl.dll'); $c = curl_init(); curl_setopt($c,CURLOPT_URL,$url); $UserAgent=$_SERVER['HTTP_USER_AGENT']; curl_setopt($c,CURLOPT_USERAGENT,$UserAgent); curl_setopt($c,CURLOPT_HEADER,0); curl_setopt($c,CURLOPT_TIMEOUT,$second); curl_setopt($c,CURLOPT_RETURNTRANSFER, true); $cnt = curl_exec($c); $cnt=mb_check_encoding($cnt,'utf-8')?iconv('gbk','utf-8//IGNORE',$cnt):$cnt; //字符编码转换 curl_close($c); return $cnt; } function getSid() { $sid = time().(rand(0,9000)+10000); return $sid; } function getkey($key1,$key2){ $a = hexdec($key1); $b = $a ^ 0xA55AA5A5; $b = dechex($b); return $key2.$b; } function getfileid($fileId,$seed) { $mixed = getMixString($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:
$url='http://v.youku.com/v_show/id_XMzg2OTQ3MjQw.html'; echo fetch_youku_flv($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。
