Like I mentioned in my previous post about saving cookies with cURL in this post I’m going to show you how to do it with ruby.

I found this stackoverflow answer that talks about using http-cookie which doesn’t look like it has been updated in over 3 years, but it did work just fine.

I created the golds_checkin repo to store the ruby code of this project. Currently it is just an app.rb file, but I will most likely turn it into an actual ruby gem.

Here is the output of my app.rb file:

require 'yaml'
require 'net/http'
require 'http-cookie'
require 'cgi'

class GoldsCheckin
  def initialize
    @config = YAML.load_file('config.yml')
    @jar =

  def login
    uri = URI('')

    Net::HTTP.start(, uri.port, use_ssl: true) do |http|
      req = uri
      req.form_data = { "j_username": @config['username'], "j_password": @config['password'] }
      res = http.request req
      res.get_fields('Set-Cookie').each do |value|
        @jar.parse(value, req.uri)

  def fetch_checkins
    low_date = CGI::escape("%m/%d/%Y"))
    high_date = CGI::escape("%m/%d/%Y"))
    uri = URI("{low_date}&highDate=#{high_date}")

    Net::HTTP.start(, uri.port, use_ssl: true) do |http|
      req =
      req['Cookie'] = HTTP::Cookie.cookie_value(@jar.cookies(uri))
      res = http.request req


golds_checkin =

puts golds_checkin.fetch_checkins

Basically there are two methods, ‘login’ and ‘fetch_checkins’. ‘login’ reads my credentials out of a yaml file and makes a POST request wich then sets the returned cookies into the @jar instance variable so that we can use it for subsequent requests. Once we are logged in then we can call ‘fetch_checkins’ which I have set to only fetch today’s date. This call reads from the cookie jar in order to make an authenticated request.

From these two posts (this one and yesterdays) you can start to see my process for making an app. I usually start with just playing around on the command line. Then I translate all of that knowledge into a simple app.rb file. From there I think it kind of depends what my end goal is, but then the app.rb file evolves in some way where it no longer just lives on my local computer, but gets turned into a ruby gem to be used in another project, or it evovles into a larger web application.
