Print Raw HTTP Request and Response Payload in Ruby

http_debug.rb

module Net
  class HTTP
    alias_method(:orig_request, :request) unless method_defined?(:orig_request)

    def request(req, body = nil, &block)
      puts '===== REQUEST ====='
      puts "Request: #{req.method} http://#{@address}:#{@port}#{req.path}"
      puts 'Request headers: '
      req.each_header do |key, value|
        puts "\t#{key}: #{value}"
      end

      if req.method == 'POST'
        data = req.body.nil? || req.body.size == 0 ? body : req.body
        puts "POST Data: #{data}"
      end

      response = orig_request(req, body, &block)
      puts '===== RESPONSE ====='
      puts "Code: #{response.code}"
      puts 'Headers'
      response.each_header do |header, values|
        puts "\t#{header}: #{values.inspect}"
      end
      puts "Body: #{response.body}"

      response
    end
  end
end

I tried and made the response into a raw response.

puts "HTTP/#{response.http_version} #{response.code} #{response.message}"
response.each_capitalized do |header, values|
  puts "#{header}: #{values}"
end
puts
puts response.body
