django - Django 2.1.5 身份验证（登录/注销）在浏览器后退按钮上中断

问题描述

我使用开箱即用的 django LoginView 和 LogoutView 创建了一个简单的登录注销应用程序。在我的应用程序中，我可以使用 CreateView 进行注册，使用 ListView 列出用户并使用 DetailView 获取用户详细信息。

当我单击浏览器的后退按钮时，我看到登录和注销问题。问题：

登录后，我被重定向到索引页面。但是，当我单击后退按钮时，我会返回登录页面并可以使用其他有效用户登录。
注销后，我被重定向到索引页面。但是，当我单击返回按钮时，我可以查看登录数据，例如列表页面和详细信息页面。

我的应用程序（帐户）的代码是：

settings.py
<code>
LOGIN_REDIRECT_URL = "/accounts/"
LOGOUT_REDIRECT_URL = "/accounts/"


project urls.py
<code>
urlpatterns = [
path("admin/", admin.site.urls),
path("accounts/", include("django.contrib.auth.urls")),
path("accounts/", include("accounts.urls")),
]


app urls.py
<code>

from . import views

urlpatterns = [

path("login/", auth_views.LoginView.as_view(),name='login'),
path("logout/", auth_views.LogoutView.as_view(), name="logout"),
path("signup/", views.SignUp_cview.as_view(), name="signup_curl"),
