使用 YouTube Data API v3 从播放列表中删除视频

我正在构建一个应用程序，用户可以使用该应用程序通过拖放创建播放列表.我希望他们能够从播放列表中删除视频.但我对文档感到困惑.

I'm building an application with which users can create playlists through drag and drop. I want them to be able to remove videos from a playlist. But I get confused with the docs.

我正在使用 youtube api php 客户端库.请记住，用户已登录.

I'm using the youtube api php client library. Keep in mind that the user is logged in.

$youtubeService = new Google_YouTubeService($client);
$playlistItems = $youtubeService->playlistItems;
$deleteVid = $playlistItems->delete($videocode);

这是来自客户端库的删除函数:

And this is the delete function from the client library :

 /**
 * Deletes a playlist item. (playlistItems.delete)
 *
 * @param string $id The id parameter specifies the YouTube playlist item ID for the playlist item that is being deleted. In a playlistItem resource, the id property specifies the playlist item's ID.
 * @param array $optParams Optional parameters.
 */

public function delete($id, $optParams = array()) {
  $params = array('id' => $id);
  $params = array_merge($params, $optParams);
  $data = $this->__call('delete', array($params));
  return $data;
}

没有任何地方可以指定从哪个播放列表中删除视频.有谁知道如何做到这一点?其他 playlistItem 函数使用 Google_PlaylistItem 对象作为参数.但这只是视频代码的一个字符串......太奇怪了，我自己无法弄清楚这一点.

There's nowhere, where I can specify which playlist to delete the video from. Does anyone have an idea how to do this? The other playlistItem functions use a Google_PlaylistItem object as a parameter. But this one only a string for the videocode... So weird, can't figure this one out on my own.

任何帮助将不胜感激.
