#

require 'fakeweb'
require 'open-uri'
require 'fileutils'
module FakeWeb
  class << self
    def register(method,uri,klass)
      file_path = File.join(File.dirname(__FILE__),to_s,"#{klass.to_s}.#{uri.hash}.fakeweb")
      content = nil
      unless File.exists?(file_path)
        FileUtils.mkdir_p(File.dirname(file_path))
        content = open(uri).read
        File.open(file_path,File::CREAT|File::TRUNC|File::RDWR) do |f|
          f << content
        end
      else
        content = File.open(file_path).readlines.join 
      end
      self.register_uri(method,uri,:body => content)
    end
  end
