【问题描述】:
我正在 Django 上创建一个 Web 应用程序。当登录用户单击“注销”时,注销页面正确显示。但是,当在浏览器中单击返回按钮时,用户可以再次重新进入会话。为了解决这个问题,我关注了这篇文章:Disable browser 'Back' button after logout?,并使用了 cache_control。但是,用户仍然可以通过单击后退按钮重新进入“关闭”会话。以下是相关代码:
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
)

我是 Django 和 Python 编码的新手,所以可能犯了一些基本错误。请帮忙
【问题讨论】:
-
您能告诉我们您的注销视图和 URL 模式吗?
-
另外,你确定他们“回到了会议中”吗?而不是简单地获取浏览器缓存页面?如果您单击注销 -> 后退按钮 -> 刷新;会发生什么?
