获取Twitter视频MP4链接

phpvideotwitter
7

问题：我现在正在使用Twitter API，当推文包含视频时，Twitter仅返回缩略图URL而不是主视频文件的URL。Twitter返回这样的JSON：

["media_url"]=> string(86) "http://pbs.twimg.com/ext_tw_video_thumb/../pu/img/p1R5iC_7fN-lqNuK.jpg" 
["media_url_https"]=> string(87) "https://pbs.twimg.com/ext_tw_video_thumb/.../pu/img/p1R5iC_7fN-lqNuK.jpg" 
["url"]=> string(22) "http://t.co/UViL9KykF*" 
["expanded_url"]=> string(63) "http://twitter.com/.../status/..../video/1"

前两个是jpg格式的图片，其他的url直接跳转到帖子页面。 由于我使用php获取所有信息，对于vine.co网站，代码如下：

$dom = new DomFinder($media_url);
$video_cell = $dom->find("//meta[@property='twitter:player:stream']", 'content');

但是 Twitter 在 <head> 中没有这样的 meta 标签，而且我找不到访问视频文件的方法。也许有人知道如何获取 MP4 URL？

Twitter员工在这里表示，他们不会支持使用搜索获取视频。您需要通过API的其他调用来获取视频。

假设您使用search/tweets获取了一个推文，并将其保存在$tweet中。

// Check if tweet has media
if (!empty($tweet->entities->media)) {
    $searchArray = array(
        "id" => $tweet->id, // id of the tweet we just fetched
        "include_entities" => true // tells twitter API to return videos and stuff
    );

    // Get extended_entities
    $extendedEntities = $connection->get("statuses/show", $searchArray);
    foreach($extendedEntities->extended_entities->media as $media){
        var_dump($media->video_info->variants);
    }
}

示例结果

在响应中添加选项tweet_mode:'extended'以获取extended_entities对象。响应中的此路径将具有视频URL：extended_entities.media[0].video_info.variants 示例：
[
  {
    content_type: 'application/x-mpegURL',
    url: 'https://video.twimg.com/ext_tw_video/1358226.........'
  },
  {
    bitrate: 832000,
    content_type: 'video/mp4',
    url: 'https://video.twimg.com/ext_tw_video/1358226.........'
  },
  {
    bitrate: 256000,
    content_type: 'video/mp4',
    url: 'https://video.twimg.com/ext_tw_video/1358226.........'
  }
