這個(gè)測(cè)試出來(lái)的只是swf文件并不是我們要的flv文件了,后來(lái)參考一站長(zhǎng)的寫法進(jìn)行了改進(jìn),核心代碼如下:

復(fù)制代碼代碼如下:

<?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未開啟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; //字符編碼轉(zhuǎn)換  

    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;  

}  

?>

調(diào)用方法,代碼如下:

復(fù)制代碼代碼如下:

$url='http://v.youku.com/v_show/id_XMzg2OTQ3MjQw.html';

echo fetch_youku_flv($url);

訪問:

復(fù)制代碼代碼如下:

http://xiaomizhou.net/demo/flv.php?url=http://v.youku.com/v_show/id_XMzg2OTQ3MjQw.html

輸出的結(jié)果是:

復(fù)制代碼代碼如下:

http://f.youku.com/player/getFlvPath/sid/138035737110468_00/st/flv/fileid/03000201004F97EF4A2E350467A09DB266E872-5522-225F-DC45-40B4E1F9BE49?K=c2a4327df2bb5a65261d40ea

這個(gè)是可以直接下載的.

希望本文所述對(duì)大家的php程序設(shè)計(jì)有所幫助。
