当我尝试使用playlistItems.list列出视频时，我似乎无法在任何地方获取视频的channelId。请注意，视频所有者与播放列表所有者不同。
Here is an example in Google API Explorer
我正在从播放列表中请求一个ID为PLgMGySfO8dl_IybGLflF1QhHwhBkOyZg7的项目。返回的一项是ID为tDHxiDA1Y6s的视频。我希望在某个地方看到ID为UCOfEKi7Qkc3g5XNoQSl3D8Q的频道，但看不到。
我确实将UC1bSfMYJEqh7DTSOsbe_t8Q视为频道ID，但这是播放列表（而非视频）所有者的频道ID。我还注意到在字段编辑器中应该有一个字段snippet.resourceId.channelId，但是即使选择了要包含的字段，如下面的示例结果所示，我也没有得到任何值。
有没有其他方法可以获取视频中包含的频道ID？
这是我得到的结果：

您怀疑，对PlaylistItems的调用会返回播放列表所有者的频道ID。要获取播放列表中视频的原始频道ID，您需要再次调用带有视频ID的视频端点。

他们已将字段“videoOwnerChannelTitle”和“videoOwnerChannelId”添加到代码段部分。 现在您可以直接在 playlistitems 列表请求中获取这两个值。
我刚刚将（使用 Youtube API 的 .NET/C# 库）从 1.30 升级到 1.50。 然后我让它工作。有同样的问题。
