accessing a website through a proxy using Net::HTTP proxy in ruby

问题

I'm trying to access a QA environment website using Net::HTTP::Proxy to get the response.But I keep getting a SocketError whenever I try to connect. Please find the code snippet that I'm trying to use.

proxy_addr = "http://autoproxy1.qa.com"
proxy_class = Net::HTTP::Proxy(proxy_addr,80).start("mywebsite.com")

This is the Error I'm getting

SocketError: getaddrinfo: Name or service not known

I'm able to access the same website using Selenium by configuring the autoproxy settings of the browser. But I need to get the response of it through Net::HTTP. Please let me know if there is any other way of doing it.

回答1:

try removing the http:// from your proxy address.

回答2:

#!/usr/bin/ruby1.9.3 
require 'net/http'

proxy_addr = '109.104.128.130'
proxy_port = 8741

Net::HTTP::Proxy(proxy_addr, proxy_port).start('www.templesec.org') {|http|}

回答3:

Net::HTTP accepts URI's for the start and get classes, so you could change your code to something like this:

require 'uri'
require 'net/http'
proxy_addr = "http://autoproxy1.qa.com"
proxy_port = 80
proxy_class = Net::HTTP::Proxy(proxy_addr, proxy_port).start(URI("mywebsite.com"))
