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:
代码如下:
$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:
代码如下:
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,$url);
$UserAgent=$_SERVER['HTTP_USER_AGENT'];
curl_setopt($c,CURLOPT_USERAGENT,$UserAgent);
curl_setopt($c,0);
curl_setopt($c,CURLOPT_TIMEOUT,$second);
curl_setopt($c,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:
代码如下:
