获取推特视频 mp4 网址 [英] Get twitter video mp4 url

问题描述

问题我现在正在使用 twitter API，当帖子包含视频时.Twitter 只返回缩略图 url，而不返回主视频文件 url.Twitter 返回这样的 JSON:

Question I am working with twitter API now and when post includes video. Twitter returns only thumbnails urls and not main video file url. Twitter returns such 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，其他 url 直接重定向到发布.当我使用 php 获取所有信息时，对于 vine.co 有这样的代码:

And first two is jpgs, and other urls redirect straight to post. As I am using php to get all information, for vine.co there was such code:

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

但是 twitter 中没有这样的元标记，我找不到访问视频文件的方法.也许有人知道如何获取 mp4 网址?

But twitter doesn't have such meta tags in and I can't find a way to access video file. Maybe someone know how to get mp4 url?

推荐答案

Twitter 工作人员已声明 此处 他们将不支持使用搜索获取视频.您必须通过对 API 的其他调用来获取视频.

Twitter staff has stated here that they won't be supporting fetching videos using search. You will have to fetch videos with an other call to the API.

假设您使用 $tweet

// 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

array (size=6)
  0 => 
    object(stdClass)[265]
      public 'bitrate' => int 832000
