Micro-Server to validate oAuth2 roles :)

server.rb

# How to use:
#
# $ruby server.rb
# $curl --header "X-Company-Roles: manager" --header "X-Company-Roles: admin" http://localhost:2345/

require 'socket'
require 'json'

server = TCPServer.new('localhost', 2345)

loop do
  socket = server.accept

  request = socket.gets

  #STDERR.puts request

  response = {:roles => []}

  roles = []

  while line = socket.gets
    matches = /^X-([a-zA-Z]+)-Roles\: ([a-z]+)$/.match(line.chomp)
    if matches
      response[:roles] << matches.captures[1]
    end
    break if line =~ /^\s*$/
  end

  socket.print "HTTP/1.1 200 OK\r\n" +
               "Content-Type: application/json\r\n" +
               "Content-Length: #{response.to_json.bytesize}\r\n" +
               "Connection: close\r\n"
  socket.print "\r\n"
  socket.print response.to_json
  socket.close
end
