为了简化开发流程,使用了django 的用户管理机制。项目中需要实现sso单点登录,保障系统能够整合到原有旧平台中。
(1)在app中添加authbackend.py 。 yourapp/auth_backend.py
?1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
from django.contrib.auth.backends import ModelBackend
from django.contrib.auth.models import User
class PasswordlessAuthBackend(ModelBackend):
"""Log in to Django without providing a password.
"""
def authenticate( self , username = None ):
try :
return User.objects.get(username = username)
except User.DoesNotExist:
return None
def get_user( self , user_id):
try :
return User.objects.get(pk = user_id)
except User.DoesNotExist:
return None
|
(2)设置setting.py
?1 2 3 4 |
AUTHENTICATION_BACKENDS = (
# ... your other backends
'yourapp.authbackend.PasswordlessAuthBackend' ,
)
|
(3)在自己的view中可以直接使用
?1 2 |
user = authenticate(username = user.username)
login(request, user)
