Youtube API播放列表不返回播放列表

Question

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

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

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

我使用的查询：

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

它不会返回视频时，我试图目标在这些渠道播放列表，以及使用指定的播放列表ID。我可以看到，这些频道，播放列表和视频是公开的和可搜索的。

为什么API不应该返回我缺少的这个播放列表呢？

谢谢你的帮助。

如果您检查所提供频道的播放列表页，您会发现在那里发布的所有播放列表实际上都不是来自频道--这些列表是由YouTube本身添加/生成的。

示例：

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

普通播放列表(属于频道)应该有ID，如下所示：

PL3tRBEVW0hiB5KKP9gs_AkW8J4dOvbdPN

通过使用YouTube数据API，您可以测试结果：

网址：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，您将得到以下结果：
