I’ve spent some more time on my current pet, txweb, and I think it’s pretty much at the as good as it gets stage.
Below is the source for the example.py
#App level from txweb import Site, expose #twisted from twisted.web import server, resource from twisted.internet import reactor from twisted.web.static import File from os.path import abspath, dirname, join
Mostly pretty standard imports for a twisted.web application.
Now here is the “Controllers”, they’re stripped down to bare-bones just to keep it simple
class PageOne(object): @expose def foo(self, request): return "Hello From PageOne Foo!" @expose def delayed(self, request): def delayedResponse(): request.write("I was delayed 🙁 ") request.finish() reactor.callLater(5, delayedResponse) return server.NOT_DONE_YET class PageTwo(object): @expose def index(self, request): """ /pagetwo/index """ return "Hello From PageTwo index!" rootFile = lambda filename : abspath(join(dirname(__file__), filename)) class Root(object): @expose def index(self, request): """ Will handle both / and /index paths """ return "Hello From Index!" @expose def __default__(self, request): """ Unless overriden further down, this will catch all 404's """ return "I Caught %s " % request.path pageone = PageOne() pagetwo = PageTwo() readme = File(rootFile("README.md")) license = File(rootFile("txweb/LICENSE.txt"))
Basically a txWeb enabled twisted service converts a URL path to an Object path.
So /hello/world could resolve to root.hello.world() if such a construct was provided.
Much more importantly, with the above example, /license resolves to the local file txweb/LICENSE and /readme resolves to README.md !
In summary txweb doesn’t throw away the epic amount of work the Twisted developers and volunteers have put forth, it just presents it in another way.
