我一直在尝试使用 facebook graph api,虽然 ruby 在打开 api url (https://graph.facebook.com/.....) 时会引发 EOFError 我使用的是 Ruby 1.8.6 和 Rails 2.2.2。代码如下:
require 'uri'
require 'https'
access_token = open("https://graph.facebook.com/oauth/access_token?client_id=app_id&client_secret=app_secret&grant_type=client_credentials"){|f|
f.read
}
出现以下错误:

我彻底谷歌并搜索了这个错误,并尝试了 httpparty、机制、fb_graph 和 koala。但是,那些会引发相同的 efoerror。ruby-1.8.6 或者 open-uri 好像有bug,但是我不想升级ruby。
有任何想法吗?提前致谢。
