Question

a fews days ago, i tried to learn the python twisted..
and this is how i make my webserver :

from twisted.application import internet, service
from twisted.web import static, server, script
from twisted.web.resource import Resource
import os

class NotFound(Resource):
    isLeaf=True
    def render(self, request):
        return "Sorry... the page you're requesting is not found / forbidden"

class myStaticFile(static.File):
    def directoryListing(self):
        return self.childNotFound

#root=static.file(os.getcwd()+"/www")
root=myStaticFile(os.getcwd()+"/www")
root.indexNames=['index.py']
root.ignoreExt(".py")
root.processors = {'.py': script.ResourceScript}
root.childNotFound=NotFound()
application = service.Application('web')
sc = service.IServiceCollection(application) 
i = internet.TCPServer(8080, server.Site(root))#@UndefinedVariable
i.setServiceParent(sc)

in my code, i make an instance class for twisted.web.static.File and override the directoryListing.
so when user try to access my resource folder (http://localhost:8080/resource/ or http://localhost:8080/resource/css), it will return a notFound page.
but he can still open/read the http://localhost:8080/resource/css/style.css.
it works…

what i want to know is.. is this the correct way to do that???
is there another ‘perfect’ way ?
i was looking for a config that disable directoryListing like root.dirListing=False. but no luck…

Yes, that’s a reasonable way to do it. You can also use twisted.web.resource.NoResource or twisted.web.resource.Forbidden instead of defining your own NotFound.
