Django自定义登录验证

登录不一定只通过username登录也可通过email或mobile登录

要达成此效果需要重写authenticate方法

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

from . models import UserProfile

class CustomBackend(ModelBackend):
    def authenticate(self, request, username=None, password=None, **kwargs):
        try:
            user = UserProfile.objects.get(Q(username=username)|Q(mobile=username)|Q(email=username))
            if user.check_password(password):
                return user
        except Exception as e:
            return None

 

在settings.py中配置authenticate走自定义的方法

# 自定义authenticate
AUTHENTICATION_BACKENDS = (
    'users.views.CustomBackend',
)
