zend-framework - 从 Youtube API（zend 框架）检索 URL 和缩略图

Question

我试图用zend显示一个视频播放列表，但是在捕捉到播放列表信息之后，我不知道我需要做什么才能找到缩略图或缩略图的url。

这是我的代码：

require_once 'Zend/Loader.php'; // the Zend dir must be in your include_path
Zend_Loader::loadClass('Zend_Gdata_YouTube');

 $yt = new Zend_Gdata_YouTube();
 $playlistListFeed = $yt->getPlaylistListFeed('admaltais');

 //step 1: show the playlist name and his URL
 foreach ($playlistListFeed as $playlistEntry) 
 {
    echo $playlistEntry->title->text . "</br></br>";
    echo $playlistEntry->getPlaylistVideoFeedUrl() . "</br></br>";
 }


 //step 2: parse the playlist
 $feedUrl = $playlistEntry->getPlaylistVideoFeedUrl();
 $playlistVideoFeed = $yt->getPlaylistVideoFeed('http://gdata.youtube.com/feeds/api/playlists/B15D7FD35D3814A5');

 foreach ($playlistVideoFeed as $playlistVideoFeedEntry) 
 {
   echo $playlistVideoFeedEntry->title->text . "</br></br>";
   //here i want to retrieve the infos
   //var_dump($playlistVideoFeedEntry);
 }

Answer 1

至于检索缩略图 URL，请查看http://markmail.org/message/heekjb62yxf4skut上的getMediaArray()函数。

根据您的代码，您将执行以下操作：

$media = getMediaArray($playlistEntry);
$thumbnail = isset($media['thumbnail']) ? $media['thumbnail'] : false;

这对我有用，我不确定是否有更好的方法，但这是我现在能找到的最好的方法。
