Subject: Re: easy access for CGI query

Hello, again.

require "cgi"
ENV['REQUEST_METHOD'] = 'GET'
ENV['QUERY_STRING'] =
  'key=value1&key%20with%20spaces=value2&key%2fwith%2fslashes=value3'
class CGI
  class Query
    def initialize(params, substitute)
      @params = params
      @substitute = substitute
    end
    def method_missing(key)
      @params[@substitute[key] || key.to_s].first
    end
  end
  def query(substitute = {})
    CGI::Query.new(@params, substitute)
  end
end


q = CGI.new.query
p q.key               # ==> "value1"
p q.key_with_spaces   # ==> nil
p q.key_with_slashes  # ==> nil


q = CGI.new.query(
      :ruby_name        => "cgi name",
      :key_with_spaces  => "key with spaces",
      :key_with_slashes => "key/with/slashes"
    )
p q.key               # ==> "value1"
p q.key_with_spaces   # ==> "value2"
p q.key_with_slashes  # ==> "value3"
