1.项目概述

1.1项目主要内容

1、用户登录

1.1 商品浏览（所有和单独查询）

1.2 商品的购买(数量-1，加上一个时间)

1.3 用户订单查询(不可修改，可以删除)

2、管理员登录

2.1、商品添加

2.2 、商品的查询

2.3、商品的删除

2.4、商品的修改

2.5、可以查询订单(并修改)

1.2项目需求分析

实现管理员的登录与用户登录,注册。
能够及时对修改后的数据进行存储；
对数据中的商品信息处理
对商品信息的增加、删除、修改和查询；
对商品信息的存储；

2.公共类设计

类的层次采用如下结构，由于pyhton的性质，方法封装到每个类中。

3.有关接口

存储的文件名称,josn中不支持单引号字符串

goodstable_filename="./data/goodstable.json"

ordertable_filename="./data/ordertable.json"

Register_table_filename='./data/Register_table.json'

manager_table_filename='./data/manager_table.json'

宏字典的键

difine_user_id="difine_user_id"

difine_ordertable="difine_ordertable"

difine_goods_id='difine_goods_id'

difine_goods_name='difine_goods_name'

difine_buytime='difine_buytime'

difine_goods_number='difine_goods_number'

difine_goods_price='difine_goods_price'

difine_user_password='difine_user_password'

difine_user_type='difine_user_type'

管理员初始id和密码: ID:1234 密码:1234

difine_manager_id="1234"

difine_manager_password="1234"

接口示例

1.商品

{'difine_goods_id': '1', 'difine_goods_name': '1', 'difine_goods_price': 1, 'difine_goods_number': 1}

2.订单

{'difine_user_id': '1001', 'difine_ordertable': "[{'difine_goods_id': '2', 'difine_goods_name': '2', 'difine_buytime': '2'}, {'difine_goods_id': '2', 'difine_goods_name': '2', 'difine_buytime': '2'}, {'difine_goods_id': '2', 'difine_goods_name': '2', 'difine_buytime': '2'}, {'difine_goods_id': '2', 'difine_goods_name': '2', 'difine_buytime': '2'}]"}

3.用户注册表

[{"difine_user_id": "1002", "difine_user_password": '1122', 'difine_user_type': 'user'}, {'difine_user_id': '1004', 'difine_user_password': '11', 'difine_user_type': 'user'}]

difine_user_type =字符型

管理员:manager

用户:user

difine_goods_number =整型

difine_goods_price =整型
