cookies code

Persistent Rails cookie session

Session cookies, the Rails-2 kind, are transient because that's safer. In some applications safety isn't important. The following makes the session cookies persist for a year.

class ApplicationController < ActionController::Base
  before_filter :update_session_expiration_date

private
  def update_session_expiration_date
    unless ActionController::Base.session_options[:session_expires]
      ActionController::Base.session_options[:session_expires] = 1.year.from_now
    end
  end
end

Getting Started With WWW::Mechanize

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.

output (extract):

=> #<WWW::Mechanize::Page
 {url #<URI::HTTP:0xfdbbbb286 URL:http://www.google.com/>}
 {meta}
 {title "Google"}
 {iframes}
 {frames}
 {links
  #<WWW::Mechanize::Page::Link
   "Images"
   "http://images.google.com/imghp?hl=en&tab=wi">
  #<WWW::Mechanize::Page::Link
   "Maps"
   "http://maps.google.com/maps?hl=en&tab=wl">

Integrating reinvigorate name tags into a PHP site

This is a script which will intergrate reinvigorate name tags into your PHP site using cookies
Put this on any page you want to have visitors enter their name

<FORM ACTION="index.php" METHOD="GET">
<p>Name <INPUT TYPE=TEXT NAME= "n" SIZE=20><br>
<INPUT TYPE=SUBMIT VALUE="Submit!">

Put this on your index.php page at the top before anything. This will set a cookie that will last for 2 months

<?php
$Name = $_GET['n'];
?>
<?php
$inTwoMonths = 60 * 60 * 24 * 60 + time(); 
setcookie('name', $Name, $inTwoMonths); 
?>

Put this at the first line after the <body> tag. You need to change the USER-ID to your user ID that
you can get from the regular reinvigorate code.

<script type="text/javascript" src="http://include.reinvigorate.net/re_.js"></script>
<script type="text/javascript">
var re_name_tag = "<?php echo $Name; ?>";
re_("USER-ID");
</script>

Custom HTTP/HTTPS GET/POST queries in Ruby

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
