Question

我试着用这个：

https://www.googleapis.com/youtube/v3/playlistItems?part=snippet,contentDetails&{playlist_id}&key={key}&maxResults=50

和

https://www.googleapis.com/youtube/v3/search?part=snippet&q=YouTube+Data+API&type=video&videoCaption=closedCaption&key={key}&maxResults=50

它在文档中说它是contentDetails.duration但这似乎并不存在于我收到的数据中。

Answer 1

如果您选中Ember docs，则会看到它不在该响应中。

这实际上是一个功能请求：search resource

您可以跟进该问题。

Answer 2

要获取播放列表中视频的详细信息，您需要针对该播放列表中包含snippet和contentDetails值的每个视频点按Videos.list方法part：

请求：

HTTP GET https://www.googleapis.com/youtube/v3/videos?part=snippet%2C+contentDetails&id=AKiiekaEHhI&key={YOUR_API_KEY}

回复（id=AKiiekaEHhI）：

  }
 ]
}

可以在duration词典中找到内容的持续时间作为contentDetails键的对象。

categoryId映射到您的视频类别，您必须使用VideoCategories.list方法进行查找。

请求：

HTTP GET https://www.googleapis.com/youtube/v3/videoCategories?part=snippet&id={CATEGORY_ID}&key={YOUR_API_KEY}

回复（针对id=20：

）

   }

}

title字典中snippet键的对象返回所需视频类别的字符串值。

使用YouTube API v3，我如何才能访问内容持续时间和流派？通过搜索或获取详细信息
