地址簿,指的是消费者用户的地址信息,用户登录成功后可以维护自己的地址信息。同一个用户可以有多个地址信息,但是只能有一个默认地址。
对于地址簿管理,有以下几个功能:
根据上述原型图先粗粒度设计接口,共包含7个接口。
接口设计:
接下来细粒度分析每个接口,明确每个接口的请求方式、请求路径、传入参数和返回值。
2). 查询登录用户所有地址
3). 查询默认地址
6). 根据id查询地址
7). 设置默认地址
用户的地址信息会存储在address_book表,即地址簿表中。具体表结构如下:
字段名 | 数据类型 | 说明 | 备注 |
---|---|---|---|
id | bigint | 主键 | 自增 |
user_id | bigint | 用户id | 逻辑外键 |
consignee | varchar(50) | 收货人 | |
sex | varchar(2) | 性别 | |
phone | varchar(11) | 手机号 | |
province_code | varchar(12) | 省份编码 | |
province_name | varchar(32) | 省份名称 | |
city_code | varchar(12) | 城市编码 | |
city_name | varchar(32) | 城市名称 | |
district_code | varchar(12) | 区县编码 | |
district_name | varchar(32) | 区县名称 | |
detail | varchar(200) | 详细地址信息 | 具体到门牌号 |
label | varchar(100) | 标签 | 公司、家、学校 |
is_default | tinyint(1) | 是否默认地址 | 1是 0否 |
这里面有一个字段is_default,实际上我们在设置默认地址时,只需要更新这个字段就可以了。
