Question

使用django rest构建一个restful API。我也想用内置的django管理功能。我使用./manage.py createsuperuser命令创建了一个超级用户。当我尝试使用正确的凭据登录创建的用户时，我无法。在研究中，我发现我的设置中没有AUTHENTICATION_BACKEND。我添加了身份验证后端，但是没有用。

我的settings.py文件：

import os

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))


# Quick-start development settings - unsuitable for production

DEBUG = False

当我尝试在shell中进行身份验证时，它返回None。

>>> from django.contrib.auth import authenticate
>>> my = authenticate(username='admin',password='password123')
>>> print(my)
None

Answer 1

您需要将SessionAuthenticationMiddleware添加到您的中间件。

'django.contrib.auth.middleware.SessionAuthenticationMiddleware',

Answer 2

我终于解决了问题，在设置中将MIDDLEWARE更改为MIDDLEWARE_CLASSES，它就像一个魅力。

而且我真的不需要明确指定AUTHENTICATION_BACKENDS。

无法验证超级用户或登录Django的管理站点，我做错了什么？
