自定义django用户认证类

编写认证类

from django.db.models import Q
from django.contrib.auth.backends import ModelBackend
from .models import User


class UserModelBackend(ModelBackend):
    def authenticate(self, request, username=None, password=None, **kwargs):
        filter_q = Q()
        filter_q.connector = 'OR'
        # 用户名登录
        filter_q.children.append(
            Q(('username', username))
        )
        # 手机号登录
        filter_q.children.append(
            Q(('phone', username))
        )
        user = User.objects.filter(filter_q).first()
        if user and user.check_password(password) and self.user_can_authenticate(user):
            return user

 

修改配置文件指定认证类

#Django默认认证类
AUTHENTICATION_BACKENDS = ['django.contrib.auth.backends.ModelBackend']

#我们自己指定的类
AUTHENTICATION_BACKENDS = [
    'user.utils.LyUserModelBackend'
]
