从PHP获取Vimeo的直接链接视频

我希望使用PHP脚本直接链接来自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,我拍摄了这段视频:http://vimeo.com/22439234

当您进入该页面时,Vimeo会生成与当前时间戳和此视频相关联的签名。这些信息存储在一个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HTTP代码200,并显示错误消息。

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&token=XXXXX_XXXXXXXXX

当我手动构建此链接http://player.vimeo.com/play_redirect?...(“右键单击”>“源代码”>“第520行”)时,它可以正常工作。

但是使用PHP和regex它会返回HTTP code 200,并显示错误消息。

为什么?

根据我的观察,Vimeo不检查http:// player.vimeo.com/play_redirect?...的HTTP请求的标头 GETHEAD,带有Cookie,没有Cookie,推荐人等......不会改变。

使用PHP,我使用函数file_get_contents()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', $scriptBlock[1], $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并将内容加载为JSON对象: $ video = json_decode($ this-&gt; getRemoteContent($ video-&gt; getAttribute(&#39; data-config-url&#39;)));
  • 返回$ video-&gt; request-&gt; files-&gt; h264-&gt; sd-&gt; 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。

class VideoController
{

    /**
     * @var array Vimeo video quality priority
     */
    public $vimeoQualityPrioritet = array('sd', 'hd', 'mobile');

    /**
     * @var string Vimeo video codec priority
     */
    public $vimeoVideoCodec = 'h264';

    /**
     * Get direct URL to Vimeo video file

     * @return string file URL
     */
    public function getVimeoDirectUrl($url)
    {
        $result = '';
        $videoInfo = $this->getVimeoVideoInfo($url);
        if ($videoInfo && $videoObject = $this->getVimeoQualityVideo($videoInfo->request->files))
        {
            $result = $videoObject->url;
        }
        return $result;
    }

    /**

    public function getVimeoVideoInfo($url)
    {
        $videoInfo = null;
        $page = $this->getRemoteContent($url);
        $dom = new \DOMDocument("1.0", "utf-8");
        libxml_use_internal_errors(true);
        $dom->loadHTML('<?xml version="1.0" encoding="UTF-8"?>' . "\n" . $page);
        $xPath = new \DOMXpath($dom);
        $video = $xPath->query('//div[@data-config-url]');
        if ($video)
        {
            $videoObj = json_decode($this->getRemoteContent($video->item(0)->getAttribute('data-config-url')));
            if (!property_exists($videoObj, 'message'))
            {
                $videoInfo = $videoObj;
            }
        }
        return $videoInfo;
    }

    /**
     * Get vimeo video object

    public function getVimeoQualityVideo($files)
    {
        $video = null;
        if (!property_exists($files, $this->vimeoVideoCodec) && count($files->codecs))
        {
            $this->vimeoVideoCodec = array_shift($files->codecs);
        }
        $codecFiles = $files->{$this->vimeoVideoCodec};
        foreach ($this->vimeoQualityPrioritet as $quality)
        {
            if (property_exists($codecFiles, $quality))
            {
                $video = $codecFiles->{$quality};
                break;
            }
        }
        if (!$video)
        {
            foreach (get_object_vars($codecFiles) as $file)
            {
                $video = $file;
                break;
            }
        }
        return $video;
    }

    /**
     * Get remote content by URL
     *

     * @return string result content

    public function getRemoteContent($url)
    {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
        curl_setopt($ch, CURLOPT_TIMEOUT, 20);
        curl_setopt($ch, CURLOPT_HEADER, false);
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

        $content = curl_exec($ch);

        curl_close($ch);

        return $content;
    }

}

使用:

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

尝试为每个请求的标头添加有效的用户代理。 为此,您必须使用cURL或HttpRequest而不是file_get_contents()。

经过这样的操作后,我得到了一个用于下载视频文件的工作链接。

这是我的代码:

function getVimeo($id) {
    // get page with a player
    $queryResult = httpQuery('http://vimeo.com/' . $id);
    $content = $queryResult['content'];

    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', $scriptBlock[1], $matches);
    $signature = $matches[1];

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

    // make the request for getting a video url
    #print_r(get_headers($url, 1));
    $finalQuery = httpQuery($url);
    return $finalQuery['redirect_url'];
}
// make queries via CURL
function httpQuery($url) {
    $options = array(
        CURLOPT_USERAGENT => 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.19 (KHTML, like Gecko) Ubuntu/12.04 Chromium/18.0.1025.168 Chrome/18.0.1025.168 Safari/535.19',
        CURLOPT_RETURNTRANSFER => true,
    );
    $ch = curl_init($url);
    curl_setopt_array($ch, $options);
    $content = curl_exec($ch);
    $info = curl_getinfo($ch);
    curl_close($ch);
    $result = $info;
    $result['content'] = $content;

    return $result;
}

echo getVimeo(22439234);
