import web
web.config.debug = False
urls=(
‘/‘,‘index‘,
‘/count‘,‘count‘,
‘/reset‘,‘reset‘
)
app = web.application(urls,locals())
#session is be stored on disk. 将session保存在本地磁盘上。
session = web.session.Session(app,web.session.DiskStore(‘sessions‘),
initializer={‘count‘:0})
class count:
def GET(self):
session.count += 1
return str(session.count)
class reset:
def GET(self):
session.kill()
return ""
if __name__ == "__main__":
app.run()
第二种，将浏览器session会话的信息，保存在数据库mysql中。
表结构如下：
create table sessions(
session_id char(128) UNIQUE NOT NULL,
atime timestamp NOT NULL default current_timestamp,
data text )

#session is be stored database 将session信息保存在数据库中。
db = web.database(dbn=‘mysql‘,db=‘py‘,user=‘root‘,pw=‘123456‘)
store = web.session.DBStore(db,‘sessions‘)
session = web.session.Session(app,store,initializer={‘count‘:0})
render = web.template.render(‘template/‘,globals={‘context‘:session})
class index:
def GET(self):
return render.index()
class count:
def GET(self):
session.count += 1
return str(session.count)
class reset:
def GET(self):
session.kill()
return ""
if __name__ == "__main__":
app.run()
index.html文件如下：
<!doctype html>
<html>
<head>
<title>test sessions</title>
</head>
<body>
<h1>
<span>
You are logged in as <b> $context.count </b>
