ruby-on-rails - Getting Comments of a URL - Koala Graph API

Question

I wanted to get the list of Facebook comments on a url. For example I have the url "http://example.com/37" Through graph API explorer I only needed this url as the parameter "https://graph.facebook.com/comments/?ids=http:example.com/35." How can I do this using the Koala gem?

Thanks,

Answer 1

为了澄清前面的答案......考拉的文档指出 get_comments_for_urls 方法fetches the comments from fb:comments widgets for a given set of URLs (array or comma-separated string)。因此，当页面上有一个实际的 Facebook 评论框时，此调用有效（此处描述：https ://developers.facebook.com/docs/reference/plugins/comments/ ）。

这是一个带有真实 URL 的工作示例：

oauth            = Koala::Facebook::OAuth.new Facebook::APP_ID, Facebook::SECRET
app_access_token = oauth.get_app_access_token
graph            = Koala::Facebook::API.new app_access_token
urls             = ['http://www.ruhanirabin.com/easy-steps-to-facebook-connect-comment-box-how-to/']
comments         = graph.get_comments_for_urls(urls)

请注意，应用访问令牌与您在 Facebook 开发者网站上的应用配置中指定的应用 ID 和密码不同。

我认为 Koala 并没有让它尽可能直观，因为它需要一个访问令牌——不像直接访问 Graph API。此外，它似乎需要一组 URL。

urls     = ["http://example.com/37"]
graph    = Koala::Facebook::GraphAPI.new(some_access_token)
comments = graph.get_comments_for_urls(urls)
