Question

我正在尝试使用ruby下载https://fbcdn-profile-a.akamaihd.net/hprofile-ak-snc4/174043_1701680_6450592_q.jpg，但是出现连接重置错误。它可以在浏览器中下载，但不能在Ruby中下载。这是Ruby中的错误吗？ Facebook的一个错误？

这适用于大多数其他Facebook用户。我使用的是Ruby 1.8.7和rails 2.3.11。

>> http = Net::HTTP.new("graph.facebook.com", Net::HTTP.https_default_port)
=> #<Net::HTTP graph.facebook.com:443 open=false>
>> http.use_ssl = true
=> true
>> http.start do |http|
?> response = Net::HTTP.get_response(URI.parse('https://fbcdn-profile-a.akamaihd.net/hprofile-ak-snc4/174043_1701680_6450592_q.jpg'))
>> end

这是一个稍微修改过的版本......

require 'uri'
require 'net/https'

url = URI.parse 'https://fbcdn-profile-a.akamaihd.net/hprofile-ak-snc4/174043_1701680_6450592_q.jpg'
http = Net::HTTP.new url.host, url.port
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
http.use_ssl = true

http.start do |agent|
  p agent.get(url.path).read_body.length
end

然后......

    so ross$ ruby fbi

Ruby Net：HTTP SSL错误还是我？
