间间间间简陋版书城系统
编写小说阅读程序实现下属功能
一:程序运行开始时显示
0 账号注册
1 充值功能
2 阅读小说
二: 针对文件db.txt,内容格式为:"用户名:密码:金额",完成下述功能
2.1、账号注册
2.2、充值功能
三:文件story_class.txt存放类别与小说文件路径,如下,读出来后可用eval反解出字典
{"0":{"0":["倚天屠狗记.txt",3],"1":["沙雕英雄转.txt",10]},"1":{"0":["令人羞耻的爱.txt",6],"1":["二狗的妻子与大草原的故事.txt",5]},}
3.1、用户登录成功后显示如下内容,根据用户选择,显示对应品类的小说编号、小说名字、以及小说的价格
"""
0 玄幻武侠
1 都市爱情
2 高效养猪36技
"""
3.2、用户输入具体的小说编号,提示是否付费,用户输入y确定后,扣费并显示小说内容,如果余额不足则提示余额不足
四:为功能2.2、3.1、3.2编写认证功能装饰器,要求必须登录后才能执行操作
五:为功能2.2、3.2编写记录日志的装饰器,日志格式为:"时间 用户名 操作(充值or消费) 金额"
附加:可以拓展作者模块,作者可以上传自己的作品
