这篇文章主要介绍了PHP获取youku视频真实flv文件地址的方法,可实现针对youku视频真实地址的解析功能,非常具有实用价值,需要的朋友可以参考下

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。
