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