您应该使用“global”值，它是不同后端中可用内容的副本，除非您希望为特定格式/平台提供信息。
要在代码中使用它，可以执行以下操作：
from embeder import embed
data = embed.get('http://www.youtube.com/watch?v=-r3VuOyr9lk')
后端
- 默认后端检索页面的标题和描述元标记
- oembed后端检索一些oembed信息：http://oembed.com/
- opengraph后端检索一些opengraph元标记：http://ogp.me/
- twitter后端检索一些twitter元标记：https://dev.twitter.com/docs/cards/markup-reference
