从PHP获取Vimeo的直接链接视频

我希望通过 PHP脚本直接链接到Vimeo的视频.
我设法手动找到它们,但我的PHP脚本不起作用.
这是倡议：
例如,我拍了这个视频： http://vimeo.com/22439234

当您进入页面时,Vimeo会生成与当前时间戳和此视频相关联的签名.此信息存储在一个JavaScript变量中,紧接在第520行之后：
window.addEvent(‘domready’,function(){

然后,当您单击“播放”时,HTML5播放器将读取此变量并发送HTTP请求：

http:// player.vimeo.com/play_redirect?clip_id=37111719&sig={SIGNATURE}&time={TIMESTAMP}&quality=sd&codecs=H264,VP8,VP6&type=moogaloop_local&embed_location=

但它也适用于：

http:// player.vimeo.com/play_redirect?clip_id=37111719&sig={SIGNATURE}&time={TIMESTAMP}&quality=sd

如果此URL未使用打开http://vimeo.com/22439234的IP地址打开,则会返回带有错误消息的HTTP代码200.

如果使用正确的IP地址打开此URL,则标题“位置”会重定向以链接到视频文件：
http://av.vimeo.com/XXX/XX/XXXX.mp4?aksessionid=XXXX\u0026amp;token=XXXXX_XXXXXXXXX

当我建立这个链接http：//player.vimeo.com/play_redirect？…手动(“右键单击”>“源代码”>“520行”)它可以工作.

但是使用PHP和regex,它会返回带有错误消息的HTTP代码200.

为什么？

根据我的观察,Vimeo没有检查http：// player.vimeo.com/play_redirect的HTTP请求的标头？…
GET,HEAD,带饼干,没有cookies,推荐人等……不会改变.

使用PHP,我使用函数file_get_contents()和get_headers().

<?PHP
    function getVimeo($id) {

    $content = file_get_contents('http://vimeo.com/'.$id);

    if (preg_match('#document\.getElementById\(\'player_(.+)\n#i',$content,$scriptBlock) == 0)
        return 1;

    preg_match('#"timestamp":([0-9]+)#i',$scriptBlock[1],$matches);
    $timestamp = $matches[1];
    preg_match('#"signature":"([a-z0-9]+)"#i',$matches);
    $signature = $matches[1];

    $url = 'http://player.vimeo.com/play_redirect?clip_id='.$id.'&sig='.$signature.'&time='.$timestamp.'&quality=sd';

    print_r(get_headers($url,1));
    }

算法如下所示：

>输入数据：vimeoUrl.
> content = getRemoteContent(vimeoUrl).
>解析内容以从data-config-url中查找并提取值
 属性.
>导航到data-config-url并将内容作为JSON对象加载：
$video = json_decode($this-> getRemoteContent($video-> getAttribute(‘data-config-url’)));
>返回$video-> request-> files-> h264-> sd-> url – 这将返回一个
SD质量视频的直接链接.

这是我的简单课程,适合这一刻.

使用：

$video = new VideoController;
var_dump($video->getVimeoDirectUrl('http://vimeo.com/90747156'));
