express+mysql+vue,从零搭建一个商城管理系统15--快递查询（对接快递100）

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
快递鸟API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;

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"
}

}

免费版本试用100次

五、试错与误区

用于签名的param和get请求url上的param
必须是JSON.stringify(param)的JSON格式，
不能是Object格式，不然一直报签名错误

总结

踩坑路漫漫长@~@
