想要使用装饰器保护视图功能免受匿名用户的攻击

Question

我有django网站，需要身份验证和用户登录才能使用某些功能和查看模板。

我使用装饰器 @login_required ，但没有任何变化，任何人仍然可以查看html页面并使用任何功能。

我的代码中缺少什么？

views.py

from django.contrib.auth.decorators import login_required
# Create your views here.

@login_required(login_url="/login/")
def create(request):
...
   return render(request,'blog/create.html')

urls.py

"""ABdatabase URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/2.2/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))

from django.contrib import admin

即使在我使用装饰器之后，它也没有改变。

尝试

def create(request):
    user = request.user
    if not user.is_authenticated:
        return redirect('/')    # Redirect whatever you want
