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： 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： 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？… 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. 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
*
* @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,CURLOPT_MAXREDIRS,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'));
