Question

benim kod

domain = 'http://www.google.com' 
url = URI.parse "https://graph.facebook.com/fql?q=SELECT%20url,normalized_url%20FROM%20link_stat%20WHERE%20url='#{domain}'"

res = Net::HTTP.start(url.host, url.port) {|http| http.request req} 
puts res.body

verir yanlış yap?

Answer 1

Kodunuzda birçok tuhaflık vardır. Ana şudur: SSL'u kullandığınızdan, 'u :use_ssl => url.scheme == 'https' numaralı telefondan edinebilirsiniz. HTTP.Get yapıcı, yolu değil URI'u bekliyor. özetliyor:

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 

verir:

#<Net::HTTPOK:0x000000027d0558> 

Answer 2

Accepted cevap bana bir hata veriyordu -

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

ben kullanıyordum -

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

My Yakut sürümü -

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

Sonra ben aşağıdaki kodu modifiye: -

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> 

Ve işe yaradı.
