Django Middleware无法正确处理视图函数

Question

我正在尝试使用Django中间件进行登录/注销。我已经看过很少的教程，但所有教程都是旧版本发布的。我试图对中间件中的except函数进行硬编码，而不是按照如下方式在setting.py中进行编码：

middleware.py：

EXEMPT_FUNC = ['Accounts:login', 'Accounts:logout', 'Accounts:register']

class LoginRequiredMiddleware:

    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        response = self.get_response(request)
        return response

    def process_view(self, request, view_func, view_args, view_kwargs):
        assert hasattr(request, 'user')
        path = request.path_info.lstrip('/')
        url_is_exempt = any(url.match(path) for url in EXEMPT_FUNC)

        if path == reverse('Accounts:logout').lstrip('/'):
            logout(request)

        if request.user.is_authenticated() and url_is_exempt:
            return redirect('User:home')
        elif request.user.is_authenticated() or url_is_exempt:
            return None
        else:
            return redirect('Accounts:login')

url.py：

app_name = 'Accounts'
urlpatterns = [
    path('login', views.login_view, name='login'),
    path('logout', views.logout_view, name='logout'),
    path('register', views.register_view, name='register')
]

以上代码未按预期工作，请帮助我做错什么。

非常感谢您的帮助。

最后是它的工作。这是我更改的内容。

middleware.py：

import re

from django.conf import settings
from django.urls import reverse
from django.shortcuts import redirect
from django.contrib.auth import logout

from Accounts import views

#if hasattr(settings, 'LOGIN_EXEMPT_URLS'):
#    EXEMPT_URLS += [re.compile(url) for url in settings.LOGIN_EXEMPT_URLS]

EXEMPT_PATH = ['login', 'logout', 'register']

class LoginRequiredMiddleware:

    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        response = self.get_response(request)
        return response

    def process_view(self, request, view_func, view_args, view_kwargs):
        assert hasattr(request, 'user')
        path = request.path_info.lstrip('/')
        exempt = False

        if path in EXEMPT_PATH:
            exempt = True
            #if path == reverse('Accounts:logout').lstrip('/'):

        if path == 'logout':
            logout(request)

        if request.user.is_authenticated and exempt:
            return redirect('User:home')
        elif request.user.is_authenticated or exempt:
            return None
        else: 
            return redirect('Accounts:login')

使用这种方法，我不需要修改settings.py。

我希望这会有所帮助。
