Youtube API 播放列表未返回播放列表

Question

我正在使用 Youtube API 的播放列表端点从特定频道获取播放列表，但它不适用于以下频道：

https://www.youtube.com/channel/UCX5fyLRcU05DMa2OVu-qFEQ

https://www.youtube.com/channel/UCwm2mdiUXApmL5bCxHtgJIA

我正在使用的查询：

https://www.googleapis.com/youtube/v3/playlists?channelId=UCwm2mdiUXApmL5bCxHtgJIA&part=snippet&order=date&maxResults=50&key=YOUR_API_KEY

https://www.googleapis.com/youtube/v3/playlists?channelId=UCX5fyLRcU05DMa2OVu-qFEQ&part=snippet&order=date&maxResults=50&key=YOUR_API_KEY

当我尝试使用特定的播放列表 ID 定位这些频道中的播放列表时，它不会 return 视频。我可以看到这些频道、播放列表和视频 public 并且可以搜索。

有什么理由 API 不应该 return 我丢失的这个播放列表吗？

感谢您的帮助。

Answer 1

如果您查看 playlist page of the channel you provided，您会发现那里发布的所有播放列表并非真正来自该频道 - 那些 added/generated 由 YouTube 本身发布。

示例：

https://www.youtube.com/playlist?list=OLAK5uy_nvZSUlZB8qwifPgIVCoEulF4VyErdBX48

一个普通的播放列表（属于频道）的ID应该如下：

PL3tRBEVW0hiB5KKP9gs_AkW8J4dOvbdPN

通过使用 YouTube 数据 API，您可以测试结果：

URL: https://youtube.googleapis.com/youtube/v3/playlists?part=id%2Csnippet%2Cstatus&id=OLAK5uy_nvZSUlZB8qwifPgIVCoEulF4VyErdBX48&key=[YOUR_API_KEY]

结果：

当您查询一个普通播放列表（属于该频道）时，您将得到这些结果：
