Posting to other website's form and getting response with Rails

I am trying to send some params to this website (http://www.degraeve.com/translator.php) and get the response to my rails application. I want to select 'binary' from the radio buttons whose name is 'd' and put just 'a' on the text field whose name is 'w' to be translated. I am using this action on my controller:

class RoomsController < ApplicationController
  require "uri"
  require "net/http"
  require 'json'


  def test    

    uri = URI.parse("http://www.degraeve.com/translator.php")
    header = {'Content-Type': 'text/json'}
    params = { d: 'binary', w: 'a' }

    # Create the HTTP objects
    http = Net::HTTP.new(uri.host, uri.port)
    request = Net::HTTP::Post.new(uri.request_uri, header)
    request.body = params.to_json

    # Send the request
    response = http.request(request)
    render json: response.body
  end
end

Is there something wrong? It just renders the body of http://www.degraeve.com/translator.php before submitting the form, but I would like to get the body after it has been submitted.

When you look at what happens after you press the "Translate!" button you may notice that there is no form being submitted via POST. Instead, a GET request is sent and a HTML file is returned - see for yourself in your browser's network inspector.

Consequently, you can send a simple GET request with a prepared URL, like this (note the d and w query parameters):

uri = URI.parse("http://www.degraeve.com/cgi-bin/babel.cgi?d=binary&url=http%3A%2F%2Fwww.multivax.com%2Flast_question.html&w=a")
response = Net::HTTP.get_print(uri)

and then parse the response accordingly.
