AxesBackend 需要请求作为参数进行身份验证

Question

我需要对我的 django 站点的帐户登录尝试添加限制，我找到了流行的 django-axes 库，遵循文档和代码示例，但是当我尝试登录我的帐户时（密码是否正确）或没有）我收到错误 AxesBackend 需要一个请求作为参数进行身份验证，即使我的代码完全遵循说明并且我正在传递请求。 以下是与此相关的所有代码：

设置.py

INSTALLED_APPS = [
    ...
    'axes',
]

MIDDLEWARE = [
    ...
    'axes.middleware.AxesMiddleware',
]

AXES_FAILURE_LIMIT =  4
AXES_RESET_ON_SUCCESS = True
AXES_COOLOFF_TIME = 1

AUTHENTICATION_BACKENDS = [
   'axes.backends.AxesBackend', # Axes must be first
   'django.contrib.auth.backends.ModelBackend',
]

AUTH_USER_MODEL = "users.User"
LOGIN_URL = "/user/login/"

views.py

from django.contrib import auth, messages

def login(request):

    if request.method == "POST":
        form = UserLoginForm(data=request.POST)
        if form.is_valid():
            username = request.POST["username"]
            password = request.POST["password"]
            user = auth.authenticate(request=request, username=username, password=password)

            if user:
                auth.login(request, user)

                redirect_page = request.POST.get("next", None)

                if redirect_page and redirect_page != reverse("user:logout"):
                    return HttpResponseRedirect(request.POST.get("next"))

                return HttpResponseRedirect(reverse("main:main_page"))
    else:

        form = UserLoginForm()

    context = {"title": "Вход", "form": form}

    return render(request, "users/login.html", context)

forms.py

from django import forms
from django.contrib.auth.forms import (
    AuthenticationForm,
    UserCreationForm,
    UserChangeForm,
)
from users.models import User


class UserLoginForm(AuthenticationForm):

    username = forms.CharField()
    password = forms.CharField()

    class Meta:
        model = User
        fields = ["username", "password"]

版本库

Django==5.0.4
django-axes==6.5.2

我将非常感谢您的帮助！

Answer 1

它失败的原因是因为你的

UserLoginForm

已经尝试了

authenticate()

，而失败是因为它没有

request

对象。

好消息是：我们可以让表单处理和请求，例如：

from django.urls import redirect


def login(request):
    if request.method == 'POST':
        form = UserLoginForm(request=request, data=request.POST)
        if form.is_valid():
            user = form.get_user()
            if user:
                auth.login(request, user)
                redirect_page = request.POST.get('next', None)

                if redirect_page and redirect_page != reverse('user:logout'):
                    return HttpResponseRedirect(request.POST.get('next'))
                return redirect('main:main_page')
    else:
        form = UserLoginForm()
    context = {'title': 'Вход', 'form': form}
    return render(request, 'users/login.html', context)
