为什么Youtube V3 Data API只能为此频道返回1个视频结果？
问题：为什么我只能从YouTube Data V3 API采取的下列操作中收到1个视频？ 我试图从（https://www.youtube.com/user/JayLenosGarage/videos）中提取视频的示例频道有多个视频。
我试图从Youtube数据api v3获取特定频道的所有视频及其关联的ID。 我们来看一下JayLenosGarage的例子。
因此，在YouTube上播放此视频（https://www.youtube.com/watch?v=jdqsiFw74Jk&t=757s）后，首先通过查询频道列表api获取“上传”ID，然后使用上传ID运行查询通过播放列表＃列表API，我运行查询通过API浏览器（我也尝试卷曲与API_KEY）JayLenosGarage频道在Youtube如下，并收到以下输出：

要获取频道中所有视频的列表，请使用搜索：列表方法。 它将返回一组符合API请求中指定的查询参数的搜索结果。 默认情况下，搜索结果集标识匹配的视频，频道和播放列表资源，但您也可以将查询配置为仅检索特定类型的资源。
以下是您需要执行的示例请求：
https://www.googleapis.com/youtube/v3/search?part=snippet&channelId=UCQMELFlXQL38KPm8kM-4Adg&maxResults=50&key=YOUR_API_KEY
注意：您只能使用channel.list来获取该channel.list的信息。 它不会返回它里面的视频列表。 由于您已经知道该频道的频道ID，因此请使用Search.list返回该频道内的所有视频。
希望它可以帮助你:)
您必须调用PlaylistItems而不是Playlist 。 我将结果限制为1个结果，但可以将maxResults设置为50。
PlaylistItems＃list api query：
GET https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&playlistId=UUQMELFlXQL38KPm8kM-4Adg&key=<API_KEY>

当然，您也可以使用Search ，但是您必须记住，调用Search花费100个配额， PlaylistItems#list仅花费1个配额。
