Base Authenticator

base authenticator使用简单的用户名与密码认证。

Authenticator.authenticate(handler, data)

该方法会传递Tornado的RequestHandler,以及JupyterHub登录表单的data。通常data包含两个键值:username和password。

自定义一个需要查找字典的Authenticator,只需要重写这个方法

from tornado import gen
from IPython.utils.traitlets import Dict
from jupyterhub.auth import Authenticator

class DictionaryAuthenticator(Authenticator):

    passwords = Dict(config=True,
        help="""dict of username:password for authentication"""
    )

    @gen.coroutine
    def authenticate(self, handler, data):
        if self.passwords.get(data['username']) == data['password']:
            return data['username']

results matching ""
