从PHP中获取Vimeo的直接链接视频 [英] Get direct link videos from Vimeo in PHP
问题描述
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关联的签名。这个信息存储在一个JavaScript变量中，就在之前的一行520下：
window.addEvent（'domready'，function（）{
然后，当您单击播放时，HTML5播放器读取此变量并发送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
如果此网址未打开，则打开 http://vimeo.com/22439234 ，这将返回HTTP代码200，并显示一条错误消息。
如果此URL打开，正确的IP地址，标题位置重定向到链接视频文件：
http://av.vimeo.com/XXX/XX/XXXX.mp4?aksessionid=XXXX&token=XXXXX_XXXXXXXXX
当我构建此链接 http：//player.vimeo.com/play_redirect？... 手动（右键单击 >source code>line 520）它的工作原理。
但是使用PHP和regex，它返回 HTTP代码200 有一个错误消息。
为什么？
从我的观察，Vimeo不检查标题HTTP请求 http：// player.vimeo.com/play_redirect？...
GET ， HEAD ，带有Cookie，无Cookie，引荐来源等...不会更改。
使用PHP ，我使用函数 file_get_contents（）和 get_headers（）。
<？php
函数getVimeo（$ id）{
$ content = file_get_contents（'http://vimeo.com/ 的$ id）;
if（preg_match（'＃document\.getElementById\（\'player _（。+）\\\
'i'，$ content，$ scriptBlock）== 0）
return 1;
preg_match（'＃timestamp：（[0-9] +）＃i'，$ scriptBlock [1]，$ matches）;
$ timestamp = $ match [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）。
- 解析内容以从数据中查找和提取值-config-url
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
直接链接的SD质量视频。
这是我简单的类，那
class VideoController
{
/ **

public $ vimeoQualityPrioritet = array（'sd'，'hd'，'mobile'）;
/ **

{

$ videoInfo = $ this-> getVimeoVideoInfo（$ url）;
if（$ videoInfo&& $ videoObject = $ this-> getVimeoQualityVideo（$ videoInfo-> request-> files））
{
$ result = $ videoObject-> ;网址;
}
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 =1.0encoding =UTF-8？>'。\\\
$ 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;
}
/ **

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

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_USERAGENT，'spider'）;
$ content = curl_exec（$ ch）;
curl_close（$ ch）;
return $ content;
}
}
使用：
$ video = new VideoController;
var_dump（$ video-> getVimeoDirectUrl（'http://vimeo.com/90747156'））;
I want a direct link to videos from Vimeo with a PHP script. I managed to find them manually, but my PHP script does not work. Here is the initiative: For example I took this video: http://vimeo.com/22439234
When you go on the page, Vimeo generates a signature associated with the current timestamp and this video. This information is stored in a JavaScript variable, around line 520 just after:
window.addEvent ('domready', function () {
Then when you click Play, the HTML5 player reads this variable and sends an HTTP request:
http:// player.vimeo.com/play_redirect?clip_id=37111719&sig={SIGNATURE}&time={TIMESTAMP}&quality=sd&codecs=H264,VP8,VP6&type=moogaloop_local&embed_location=
But it also works with:
http:// player.vimeo.com/play_redirect?clip_id=37111719&sig={SIGNATURE}&time={TIMESTAMP}&quality=sd
If this URL does not open with the IP address that opened http://vimeo.com/22439234, this returns the HTTP code 200 with an error message.
If this URL is opened with the correct IP address, the header "Location" redirects to link to the video file:
http://av.vimeo.com/XXX/XX/XXXX.mp4?aksessionid=XXXX&token=XXXXX_XXXXXXXXX
When I build this link http://player.vimeo.com/play_redirect?... manually ("right click"> "source code"> "line 520") it works.
But with PHP and regex it returns the HTTP code 200 with an error message.
Why ?
From my observations, Vimeo does not check the headers of the HTTP request for http:// player.vimeo.com/play_redirect?...
GET, HEAD, with cookies, without cookies, referrer etc. ... does not change.
With PHP, I use the function file_get_contents() and 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));
}
The algorithm looks like this:
- Input data: vimeoUrl.
- content = getRemoteContent(vimeoUrl).
- Parse content to find and extract the value from data-config-url attribute.
- Navigate to data-config-url and load the content as JSON Object: $video = json_decode($this->getRemoteContent($video->getAttribute('data-config-url')));
- Return $video->request->files->h264->sd->url — this will return a direct link for SD quality video.
Here is my simple class, that working for this moment.
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;
}
}
Using:
$video = new VideoController;
var_dump($video->getVimeoDirectUrl('http://vimeo.com/90747156'));
