算法如下：
- 输入数据：vimeoUrl。
- content = getRemoteContent(vimeoUrl)。
- 解析内容以从 data-config-url 中查找和提取值
属性。
- 导航到 data-config-url 并将内容加载为 JSON 对象：
$video = json_decode($this->getRemoteContent($video->getAttribute('data-config-url')));
- 返回 $video->request->files->h264->sd->url — 这将返回一个
标清质量视频的直接链接。
这是我的简单课程，目前正在工作：
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
*
* @param string $url to video on Vimeo
* @return string file URL
*/
public function getVimeoDirectUrl($url)
{
$result = '';
$videoInfo = $this->getVimeoVideoInfo($url);
if ($videoInfo && $videoObject = $this->getVimeoQualityVideo($videoInfo->request->files))
{
$result = $videoObject->url;
}
return $result;
}
/**
* Get Vimeo video info
*
* @param string $url to video on Vimeo
* @return \stdClass|null result
*/
public function getVimeoVideoInfo($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
*
* @param stdClass $files object of Vimeo files
* @return stdClass Video file object
*/
public function getVimeoQualityVideo($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
*
* @param string $url remote page URL
* @return string result content
*/
public function getRemoteContent($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);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_MAXREDIRS, 10);
curl_setopt($ch, CURLOPT_USERAGENT, 'spider');
$content = curl_exec($ch);
curl_close($ch);
return $content;
}
}
使用：
$video = new VideoController;
var_dump($video->getVimeoDirectUrl('http://vimeo.com/90747156'));
