我正在使用YouTube API V3获取频道的视频，但它返回错误的视频数量。该频道总共有11个视频，但是当我调用API时，我只得到6个(或7个，我不知道情况)，如果我指定maxResults参数为11或更高。
如何解决这个问题?谢谢。我在我的youtube帐户中没有找到任何设置。
为了演示它，通道ID为:UCOjT220XvzZrX6LuZ6GnrGQ当我调用
https://www.googleapis.com/youtube/v3/search?part=snippet&channelId=UCOjT220XvzZrX6LuZ6GnrGQ&maxResults=13&order=date&key=[API_KEY]
我可以得到你提到的11个视频:

由于一些奇怪的原因，当我复制你在评论中发布的URL时，它不起作用，但是当我复制上面发布的channelId并粘贴在你的URL中时，它起作用了(即使它是相同的ID，多么奇怪…)。您可以尝试这样做的另一种方法是使用playlistItems.list并提供您的上传播放列表ID(您可以通过调用channels获得该ID)。列表并指定part=contentDetails)，它以倒叙的时间顺序提供您上传的视频。
