node.js http serverで複数のremoteHost, requestMethodを判定してアクセス制御をする

node-access-limitter.coffee

http = require 'http'

allows =
	"127.0.0.1" : ['POST','PUT']
	"192.168.0.10" : ['GET','POST','PUT','DELETE']

httpServer = http.createServer (req, res)->
	allowed = false
	for ip, methods of allows
		if ip == req.connection.remoteAddress
			allowed = true
		else
			allowed = false
		if allowed
			unless methods.indexOf(req.method) == -1
				allowed = true
				break
			else
				allowed = false
	if allowed
		res.writeHead 200, {'Content-Type':'text/plain'}
		res.end 'access allowed'
	else
		res.writeHead 403, {'Content-Type':'text/plain'}
		res.end 'access forbidden'
httpServer.listen 3000
