问题：为什么我从YouTube Data V3 API采取的以下操作中只收到1个视频？我尝试从（https://www.youtube.com/user/JayLenosGarage/videos）中提取视频的示例 Channels 有多个视频 .

我正在尝试从Youtube数据api v3中获取特定 Channels 的所有视频及其相关ID . 让我们使用示例 Channels JayLenosGarage .

所以在YouTube（https://www.youtube.com/watch?v=jdqsiFw74Jk&t=757s）上播放该视频后，首先通过查询 Channels #list api获取"uploads" id，然后使用uploads id通过播放列表运行查询#list api，我通过API资源管理器运行查询（I还在Youtube上为JayLenosGarage Channels 尝试使用API_KEY卷曲，如下所示，并收到以下输出：

Channels #list api查询：

GET https://www.googleapis.com/youtube/v3/channels?part=contentDetails&id=UCQMELFlXQL38KPm8kM-4Adg&key=<API_KEY>

播放列表#list api查询：

    要获取 Channels 内所有视频的列表，请使用Search: list方法 . 它将返回与API请求中指定的查询参数匹配的搜索结果集合 . 默认情况下，搜索结果集标识匹配的视频， Channels 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获取该 Channels 的信息 . 它不会返回其中的视频列表 . 由于您已经知道该 Channels 的 Channels ID，因此请使用Search.list返回该 Channels 内的所有视频 .

    希望它能帮到你:)

    你必须调用 PlaylistItems 而不是 Playlist . 我将结果限制为1个结果，但您可以将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>
{

  }

}

    当然你也可以使用 Search ，但你必须记住，调用 Search 需要100个配额，而 PlaylistItems#list 只需要1个配额 .
