提示：学习express，搭建管理系统

---

前言

需求：主要学习express，所以先写service部分

一、新建config/area.js

内容太多，没办法粘贴，资源里自取

二、新建models/address.js

models/address.js

const { DataTypes } = require('sequelize');
const sequelize = require('../config/db');

const AddressModel = sequelize.define('Address',{
    id: {
        type: DataTypes.INTEGER,
        autoIncrement: true,
        primaryKey: true
    },
    addressId:{
        type:DataTypes.STRING ,
        comment:'地址ID',
    },
    createId:{
        type:DataTypes.STRING ,
        comment:'创建人ID',
    },
    createName:{
        type:DataTypes.STRING ,
        comment:'创建人姓名',
    },
    provinceCode:{
        type:DataTypes.STRING ,
        comment:'省code',
    },
    provinceName:{
        type:DataTypes.STRING ,
        comment:'省',
    },
    cityCode:{
        type:DataTypes.STRING ,
        comment:'市code',
    },
    cityName:{
        type:DataTypes.STRING ,
        comment:'市',
    },
    areaCode:{
        type:DataTypes.STRING ,
        comment:'县code',
    },
    areaName:{
        type:DataTypes.STRING ,
        comment:'县',
    },
    fullAddress:{
        type:DataTypes.STRING(255),
        comment:'详细地址',
    },
    recipientName:{
        type:DataTypes.STRING ,
        comment:'收件人',
    },
    phone:{
        type:DataTypes.STRING(30),
        comment:'手机号码',
    },
},{
    tableName:'address'
});

//无address表创建address表
AddressModel.sync();
module.exports = AddressModel;

三、新建dao/address.js

dao/address.js

const AddressModel = require('../models/address');
const md5 = require('md5');
const secretKey = 'longlongago';

const errFun = (msg,code)=>{
    return {
        code:code||500,
        success:false,
        msg:msg||'操作失败'
    }
}
const sucFun = (data,msg)=>{
    return {
        code:200,
        success:true,
        msg:msg||'操作成功',
        data,
    }
}
const AddressDao = {
    //添加地址
    addAddress:async(data)=>{
        //生成addressId
        const addressId = md5(data.createdId+secretKey+new Date().getTime());
        //添加address
        try {
            const address = await AddressModel.create({...data,addressId});
            if(!address) errFun('添加地址失败！');
            return sucFun(address,'添加地址成功！')
        }catch(err){
            return errFun('添加失败');
        }
    },
    //获取用户地址列表
    queryAddressListByUserId:async(data)=>{
        //根据userId查询address
        try{
            const addressList = await AddressModel.findAll({createId:data.createId});
            if(addressList&&addressList.length>0)return sucFun(addressList,'查询用户地址列表成功');
            return errFun('查询用户地址列表失败');
        }catch(err){
            return errFun('查询失败');
        }
    },
}

module.exports = AddressDao;

四、新建routes/address.js

const AddressDao = require('../dao/address');
const AREA = require('../config/area');
const AddressRoutes = (router)=>{
    //添加地址
    router.post('/address/addAddress',async (req,res)=>{
        const result = await AddressDao.addAddress(req.body);
        res.json(result);
    });
    //获取用户地址列表
    router.post('/address/queryAddressListByUserId',async (req,res)=>{
        const result = await AddressDao.queryAddressListByUserId(req.body);
        res.json(result);
    });
    //获取省市县
    router.get('/address/getPCA',async (req,res)=>{
        
        res.json(AREA);
    });
}
module.exports = AddressRoutes;

五、添加地址

url:http://localhost:1990/address/addAddress
params:{
    "createId":"9e14ebba3be0ae546374e8f5a49f9e80",
    "createName":"long001",
    "provinceCode":"110000",
    "provinceName":"北京市",
    "cityCode":"110100",
    "cityName":"市辖区",
    "areaCode":"110108",
    "areaName":"海淀区",
    "fullAddress":"西小口路xxxxxxxxxxxxx",
    "recipientName":"zzz",
    "phone":"1891193zzzz"
}
params:{
    "createId":"9e14ebba3be0ae546374e8f5a49f9e80",
    "createName":"long001",
    "provinceCode":"110000",
    "provinceName":"北京市",
    "cityCode":"110100",
    "cityName":"市辖区",
    "areaCode":"110108",
    "areaName":"海淀区",
    "fullAddress":"五道口路xxxxxxxxxxxxx",
    "recipientName":"xxx",
    "phone":"1891193xxxx",
}

六、查询用户地址列表

url:http://localhost:1990/address/queryAddressListByUserId
params:{
   "createId": "9e14ebba3be0ae546374e8f5a49f9e80"
}
