HTTParty

XML

JSON

HTTParty HASH

Installation

sudo gem install httparty

Ein erstes Beispielrequire "rubygems"require "httparty"

response = HTTParty.get('http://twitter.com/statuses/public_timeline.json')

# puts response.body# puts response.code # => 200# puts response.message # => OK# puts response.headers.inspect

response.each do |item| puts item['user']['screen_name']end

# => alexmedeiros59# => EmySayers# => ciquuuee# => bray1972# => shasoGORGEOUS# => kimix

Beispiel Twitter-APIclass Twitter include HTTParty base_uri 'twitter.com' def initialize(u, p) @auth = {:username => u, :password => p} end def timeline(which=:friends, options={}) options.merge!({:basic_auth => @auth}) self.class.get("/statuses/#{which}_timeline.json", options) end def post(text) options = { :query => {:status => text}, :basic_auth => @auth } self.class.post('/statuses/update.json', options) endend

twitter = Twitter.new(USERNAME, PASSWORD)pp twitter.timeline.map{|t| t['user']['name']}
