What is in newrest.rb?

def retrieve
url = “http://localhost:3000/branches/
resource = RestClient::Resource.new url+$param[“id”]
puts resource
end

ruby newrest.rb id=“22”

                      newrest.rb

require ‘rubygems’

require ‘rest_client’

require ‘json’

$param = Hash.new

def retrieve

  • url = “http://localhost:3000/branches”*

  • resource = RestClient::Resource.new url +"/"+$param[“id”]*

  • puts resource*

  • begin*

  •    response = resource.get :content_type => :json, :accept => 
    

:json*

  •    case response.code*
    
  •    when 200*
    
  •        puts response.to_s*
    
  •    end*
    
  • rescue => e*

  • puts e*

  • end*

*end *

Here just i pass the ID through command line ie ruby newrest.rb
id=“22”.
so what i need is , the above code have this

url = “http://localhost:3000/branches

  • resource = RestClient::Resource.new url +"/"+$param[“id”]*

i have to read that id value, which coming via the command line, and
append that value with this URL http://localhost:3000/branches/22

So* ** resource = RestClient::Resource.new url +"/"+$param[“id”] *this
is
the correct to get that value? or any way to get the value and append?

I don’t see in the code where the method retrieve is called, so I
would not expect ruby newrest.rb to do anything.
Also I don’t see how the command line value id is being loaded into
$param. Normally for ruby command line args I use ARGV or
OptionParser. Google for ruby command line parameters and you will
find how to do it.
