第一步 def demo(func): def inner(): print ('111111') func() return inner @demo def home(): print ('home') home() def book(): print ('book') def finance(): print('finance') 最简单的装饰器 第二步 user, passwd = 'yang', '123456' flag = False def demo(func): def inner(): global flag if flag == False: user_1 = input('please your name: ') passwd_1 = input('please your passwd: ') if user_1 == user and passwd_1 == passwd: flag = True print ('登录成功') func() else: print ('登录失败') elif flag == True: func() return inner @demo def home(): print ('home') @demo def book(): print ('book') home() book() 账号密码只认证一次 第三步 user, passwd = 'jd', 'jd123456' #JD账号 user1, passwd1= 'wx', 'wx123456' #wx账号 flag = False def args1(auth ='jd'): if auth =='jd': def demo(func): def inner(): global flag if flag == False: user_jd = input('please your name: ') passwd_jd = input('please your passwd: ') if user_jd == user and passwd_jd == passwd: flag = True print ('登录成功') func() else: print ('登录失败') elif flag == True: func() return inner return demo elif auth == 'wx': def demo(func): def inner(): global flag if flag == False: user_wx = input('please your name: ') passwd_wx = input('please your passwd: ') if user_wx == user1 and passwd_wx == passwd1: flag = True print('登录成功') func() else: print('登录失败') elif flag == True: func() return inner return demo @args1() def home(): print('home') @args1() def book(): print('book') home() book() 支持不同平台账号密码登录（wx or jd）
