how can I configure Ruby web client to request web pages using Tor ?
Created a Gem, maybe can help others: https://github.com/brunogh/tor_requests
I think it's like specifying proxy server for your HTTP connection. I don't know how it works in Ruby. But it will not be different from configuring browsers. Just set proxy server setting to 127.0.0.1:8118
.
You just need to work with the Proxy class. As Ivan says above, get Tor running then point Net::HTTP.Proxy at the correct localhost address and you're golden.
I had to use this Gem http://socksify.rubyforge.org/ then I was able to do something like this
TCPSocket::socks_server = "127.0.0.1"
TCPSocket::socks_port = 9050
reply = Net::HTTP.get URI.parse("www.google.com")
Obviously with the Tor proxy running.
