basic authentication

[depaolim]

support fo basic authentication via decorator

Implementation proposal:

import base64

from django.http import HttpResponse
from django.contrib.auth import authenticate, login


def basicauth_required(realm=""):
    "Based on http://djangosnippets.org/snippets/243/"

    def external_wrapper(view):
        def wrapper(request, *args, **kwargs):
            if 'HTTP_AUTHORIZATION' in request.META:
                auth = request.META['HTTP_AUTHORIZATION'].split()               
                if len(auth) == 2:
                    if auth[0].lower() == "basic":
                        uname, passwd = base64.b64decode(auth[1]).split(':')
                        user = authenticate(username=uname, password=passwd)
                        if user is not None:
                            if user.is_active:
                                login(request, user)
                                request.user = user
                                return view(request, *args, **kwargs)

            # the authorization attempt failed. Send a 401
            # back to them to ask them to authenticate.
            #
            response = HttpResponse()
            response.status_code = 401
            response['WWW-Authenticate'] = 'Basic realm="%s"' % realm
            return response
        return wrapper
    return external_wrapper
