本文实例为大家分享了tornado实现登录和登出的具体代码，供大家参考，具体内容如下
main.py如下：
import tornado.httpserver
import tornado.ioloop
import tornado.web
import tornado.options
import os.path
from tornado.options import define, options
define("port", default=8000, help="run on the given port", type=int)
class BaseHandler(tornado.web.RequestHandler):
def get_current_user(self):
return self.get_secure_cookie("username")
class LoginHandler(BaseHandler):
def get(self):
self.render('login.html')
def post(self):
self.set_secure_cookie("username", self.get_argument("username"))
self.redirect("/")
class WelcomeHandler(BaseHandler):
@tornado.web.authenticated
def get(self):
self.render('index.html', user=self.current_user)
class LogoutHandler(BaseHandler):
def post(self):
if (self.get_argument("logout", None)):
self.clear_cookie("username")
self.redirect("/")
if __name__ == "__main__":
tornado.options.parse_command_line()
settings = {
"template_path": os.path.join(os.path.dirname(__file__), "templates"),
"cookie_secret": "bZJc2sWbQLKos6GkHn/VB9oXwQt8S0R0kRvJ5/xJ89E=",
"login_url": "/login"
}
application = tornado.web.Application([
(r'/', WelcomeHandler),
(r'/login', LoginHandler),
(r'/logout', LogoutHandler)
],debug= True,**settings)
http_server = tornado.httpserver.HTTPServer(application)
http_server.listen(options.port)
tornado.ioloop.IOLoop.instance().start()
index.html
<html>
<head>
</head>
<body>
<p>Hello {{ user }}</p>
<form action="/logout?logout=1" method="post">
<input type="submit" value="Log out"></br>
