YouTube API: How to get videos from channel X with tag Y?
提问by edt
For example, how could I get a JSON response of all the videos from channel "http://www.youtube.com/nba" that are tagged "playoffs"?
例如，如何从“http://www.youtube.com/nba”频道中获得所有标记为“季后赛”的视频的 JSON 响应？

YouTube calls tagsas categories.
YouTube 调用tags为categories.
The following URL shows videos from NBAchannel with tags playoffsand sports(you can add more obviously) in JSON.
以下 URL以 JSON格式显示来自NBA带有标签playoffs和sports（您可以添加更明显的）频道的视频。

尝试这样的事情：

but this is xml format, look the api document and do it as json by yourself.
但这是xml格式，看api文档，自己做json。
