You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: request.rb
    path of file: ./repos/puppet/lib/puppet/indirector
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'cgi'
req
    
  def set_uri_key(key)
    @uri = key
    begin
      # calling uri_encode for UTF-8 characters will % escape them and keep them UTF-8
      uri = URI.parse(Puppet::Util.uri_encode(key))
    rescue => detail
      raise ArgumentError, _("Could not understand URL %{key}: %{detail}") % { key: key, detail: detail }, detail.backtrace
    end
