VinLink

Comments.txt

Depends on the "xml-simple" and "net-http-digest_auth" gems...

For Rails 2:

config/environment.rb:

Rails::Initializer.run do |config|
  ...
  config.gem "xml-simple", :lib => "xmlsimple"
  config.gem "net-http-digest_auth", :lib => "net/http/digest_auth"
  ...
end

vin_link.rb

require "rubygems"
require "uri"
require "net/http"
require "net/http/digest_auth"
require "xmlsimple"

class VinLink

  VINLINK_URL = "http://service.vinlink.com"

  attr_writer :options
  
  #v = VinLink.new(:user => 'foo', :password => 'bar', :report_type => 'basic')
  def initialize(options = {})
    @options = {}
    options.each do |key, value|
      @options[key.to_s] = value.to_s
    end
  end  
  
  #v.decode('1234567890ABCD')
  def decode(vin, report_type = @options["report_type"] )
    url = URI.parse(VINLINK_URL)
    url.user = @options["user"]
    url.password = @options["password"]
    
    http = Net::HTTP.new url.host, url.port
    req = Net::HTTP::Get.new("/report?type=#{report_type}&vin=#{vin}")
    res = http.request req
    digest_auth = Net::HTTP::DigestAuth.new
    auth = digest_auth.auth_header url, res['www-authenticate'], 'GET'
    req.add_field 'Authorization', auth

    @response = http.request(req)

    if @response.code == "200" #yay
      XmlSimple.xml_in(@response.body, 'KeyToSymbol' => true)[:report][0]
    else
      @response.value
    end
  end
end
