获取 YouTube 中的音乐流派 [英] Get the music genres in YouTube
问题描述
当我们查看 YouTube 页面并单击音乐"时，我们可以在说唱"、摇滚"、乡村"等不同流派中看到它们.
When we view the YouTube page, and click Music, we are able to see them on different genre's like "Rap", "Rock", "Country", etc.
如何使用 YouTube API 检索此数据(视频的类型列表).
How can I retrieve this data (the genre-wise listing of videos) using the YouTube Apis.?
推荐答案
一种方法是使用主题 API 与 API 的 V3 集成.查看videos.list() API 调用.插入这些值:
One way to do this is using the Topics API integration with V3 of the API. Take a look at the videos.list() API call. Plug in these values:
- 部分:主题详细信息
- id:fWNaR-rxAic
- 字段:items/topicDetails/topicIds
该视频的 ID 对应于 Carly Rae Jepsen 的Call Me Maybe".当您查看 JSON 响应时，您会看到一个主题 ID 列表:
The ID of that video corresponds to Carly Rae Jepsen's "Call Me Maybe". When you look at the JSON response, you'll see a list of topic IDs:
[ "/m/015f7","/m/0h55y27","/m/0gkxzs6","/m/064t9" ]
[ "/m/015f7", "/m/0h55y27", "/m/0gkxzs6", "/m/064t9" ]
这些是 Freebase 机器 ID.然后，您将进行 Freebase API 调用以检索有关该特定主题的信息.例如，/m/064t9 对应于流行音乐".
These are Freebase machine IDs. You would then make a Freebase API call to retrieve information about that particular topic. For instance, /m/064t9 corresponds to "Pop Music".
此方法不适用于 YouTube 上 100% 的视频；Metallica 的Whiskey in a Jar" 只返回歌曲和乐队的主题，但是，Britney Spear 的I Want to Go" 正确返回流行音乐"的机器 ID".
Thise method won't work for 100% of videos on YouTube; Metallica's "Whiskey in a Jar" only returns topics for the song and the band, however, Britney Spear's "I Want to Go" correctly returns a machine ID for "Pop Music".
这样做的原因是主题通常是机器生成的，而不是人工策划的(尽管我们会进行质量检查).我们进行了 Google I/O 讨论其工作原理.好消息是，一旦您有了机器 ID，就可以很容易地通过主题 ID 找到其他视频.我们的示例演示了如何执行此操作.
The reason for this is that the Topic is often machine generated, not human curated (though we do quality checks). We did a Google I/O talk about how this works. The good news is that once you DO have a machine ID, it's very easy to find other videos by topic ID. Our samples demonstrate how to do this.
