Requête Ruby à https - "in` read_nonblock ': Connexion réinitialisée par homologue (Errno :: ECONNRESET) "

Voici mon code

domain = 'http://www.google.com'
url = URI.parse "https://graph.facebook.com/fql?q=SELECT%20url,normalized_url%20FROM%20link_stat%20WHERE%20url='#{domain}'"
req = Net::HTTP::Get.new url.path
res = Net::HTTP.start(url.host, url.port) {|http| http.request req}
puts res.body

et il me donne

    Il y a plusieurs bizarreries dans votre code. La principale est: puisque vous utilisez SSL vous êtes à la connaissance HTTP.start avec :use_ssl => url.scheme == 'https'. HTTP.Get constructeur attend pour un URIet non pas le chemin. Le résumé:

    domain = 'http://www.google.com'
url = URI.parse("https://graph.facebook.com/fql?q=SELECT%20url,normalized_url%20FROM%20link_stat%20WHERE%20url='#{domain}'")
req = Net::HTTP::Get.new url 
res = Net::HTTP.start(url.host, url.port, 
        :use_ssl => url.scheme == 'https') {|http| http.request req}
puts res

    Donne:

    #<Net::HTTPOK:0x000000027d0558>

    Accepté réponse a été de me donner une erreur -

    `initialize': no implicit conversion of Hash into String (TypeError)

    Quand j'étais aide -

    Net::HTTP.start(url.host, url.port, :use_ssl => url.scheme == 'https')

    Ma version de Ruby est -

    arup_ruby$ ruby -v
ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-darwin12.0]

    Ensuite, j'ai modifié le code comme ci-dessous :-

    require "uri"
require "net/http"

domain = 'http://www.google.com'
uri = URI.parse("https://graph.facebook.com/fql?q=SELECT%20url,normalized_url%20FROM%20link_stat%20WHERE%20url='#{domain}'")
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true if uri.scheme == 'https'
req = Net::HTTP::Get.new uri
res = http.start { |http| http.request req }
puts res
# >> #<Net::HTTPOK:0x000001018f8520>

    Et cela a fonctionné.
