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。

看起来 ssl 失败了，因为您没有填写参数。试试这样：

require 'open-uri'

app_id = 'fill_me_out'
app_secret = 'fill_me_out_too'
url = "https://graph.facebook.com/oauth/access_token?client_id=#{app_id}&client_secret=#{app_secret}&grant_type=client_credentials"
access_token = open(url).read
