用户在Django中的哪个位置成为AnonymousUser？

Question

I'm trying find out where/when exactly request.user becomes an AnonymousUser. I've been searching through the entire Auth backend but I can't seem find it. Am I looking in the wrong place?

I'm aware that every user that isn't an Authenticated user becomes an AnonymousUser, but I need to know where/when this happens for some code I'm building.

Any help would be appreciated.

Answer 1

contrib\\auth\\__init__.py:80

def get_user(request):
    from django.contrib.auth.models import AnonymousUser
    try:
        user_id = request.session[SESSION_KEY]
        backend_path = request.session[BACKEND_SESSION_KEY]
        backend = load_backend(backend_path)
        user = backend.get_user(user_id) or AnonymousUser()
    except KeyError:
        user = AnonymousUser()
    return user

一切都在django.contrib.auth.middleware模块中-有关详细信息，请参见： https : //github.com/django/django/blob/master/django/contrib/auth/middleware.py#L49 。

Answer 3

logout method in "contrib/auth/ init .py" also affect AnonymousUser() to request.user, look at the code below:

if hasattr(request, 'user'):
    from django.contrib.auth.models import AnonymousUser
    request.user = AnonymousUser()
