Question

我有Youtube视频下载脚本，它提供视频网址但不下载，它在浏览器中打开视频并播放。

    $id = 'jNQXAC9IVRw';//$_GET['v'];
    parse_str(file_get_contents("http://youtube.com/get_video_info?video_id=".$id),$info); 
    $streams = $info['url_encoded_fmt_stream_map'];
    $streams = explode(',',$streams);

    foreach($streams as $stream){
        parse_str($stream,$data);
        echo '<a href="'.$data['url'].'" class="btn btn-success">'.$data['quality'].'</a> ';
        /*echo $data['url'];
        *returns url like this
        *http://r2---sn-2uja-3ipd.googlevideo.com/videoplayback?mime=video%2Fwebm&upn=wdfTtFFSMNA&source=youtube&mt=1484446843&ms=au&expire=1484468585&initcwndbps=187500&ipbits=0&pl=24&itag=43&sparams=dur%2Cid%2Cinitcwndbps%2Cip%2Cipbits%2Citag%2Clmt%2Cmime%2Cmm%2Cmn%2Cms%2Cmv%2Cpl%2Cratebypass%2Csource%2Cupn%2Cexpire&id=o-AGqBaImYFicQvH1J3Tmt4QGqt817uD_Pw-vF9MF8asMy&dur=0.000&mm=31&key=yt6&mn=sn-2uja-3ipd&signature=C38C1D21BC1B7F4658BCEF30DFC94E1ACBE1FC6D.356305D4012AE391A24283CA46950BBCDE7EB7CE&lmt=1418224509434980&mv=m&ratebypass=yes&ip=119.154.139.153
        */
    }

我尝试了很多方法，但没有人按我的意愿工作，我想显示按钮，用户可以在PC上下载他选择的视频格式，如mp4,3gp。
我写了一个在服务器上下载0KB文件的脚本如果由jquery完成也可以。

Answer 1

创建另一个文件download.php将url，file_format发送到该文件

让你的链接= download.php?video_url=https://that_lengthy_url&format=mp4-OR-3gp

的download.php

$format = $_GET['format'];  
$filename = 'video.'.$format;
$url = $_GET['video_url'];

header('Content-Type: application/octet-stream');
header("Content-Transfer-Encoding: Binary"); 
header("Content-disposition: attachment; filename=\"".$filename."\""); 

readfile($url);
exit;
