Using BOSS api with rails - ruby-on-rails

Question

I am trying to use yahoo's BOSS api with rails.
Controller:
class WelcomeController < ApplicationController
def index
require 'bossman'
BOSSMan.application_id = "api key"
boss = BOSSMan::Search.web("prospect park", :count => 5, :filter => "-hate")
puts "Matches:"
puts
boss.results.each { |result| puts "#{result.title} [#{result.url}]" }
end
end
In gem file I have include
gem 'gemcutter'
gem 'bossman','~> 0.4.1'
gem 'fakeweb'
gem 'spec'
gem 'activesupport'
When I run the application, I get the following error:
No such file or directory - getaddrinfo
Extracted source (around line #6):
BOSSMan.application_id = ""
boss = BOSSMan::Search.images("brooklyn dumbo", :dimensions => "large") #Line 6
boss.results.map { |result| result.url }
end

Answer 1

After long hours of debugging I finally managed to get the boss api to work via rails. It's not really polished, but my guess is everybody should be able to work with it.
This is how:
require 'oauth_util.rb'
require 'net/http'
def get_response(buckets, query_params)
parsed_url = URI.parse("https://yboss.yahooapis.com/ysearch/#{buckets}" )
o = OauthUtil.new
o.consumer_key = YAHOO_KEY
o.consumer_secret = YAHOO_SECRET
o.sign(parsed_url,query_params)
Net::HTTP.start( parsed_url.host, parsed_url.port, :use_ssl => true ) { | http |
req = Net::HTTP::Get.new ("/ysearch/#{buckets}?format=json&q=#{query_params}")
req['Authorization'] = o.header
response = http.request(req)
return response.read_body
}
end
Using my altered Verison of oauth_util.rb
# A utility for signing an url using OAuth in a way that's convenient for debugging

require 'uri'
require 'cgi'
require 'openssl'
require 'base64'
class OauthUtil
attr_accessor :consumer_key, :consumer_secret, :token, :token_secret, :req_method,
:sig_method, :oauth_version, :callback_url, :params, :req_url, :base_str
def initialize
#consumer_key = ''
#consumer_secret = ''
#token = ''
#token_secret = ''
#req_method = 'GET'
#sig_method = 'HMAC-SHA1'

#time
end

# ref http://snippets.dzone.com/posts/show/491
def nonce
Array.new( 5 ) { rand(256) }.pack('C*').unpack('H*').first
end
def percent_encode( string )
# ref http://snippets.dzone.com/posts/show/1260
return URI.escape( string, Regexp.new("[^#{URI::PATTERN::UNRESERVED}]") ).gsub('*', '%2A')
end
# #ref http://oauth.net/core/1.0/#rfc.section.9.2
def signature
key = percent_encode( #consumer_secret ) + '&' + percent_encode( #token_secret )

You can try and include Socket lib at the top of your controller.
require 'socket'
this seems like some socket issue with BOSS.
