curl --max-time 15 --silent http://localhost:3000/products/2/who_bought.xml

Enable basic auth

edit app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
  before_action :authorize
 
    # ...
 
  protected
 
    def authorize
      if request.format == Mime[:html]
        unless User.find_by(id: session[:user_id])
          redirect_to login_url, notice: "Please log in"
        end
      else
        authenticate_or_request_with_http_basic do |username, password|
          user = User.find_by(name: username)
          user && user.authenticate(password)
        end
      end
    end
