web.py session

web.py session学习：

import web
from web import form

urls = (
'/','Index',
'/test','Test',
'/login','Login',
'/logout','Logout',
)

render = web.template.render(".")

allowed = (
('admin','123123'),
)

web.config.debug = False
app = web.application(urls, locals())
session = web.session.Session(app, web.session.DiskStore('sessions'))

class Index:
def GET(self):
if session.get('logged_in',False):
return '<h1>Login Success!!!</h1><a href="/test">test</a></br><a href="/logout">Logout</a>'
raise web.seeother('/login')

class Login:
def GET(self):
return render.login()
def POST(self):
i = web.input()
username = i.get('username')
passwd = i.get('passwd')
if (username,passwd) in allowed:
session.logged_in = True
web.setcookie('system_mangement', '', 60)
raise web.seeother('/')
else:
return '<h1>Login Error!!!</h1></br><a href="/login">Login</a>'

class Logout:
def GET(self):
session.logged_in = False
raise web.seeother("/login")

class Test:
def GET(self):
if session.get('logged_in',False):
return '<h1> test login success!!!</h1></br><a href="/logout">Logout</a>'
return '<h1>logout now</h1></br><a href="/login">Login</a>'

if __name__ == '__main__':
app.run()
