Question

我想列出YouTube上可用的所有电影（即可通过// @outube.com/movies获得的电影）。我可以看到如何查询那些使用API V2，但这有1000个响应的限制。

使用V3 api，我可以看到电影的类别为id 30，但我无法弄清楚如何获得这个类别的所有电影。唯一的类别查询似乎会搜索指南类别，这些类别不同。

有关如何获取此列表的任何线索？如果可以，请帮忙！

Answer 1

我相信您可以获取与电影相关的自动生成频道，并使用其ID获取与此频道相关的播放列表，最后获取此播放列表中的项目（视频..），这些视频必须是与所选频道的电影：

以这种方式，您可以根据需要创建视频列表

Answer 2

这是我目前的答案 - 仍在努力，所以我还没有接受它

我计算出电影的categoryId是30.然后我使用这个categoryId搜索视频，然后查询字符串“movie”（因为我需要放东西）。这提供了超过1000个结果，并且即使使用v3 api，Google也会将查询限制为1000个结果。

所以我需要对查询进行分区。我已经能够使用publishedBefore和publishedAfter执行此操作。请注意，这些是上传日期而非发布日期。

这给了我一个电影列表。

这是一个示例查询 https://www.googleapis.com/youtube/v3/search?nextPageToken=CDIQAA&publishedBefore=2010-02-01T00%3A00%3A00Z&maxResults=50&q=movie&videoCategoryId=30&part=id%2Csnippet&key=yourAPIKeyHere&type=video&publishedAfter=2010-01-01T00%3A00%3A00Z

获得电影ID后，我会查询各个电影ID

https://www.googleapis.com/youtube/v3/videos?part=snippet%2CcontentDetails&maxResults=50&id=O7cSKNevYQc%2CN84-SoboM6c%2C9K_WO3lqDSc%2CWTJP0Z-bknc%2CdF9hwjeRbGE%2CPnefvJ9T1N0%2CDuM6B4yKgTU%2C0tI8iP2f58I%2Cr4lNJEnY0FA%2COFnMrx6yEcA%2CmUZUAeqOmbg%2CDjq0tHK-KTo%2CkY44nxk0qjg%2CcLYkUR5MY14%2CTZpcfYOOEXA%2C-0jA9DMX8Qs%2C2TQDV1m4X2s%2CBh3Tye1OQvk%2Ct5IwjMDVNz4%2CkOi88X6xeKg%2Ck53CuaAUtik%2CNaRuenqLb9g%2Cn9h-0Wgix7Q%2CQG8SiW2a_l0%2Cmk-D66Z1Ydg%2ClvmwofckpNc%2CgRQK4fTXfBM%2CPZHgLy48R3Q%2CwczeO0DVM0g%2CTpMDTG3dEYE%2C6JI8pN7BqEQ%2COv9yllk3hsY%2CsN09sfLPu0g%2CbfhLYJGN948%2CPiWusdK75Ys%2CeE5jh0YwTCY%2C_cIw3vr2Q18%2CSA4xg_k0aqI%2CUZdha0zTM6w%2CwUdkDSIBw94%2CAhR-LDSIOaI%2C1XMt40vJayU%2C83fPx5-aUL8%2CmJLjaKzu7PQ%2CZvj_zRGnwU0%2CtyIPMd7JXOA%2CToE10sC36KQ%2COVKXjOW6cD8%2CLPW1cXVjMrg&key=LALALA

我仍然需要通过查看结果中的以下json来过滤结果

  "contentDetails": {
    "duration": "PT1H35M14S",
    "regionRestriction": {
     "allowed": [
      "US"
     ]
    }

不幸的是，这仍然没有给我电影年或导演（这对于制作实际上是哪部电影很有用），或价格（你知道，人们觉得有趣）
