php - 将视频上传到特定的播放列表

Question

我正在使用youtube数据API将视频上传到我的 channel 。效果很好，但是当我上传视频时，它会上传到我的 channel 中。我希望它在给定的播放列表中上传。(我已经创建了一些播放列表)。有什么办法可以在以下代码中给playlistId？我不想使用playlistitem.insert。

根据此SO answer，您不能将视频直接上传到播放列表。通常，上传视频时，视频会重定向到您的 channel 。将其上传到 channel 后，您现在可以将其放入播放列表中。

如果视频已经上传，则可以遵循此Adding a video to a playlist文档。您可以使用VideoEntry对象将视频添加到播放列表。

这是一个示例代码，它使用已知的条目ID检索VideoEntry对象，然后将其添加到与PlaylistListEntry对象相对应的播放列表中。由于请求未指定视频在播放列表中出现的位置，因此将新视频添加到播放列表的末尾。

$postUrl = $playlistToAddTo->getPlaylistVideoFeedUrl();
// video entry to be added
$videoEntryToAdd = $yt->getVideoEntry('4XpnKHJAok8');

// create a new Zend_Gdata_PlaylistListEntry, passing in the underling DOMElement of the VideoEntry
$newPlaylistListEntry = $yt->newPlaylistListEntry($videoEntryToAdd->getDOM());

// post
try {
  $yt->insertEntry($newPlaylistListEntry, $postUrl);
} catch (Zend_App_Exception $e) {
  echo $e->getMessage();
}
