tornado-cookies+pycket 验证

1.pip install pycket

 pip install redis

2.config

settings = dict(
            debug=True,
            template_path='templates',
            static_path='static',       cookie_secret='secret',
            pycket={
                'engine': 'redis',
                'storage': {
                    'host': 'localhost',
                    'port': 6379,
                    'db_sessions': 2,
                    # 'password': '',
                    'db_notifications': 11,
                    'max_connections': 2 ** 31,
                },
                'cookies': {
                    'expires_days': 30,
                    'max_age': 5000
                }
            },
        )

 3.构建BaseHandler

from pycket.session import SessionMixin

class BaseHandler(tornado.web.RequestHandler, SessionMixin):
    def get_current_user(self):
        return self.session.get('cookie_name')

4.需要设置一个条件去验证,比如要求用户登录。就在用户登录的handler中设置一个cookie信息

class LoginHandler(BaseHandler):
  def get(self):
     username = self.get_argument('username')
    passwd = self.get_argument('password')
    if username in db and passwd == db.passwd:
      self.sesion.set('cookie_name', value)
      self.write('success login')

5.其他handler需要继承basehandler才能够使用装饰起@tornado.web.authenticated去验证用户是否登录

class NoLoginNoShow(BaseHandler):
  @tornado.web.authenticated
  def get(self):
    self.write('this message is secrect'

6.退出,可以通过self.session.delete('cookie_name')
