本文实例讲述了Django自定义认证方式。分享给大家供大家参考，具体如下：

创建登录应用

首先创建一个新的login app，用来存放认证用到代码

python manage.py startapp login

修改settings.py中的认证项

AUTHENTICATION_BACKENDS = (
  'login.auth.UsernamePasswordAuth',
)

自定义认证类

在login app下创建auth.py文件，内容如下

#coding:utf-8
from django.contrib.auth.models import User
class UsernamePasswordAuth(object):
  def authenticate(self, username=None, password=None):
    print("UsernamePasswordAuth.authenticate")
    try:
      user = User.objects.get(username__iexact=username)
      if user.check_password(password):
        return user
    except User.DoesNotExist:
      return None
  def get_user(self, user_id):
    print("UsernamePasswordAuth.get_user")
    try:
      user = User.objects.get(pk=user_id)
      return user
    except User.DoesNotExist:
      return None
