前言

需求：主要学习express，所以先写service部分
快递100API文档

一、安装md5，axios

npm install axios md5 --save-dev

二、新建config/logistics.js

config/logistics.js

//快递100
const axios = require('axios');
const md5 = require('md5');//查询物流信息url
let url= 'https://poll.kuaidi100.com/poll/query.do';
//customer
let customer = 'xxxxxxxxxxxxxxxxxxxxxxxxx';
//授权key
let key = 'xxxxxxxxx';const logistics = {query:async (param)=>{//一定要把param转换成JSON，不然一直报签名错误let paramJson =  JSON.stringify(param);let sign = md5(paramJson+key+customer);sign = sign.toUpperCase();axios.defaults.headers.get['Content-Type'] = 'application/x-www-form-urlencoded';const res = await axios.get(url+`?customer=${customer}&sign=${sign}&param=${paramJson}`);return res.data}
}module.exports = logistics;

customer，key通过快递100企业信息获取

customer对应customer
key对应授权key

三、修改routes/order.js

routes/order.js

const OrderDao = require('../dao/order');
const logistics = require('../config/logistics');
const OrderRoutes = (router)=>{router.post('/order/addGoodsToOrder',async (req,res)=>{const result = await OrderDao.addGoodsToOrder(req.body);res.json(result);});router.get('/order/queryGoodsByUserIdFromOrder',async (req,res)=>{const result = await OrderDao.queryGoodsByUserIdFromOrder(req.query);res.json(result);});router.post('/order/queryOrderLogistics',async (req,res)=>{const result = await logistics.query(req.body);res.json(result);});
}
module.exports = OrderRoutes;

在这里插入图片描述

四、查询物流信息

url:http://localhost:1990/order/queryOrderLogistics
params:{{"com": "yuantong","num": "xxxxxxxxxxx","phone": "","from": "","to": "","resultv2": "4","show": "0","order": "desc"
}}
