<html>
<head>
<title>首页</title>
</head>
<body>
<div>这是首页,当前登录用户是:<span style="color:green">`currentuser`</span>
</div>

服务端代码
登陆逻辑:
UserClass.py
#coding:utf-8
class UserLogin:
UserName=""
UserPass=""
def __init__(self,uname,upass):
self.UserName=uname
self.UserPass=upass
def Login(self):
if self.UserName=="shenyi" and self.UserPass=="123":
return True
return False
业务逻辑:
如果登陆成功，就设置cookies,跳转index
# -*- coding: utf-8 -*-

from UserClass import UserLogin
为从文件中导入类
cookie
就是通过浏览器和服务器沟通后，私下保存在用户电脑里某个文件夹的一个文件。
