Ruby-Anfrage https - "in` read_nonblock ': Verbindung von Peer zurückgesetzt (Errno :: ECONNRESET)"

Question

Hier ist mein 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 

und es gibt mir

    from /home/alex/Documents/ruby_test1.rb:20:in `<main>' 

Was ich tat, falsch machen?

Answer 1

Es gibt einige Besonderheiten in Ihrem Code. Das Wichtigste ist: Da Sie SSL verwenden, müssen Sie HTTP.start etwa mit :use_ssl => url.scheme == 'https' bekannt geben. HTTP.Get Konstruktor erwartet für eine URI, nicht den Pfad. Die Zusammenfassung:

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 

Gibt:

#<Net::HTTPOK:0x000000027d0558> 

Answer 2

Accepted Antwort mich gab einen Fehler -

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

Als ich mit -

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

Meine Ruby-Version ist -

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

Dann habe ich geändert, um den Code wie folgt: -

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> 

Und es funktionierte.
