就是另一个不同的登陆backend。
而DJANGO会尝不同的方式，哪个成功就用哪个
authentication.py
from django.contrib.auth.models import User
class EmailAuthBackend(object):
def authenticate(self, username=None, password=None):
try:
user = User.objects.get(email=username)
if user.check_password(password):
return user
return None
except User.DoesNotExist:
return None
def get_user(self, user_id):
try:
return User.objects.get(pk=user_id)
except User.DoesNotExist:
return None
setting.py中加一个认证方式：
AUTHENTICATION_BACKENDS = (
'django.contrib.auth.backends.ModelBackend',
'account.authentication.EmailAuthBackend',
)
