Hello,

With Twisted and Nevow I'm building an XML-RPC server that does HTTP
authentication. So a basic XML-RPC client can login using
https://user:[EMAIL PROTECTED] I can get the credentials with HTTP
authentication, but how can I check the credentials. I'd tried calling
guard.SessionWrapper.login(....), but I get the error: "exceptions.TypeError:
unbound method login() must be called with SessionWrapper instance as first
argument (got NevowRequest instance instead)".

So I'm guessing that request.getSession() is wrong and I must get the
session of the guard (or something similar). Or I'm calling the wrong
function to check the creds. In the guarded.py example from Nevow the
credentials get checked thru a html form, but that is not what I want.

Below is an example part of my code:

class RootPage(rend.Page):
   ## We are a directory-like resource because we are at the root
   addSlash = True
   ## Doesn't work
   def tryLogin(self, ctx, request):
       session =  request.getSession()
       segments = inevow.ICurrentSegments(ctx)
       httpAuthCredentials = (self.data_username,self.data_password)
       return guard.SessionWrapper.login(request, session,
httpAuthCredentials, segments).addCallback(self._loginSucceeded).addErrback(
self.loginFailed)

   def renderHTTP(self, ctx):
       request = inevow.IRequest(ctx)
       username, password = request.getUser(), request.getPassword()
       ## No REAL authentication yet, must implement it.
       if (username, password) == ('', ''):
           request.setHeader('WWW-Authenticate', 'Basic
realm='+cfg.app_name)
           request.setResponseCode(http.UNAUTHORIZED)
           return "Authentication required."
       ## They provided a username and password, so let's let them in!
horray
       self.data_username, self.data_password = username, password

       self.tryLogin(ctx, request)
       return rend.Page.renderHTTP(self, ctx)

   docFactory = loaders.stan(tags.html[
   tags.body[
       tags.h1["Welcome user!"],
       tags.div["You said: ",
           tags.span(data=tags.directive('username'), render=str),
           " ",
           tags.span(data=tags.directive('password'), render=str),
           tags.a(href=guard.LOGOUT_AVATAR)["Logout"]
           ]]])
