如何使用YouTube v3 API检索YouTube视频的标签？

Question

我想使用YouTube API的v3检索特定YouTube视频的标签。

我可以将包含此请求的视频检索到搜索端点https://www.googleapis.com/youtube/v3/search?part=snippet&maxResults=1&q=cats&type=video&key= {YOUR_API_KEY}。

现在我点击了视频端点，试图从上面的查询中获取视频的标签。 https://www.googleapis.com/youtube/v3/videos?id=IytNBm8WA1c&part=snippet&key= {} YOUR_API_KEY

响应，

{ 
"kind": "youtube#videoListResponse", 
"etag": "\"PMn2rAVTRiZHkX45qiqfcLZoTXM/rYBuk4KeZFmSMoiSuaXfy6-Pm28\"", 
"items": [

API浏览器的这一要求 - https://developers.google.com/apis-explorer/#p/youtube/v3/youtube.videos.list?id=IytNBm8WA1c&part=snippet&_h=3&

即使我授权这一请求，我得到相同的结果。虽然，如果被授权的帐户拥有该视频，它将返回标签。

如何获取我拥有的视频的标签而不要求最终用户授权其帐户？这个实现是JS的客户端。

根据https://developers.google.com/youtube/v3/docs/videos/list似乎在YouTube API的最新版本现在返回标签：

比从未

https://www.googleapis.com/youtube/v3/videos?key={API-key}&fields=items(snippet(title,description,tags))&part=snippet&id={video_id}

不幸的是，目前你只能在你验证自己的频道所有者获得与标记的视频。搜索用于工作的标签，但在当前的V2实现中使用is broken。
