Django-注销后单击浏览器后退按钮以重新进入用户会话

我尝试了此解决方案,它对我有用。我把@cache_control(no_cache = True,must_revalidate = True,no_store = True)和@login_required都放在下面的代码中。



记住要导入现金控制。 / p>

如果我不选择其中之一,它将不起作用。他们一起工作。只需看下面的代码

 从django.contrib.auth.decorators导入login_required 
从django.views.decorators中。缓存导入cache_control
@cache_control(no_cache = True,must_revalidate = True,no_store = True)
@login_required(login_url ='login')
def myview(request):
返回HttpResponse(render(request,'path_to_your_view.html'))

我正在使用django 2.1并删除了'/ login /'中的斜杠并改用'login'


I am creating a web application on Django. When a logged-in user clicks 'Logout', the logout page correctly appears. However, when clicking the back button in the browser, the user can once more re-enter the session. To fix this, I followed this post : Disable browser 'Back' button after logout? , and used cache_control. However, the user can still re-enter the 'closed' session by clicking the back button. Here's the relevant code:

views.py:

from django.views.decorators.cache import cache_control

@cache_control(no_cache=True, must_revalidate=True, no_store=True)
def logout_view(request):

#c={}
#c.update(csrf(request))
logout(request)
#request.session.flush()
#request.user = AnonymousUser
#Redirect to logout page
return render_to_response('gamestore/logout.html')

@cache_control(no_cache=True, must_revalidate=True, no_store=True)
def login_view(request):

    #do something

settings.py:

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
import os
BASE_DIR = os.path.dirname(os.path.dirname(__file__))
SETTINGS_PATH = os.path.realpath(os.path.dirname(__file__))
DATABASE_PATH = os.path.join(BASE_DIR, 'db.sqlite3')

TEMPLATE_DIRS = (
# Put strings here, like "/home/html/django_templates" or "C:/www/django/templates".
# Always use forward slashes, even on Windows.
# Don't forget to use absolute paths, not relative paths.
#"/home/mukhera3/Desktop/wsdProject/gamestore/templates", #TODO use absolute path here

)

I am new to Django and Python coding, so may have made some basic errors. Please help

I tried this solution and it worked for me. I put both @cache_control(no_cache=True, must_revalidate=True, no_store=True) and @login_required as sees in the code below.

remeber to import cashe control.

It does not work if I leave one of these out. They work together. Just see the code below

from django.contrib.auth.decorators import login_required
from django.views.decorators.cache import cache_control
@cache_control(no_cache=True, must_revalidate=True, no_store=True)
@login_required(login_url='login')
def myview(request):
   return HttpResponse(render(request,'path_to_your_view.html'))

I am using django 2.1 and removed the forwardslashes in '/login/' and used 'login' instead
