Web.py session用户认证

调试一个用session来认证用户的程序 大概是这个样子 基本上可以当作webpy session认证的示例程序了

#!/usr/bin/env python
#coding=utf-8
import web
import time

urls = (
    '/', 'index',
    '/xml', 'pushxml',
    '/login', 'login',
    '/logout', 'logout',
)
render = web.template.render('templates/')
web.config.debug = False
app = web.application(urls, locals())
session = web.session.Session(app, web.session.DiskStore('sessions'))      

class index():
    def GET(self):
        try:
            if session.logged_in == True:
                return '
You are logged in
Logout'
        except AttributeError:
            pass
        return '
You are not logged in.
Login now'

def authorize(func):
    def logged(*args,**dic):
        if session.logged_in==True:
            func(*args,**dic)
        else:
            raise web.seeother('/login')
    return logged

class pushxml():
    # @authorize
    def GET(self):
        try:
            if session.logged_in == True:
                web.header('Content-Type', 'text/xml')
                i = web.input(data=None)
                return render.response(i.data)
        except AttributeError:
            pass
       
class login():
    def GET(self):
        try:
            session.logged_in = False
        except AttributeError:
            pass
        return """
            

                

                    

                        
User: 
                        

                    
                    

                        
Password: 
                        

                    
                    

                        

                        

                    
                
            
        """
           
    def POST(self):
        login_data = web.input()
        if login_data.user == 'a' and login_data.passwd == 'a':
            session.logged_in = True
            print "posted"
            print session
            raise web.seeother('/')
       
class logout():
    def GET(self):
        try:
            session.logged_in = False
            session.kill()
        except AttributeError:
            pass
        raise web.seeother('/')

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

  开始的时候为了方便web.config.debug = True（这是默认值） session总是不能保存 经过相当长时间的纠结发现错误竟然出在这里

web.config.debug = False

如上 关掉debug模式session可以正常保存了 究竟失身么原因我也搞不清楚了 今天才看到 http://webpy.org/cookbook/sessions

sessions doesn’t work in debug mode because it interfere with reloading. see session_with_reloader for more details.

FUCK web.py！！！
