从PHP获取Vimeo的直接链接视频

Question

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,我拍摄了这个视频: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未使用打开的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http://player.vimeo.com/play_redirect?...手动构建此链接时("右键单击">"源代码">"第520行"),它可以正常工作.

但是使用PHP和正则表达式,它会返回HTTP code 200错误消息.

为什么？

从我的观察,Vimeo的不检查HTTP请求的头http:// player.vimeo.com/play_redirect?... GET,HEAD与饼干,没有cookies,引用等等......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', $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));
    }

该算法如下所示：

\n\n

\n
• 输入数据：vimeoUrl。
\n
• 内容 = getRemoteContent(vimeoUrl).
\n
• 解析内容以从 data-config-url\nattribute 中查找并提取值。
\n
• 导航到 data-config-url 并将内容加载为 JSON 对象：\n$video = json_decode($this->getRemoteContent($video->getAttribute(\'data-config-url\')));
\n
• 返回 $video->request->files->h264->sd->url \xe2\x80\x94 这将返回 SD 质量视频的直接链接。

这是我的简单课程，目前正在使用。

class VideoController\n{\n\n    /**\n     * @var array Vimeo video quality priority\n     */\n    public $vimeoQualityPrioritet = array(\'sd\', \'hd\', \'mobile\');\n\n    /**\n     * @var string Vimeo video codec priority\n     */\n    public $vimeoVideoCodec = \'h264\';\n\n    /**\n     * Get direct URL to Vimeo video file\n     * \n     * @param string $url to video on Vimeo\n     * @return string file URL\n     */\n    public function getVimeoDirectUrl($url)\n    {\n        $result = \'\';\n        $videoInfo = $this->getVimeoVideoInfo($url);\n        if ($videoInfo && $videoObject = $this->getVimeoQualityVideo($videoInfo->request->files))\n        {\n            $result = $videoObject->url;\n        }\n        return $result;\n    }\n\n    /**\n     * Get Vimeo video info\n     * \n     * @param string $url to video on Vimeo\n     * @return \\stdClass|null result\n     */\n    public function getVimeoVideoInfo($url)\n    {\n        $videoInfo = null;\n        $page = $this->getRemoteContent($url);\n        $dom = new \\DOMDocument("1.0", "utf-8");\n        libxml_use_internal_errors(true);\n        $dom->loadHTML(\'<?xml version="1.0" encoding="UTF-8"?>\' . "\\n" . $page);\n        $xPath = new \\DOMXpath($dom);\n        $video = $xPath->query(\'//div[@data-config-url]\');\n        if ($video)\n        {\n            $videoObj = json_decode($this->getRemoteContent($video->item(0)->getAttribute(\'data-config-url\')));\n            if (!property_exists($videoObj, \'message\'))\n            {\n                $videoInfo = $videoObj;\n            }\n        }\n        return $videoInfo;\n    }\n\n    /**\n     * Get vimeo video object\n     * \n     * @param stdClass $files object of Vimeo files\n     * @return stdClass Video file object\n     */\n    public function getVimeoQualityVideo($files)\n    {\n        $video = null;\n        if (!property_exists($files, $this->vimeoVideoCodec) && count($files->codecs))\n        {\n            $this->vimeoVideoCodec = array_shift($files->codecs);\n        }\n        $codecFiles = $files->{$this->vimeoVideoCodec};\n        foreach ($this->vimeoQualityPrioritet as $quality)\n        {\n            if (property_exists($codecFiles, $quality))\n            {\n                $video = $codecFiles->{$quality};\n                break;\n            }\n        }\n        if (!$video)\n        {\n            foreach (get_object_vars($codecFiles) as $file)\n            {\n                $video = $file;\n                break;\n            }\n        }\n        return $video;\n    }\n\n    /**\n     * Get remote content by URL\n     * \n     * @param string $url remote page URL\n     * @return string result content\n     */\n    public function getRemoteContent($url)\n    {\n        $ch = curl_init();\n        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);\n        curl_setopt($ch, CURLOPT_TIMEOUT, 20);\n        curl_setopt($ch, CURLOPT_HEADER, false);\n        curl_setopt($ch, CURLOPT_URL, $url);\n        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);\n        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);\n        curl_setopt($ch, CURLOPT_MAXREDIRS, 10);\n        curl_setopt($ch, CURLOPT_USERAGENT, \'spider\');\n        $content = curl_exec($ch);\n\n        curl_close($ch);\n\n        return $content;\n    }\n\n}\n

\n\n

使用：

\n\n

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

尝试将有效的用户代理添加到每个请求的标头中。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);
