如何使用 YouTube V3 API 获取所有电影（非视频）

Question

我想列出 YouTube 上所有可用的电影（即通过 //youtube.com/movies 提供的电影）。我可以了解如何使用 API V2 查询这些内容，但这有 1000 个响应的限制。

使用 V3 api，我可以看到电影类别的 id 为 30，但我不知道如何获取该类别的所有电影。唯一的类别查询似乎是在不同的指南类别上进行搜索。

关于如何获得此列表的任何线索？如果可以的话请帮忙！

Answer 1

我相信您可以获取与电影相关的自动生成的频道，并使用它们的 id 获取与该频道相关的播放列表，最后从该播放列表中获取项目（视频..），那一定是与该电影的电影相关的视频选定频道：
