PHP嗅探youku视频的真实flv文件地址！

这个是借力打力，只是抓去朋友网的内容！！！

不过相当好用哦！

看代码：

代码如下

复制代码

$videourl='http://v.youku.com/v_show/id_XMjA5MjQ0OTQ0.html';
function get_content($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：

代码如下

复制代码

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	复制代码
$url='http://v.youku.com/v_show/id_XMzg2OTQ3MjQw.html'; echo fetch_youku_flv($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
