Django:有2个cookie会话,但是当管理员应用程序登录时,app会被注销(反之亦然)

标签: django session-cookies django-middleware

我想要有2个会话,一个用于我的应用程序(myapp.com),另一个用于管理员(myapp.com/admin)。有了这个,我可以访问我的Web客户端的不同选项卡,而无需在每次我想使用其中一个时登录。这很刺激。

我已经创建了一个新的会话中间件来控制它。

在我的设置文件中:

SESSION_COOKIE_NAME='usersessionid'
ADMIN_SESSION_COOKIE_NAME='adminsessionid'

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',

    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'core.utils.middleware.AdminCookieSessionMiddleware'
]

但是,我还有一个问题,即如果登录其中一个应用程序,我会自动退出另一个。

我正在追踪会话密钥,有时两个coockies都是一样的。这可以吗?如果没有,问题应该是什么?

答案 0 :(得分:0)

好的,我可以解决它,因此我发布了答案,所以我可以帮助某人尝试这样做。我从django SessionMiddleware复制代码并添加了一个cookie_name函数。在里面我创造了应该满足我需求的逻辑。 请务必将settings.SESSION_COOKIE_NAME替换为cookie_name。

这非常重要:在设置中,在MIDDELWARE列表中,您必须添加它,但默认情况下也会删除SessionMiddleware。将其插入正常SessionMiddleware所在的相同位置。我们的想法是将它放在&#d; django.contrib.auth.middleware.AuthenticationMiddleware'之前,否则,您将收到错误。

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    #'django.contrib.sessions.middleware.SessionMiddleware',
    'core.utils.middleware.MySessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
