Accessing a feed using ClientLogin & Ruby

Example of accessing the DocList API using ClientLogin in Ruby:

require 'net/http'
require 'net/https'
require 'cgi'
require 'rubygems'
require 'xmlsimple'
require 'pp'

def get_feed(uri, headers=nil)
  uri = URI.parse(uri)
  Net::HTTP.start(uri.host, uri.port) do |http|
    return http.get(uri.path, headers)
  end
end

email = 'user@gmail.com'
password = CGI::escape('pa$$word')
service = 'writely'
source = 'MyCompany-MyApp-0.1'
path = '/accounts/ClientLogin'

data = ["accountType=HOSTED_OR_GOOGLE", 
        "Email=#{email}",
        "Passwd=#{password}",
        "service=#{service}",
        "source=#{source}"].join('&')

http = Net::HTTP.new(host='www.google.com', port=443)
http.use_ssl = true
http.start

headers = {'Content-Type' => 'application/x-www-form-urlencoded'}
resp, data = http.post(path, data, headers)

token = data[/Auth=(.*)/, 1]  # parse out the Auth token

headers['Authorization'] = "GoogleLogin auth=#{token}"
resp = get_feed('http://docs.google.com/feeds/documents/private/full', headers)

doc = XmlSimple.xml_in(resp.body, 'KeyAttr' => 'name')
pp doc
