Getting Started With WWW::Mechanize

jrobertson (James Robertson) — Tue, 12 Feb 2008 17:53:54 GMT

This Ruby code uses WWW:mechanize to act like a web browser.



 require 'rubygems'

 require 'mechanize'



 agent = WWW::Mechanize.new

 page = agent.get('http://google.com/')

Refer to the documentation at http://mechanize.rubyforge.org/mechanize/. Then gem install mechanize, and try running the code in an irb session.

Need a simple way to make sure all http requests get redirected to https?
This apache config snippet will redirect all requests at or below the specified location to its https equivilant.

Custom HTTP/HTTPS GET/POST queries in Ruby

paulgoscicki (Paul Goscicki) — Thu, 06 Oct 2005 03:50:12 GMT

First, the scripts sends the GET query to read the website cookies (for session, etc.), and then it sends a POST query with the received cookies and custom POST parameters.



require 'net/http'

require 'net/https'



http = Net::HTTP.new('profil.wp.pl', 443)

http.use_ssl = true

path = '/login.html'



# GET request -> so the host can set his cookies

resp, data = http.get(path, nil)

cookie = resp.response['set-cookie']





# POST request -> logging in

data = 'serwis=wp.pl&url=profil.html&tryLogin=1&countTest=1&logowaniessl=1&login_username=blah&login_password=blah'

headers = {

  'Cookie' => cookie,

  'Referer' => 'http://profil.wp.pl/login.html',

  'Content-Type' => 'application/x-www-form-urlencoded'

}



resp, data = http.post(path, data, headers)





# Output on the screen -> we should get either a 302 redirect (after a successful login) or an error page

puts 'Code = ' + resp.code

puts 'Message = ' + resp.message

resp.each {|key, val| puts key + ' = ' + val}

puts data
