在公共控制类中引入
import tornado.web from backend.session.session import BaseSession class BaseRequestHandler(tornado.web.RequestHandler): def initialize(self): self.session = BaseSession.get_session_handler(self)
在控制类中使用
class LoginHandler(BaseRequestHandler): def get(self): pass def post(self): #验证成功,缓存信息 self.session['username'] = ret.username self.session['email'] = ret.email
