Trying to get list of freinds from twitter using httparty(ruby)

I am trying to get the list of specific user`s friends from twitter. This is my code -

require 'rubygems'
require 'httparty'

class TwitterData
  include HTTParty
  base_uri ''
  default_params :output => 'json'
  format :json

  def self.get_username_data(username)
    get('statuses/friends.json' , :query => { :screen_name => username })

puts "Please your twitter username - "
twitter_username = gets
puts TwitterData.get_username_data(twitter_username).inspect

This is the error I am getting -

Please your twitter username -

I am new to ruby,So I am sorry if this is a newbie question. Thanks , Yosy.


Replace your method with this

def self.get_username_data(username)


def self.get_username_data(username)
  get('/statuses/friends.json' , :query => { :screen_name => username.strip })

You need to strip the username because from command line when user enters the twitter username and hits enter key a "\n" gets appended to the username and the same username is sent as a parameter which causes the problem. Any of the above given code snippets should work.
