推荐答案

在Facebook上获取任何页面的喜欢都非常容易，尤其是使用Koala宝石时.由于给定页面的Facebook点赞可以公开访问(请参阅此处)，因此您无需访问即可访问它们使用API​​密钥.

It's pretty easy to get the likes of any page on facebook, particularly with the Koala gem. Since the facebook likes for a given page are publically accessible (see here), you can access them without using an API key.

例如，要获得该页面的顶数: facebook.com/foofighters ，您可以这样做:

For example, to obtain the number of likes for this page: facebook.com/foofighters you could do:

graph = Koala::Facebook::GraphAPI.new
likes = graph.get_object("foofighters")["likes"]

我假设您已将用户配置文件存储在应用程序数据库中，并且其中的每个(或某些)都有关联的Facebook ID?如果您要为用户本地保存喜欢"数据，则可以执行以下操作:

I'm assuming you have your user profiles stored in your application database, and each (or some) of these have associated facebook IDs? If you're trying to save the 'like' data locally for your users, you could do something along the lines of:

graph = Koala::Facebook::GraphAPI.new
@users.each do |user|
  user.likes = graph.get_object(user.facebook_id)["likes"]
  user.save
end
