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addressIdconst addressId = md5(data.createdId+secretKey+new Date().getTime());//添加addresstry {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addresstry{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"
}
