[Mongrel] Howto write a mongrel handler for a CGI app using CGIWrapper

[Simon Rozet]

Hello,

Just for further reference in case of someone else want to do the same :

I wanted to write a mongrel for a CGI app :
[[[
require 'cgi'
require 'foo'

cgi = CGI.new

if !cgi['uri'] || (cgi['uri'] == '')
  Foo.error "URI argument is required"
end

uri = cgi['uri']
user = cgi['username']
pass = cgi['password']

foo = Foo.new(:output => 'html')

if user == ''
  foo.check(uri)
else
  foo.check(uri, user, pass)
end
foo.report
]]]

Here is the mongrel version, using Mongrel::CGIWrapper :
[[[
require 'mongrel'
require 'cgi'
require 'foo'

class AppHandler < Mongrel::HttpHandler
  def process(request, response)
    cgi = Mongrel::CGIWrapper.new(request, response)

    if !cgi['uri'] || (cgi['uri'] == '')
      response.start(200, true) do |header, body|

        Foo.error("URI argument is required", output=body)
      end
    end

    format = request.params['HTTP_ACCEPT'] == 'text/plain' ? 'text' : 'html'
    ape = Ape.new({ :crumbs => true, :output => format })

    if cgi['user'] && cgi['pass']
      ape.check(cgi['uri'], cgi['user'], cgi['pass'])
    else
      ape.check(cgi['uri'])
    end

    response.start(200, true) do |head, body|
      ape.report(output=body)
    end
  end
end

h = Mongrel::HttpServer.new('0.0.0.0', 4000)
h.register('/', Mongrel::RedirectHandler.new('/ape/index.html'))
h.register('/ape', Mongrel::DirHandler.new(File.dirname(__FILE__) +
'/layout', true))
h.register('/atompub/go', ApeHandler.new)
h.run.join
]]]
