Con el lanzamiento de Yahoo! BOSS ha llegado BOSSMan, un plugin/gem creado por el desarrollador Jay Pignata que permite interactuar con éste nuevo API de Yahoo! de una forma bien simple, como son las cosas en Ruby.
Para ver como funciona he creado un buscador de noticias bilingüe utilizando Ruby on Rails, http://yahoosearch.heroku.com. Aquí está el código:
Instalación de BOSSMan:
gem sources -a http://gems.github.com
gem install jpignata-bossman
controllers/search_controller.rb
require 'rubygems'
require 'bossman'
include BOSSMan
class SearchController < ApplicationController
def index
@results = Array.new
@language = [true, false]
if (request.post? and params[:query] != "")
BOSSMan.application_id = "<Your Application ID>"
@news = BOSSMan::Search.news(params[:query], {
:region => 'us',
:lang => params[:language],
:age => "7d",
:count => 10 })
@results = @news.results if @news.count != "0"
@language = [false, true] if params[:language] == 'es'
end
end
end
