#!/usr/bin/env ruby

require 'webrick'

document_root = './'
rubybin = '~/.rbenv/shims/ruby'

server = WEBrick::HTTPServer.new({
  DocumentRoot: document_root,
  BindAddress: '0.0.0.0',
  CGIInterpreter: rubybin,

})


['INT', 'TERM'].each {|signal|
  Signal.trap(signal){ server.shutdown }
}

server.start

階上を計算するCGI¶

#!/usr/bin/env ruby

require 'cgi'

def fact(n)
  n == 0 ? 1 : n * fact(n - 1)
end

cgi = CGI.new
n = cgi['n'].to_i
print cgi.header
puts ""
puts ""
puts "#{n} ! = #{fact(n)}"
puts ""
