Interacting with 3rd party services

Lightning talk at RuLu 2014

1. Interacting with 3rd party web services Keep it simple and lightweight RuLu 2014, June 19-20
2. Request • query parameters • JSON or XML body • SOAP envelope
3. Response • JSON or XML body • SOAP envelope
4. Mapping to Ruby objects • JSON to Hash : easy • XML to Nokogiri : doable • SOAP to anything : attrocious
5. Too big? Inadequate?
6. Custom mapping with ROXML
7. require 'roxml' module Mapping class Base include ROXML xml_convention :capitalize end class Room < Base xml_reader :total_price, :from => '@TotalPrice', :as => Float xml_reader :nb_rooms, :from => '@NbRooms', :as => Integer def breakfast_included? %w(B D P A).include?(meals.to_s) end end class Hotel < Base xml_reader :native_id, :from => "@DistNum" xml_reader :name, :from => "@Name" xml_reader :rooms, :as => [Room] end class FB_MultirateRS < Base xml_reader :hotels, :as => [Hotel], :from => 'Hotels/Hotel' end end
8. Simplify
9. JSON Request free with Ruby Hash
10. XML Request • raw String • ERB templates • XML builders
11. Response • Mappers • Models
12. Thank You with a special to Fabien Catteau
