問(wèn)題描述

先上目錄結(jié)構(gòu)

路由層代碼 router/

index.js

'use strict';module.exports = function (app) { app.get(’/’, function (req, res, next) {res.send(’Hello node-express World!’);next(); }); // 具體的業(yè)務(wù)請(qǐng)求路由配置 app.use(’/user’, require(’./user’)); // 404 page ejs渲染報(bào)錯(cuò)，暫時(shí)不管 app.use(function (req, res) {if (!res.headersSent) { res.status(404); // res.status(404).render(’../view/404’);} });};

user.js

'use strict';var express = require(’express’);var router = express.Router();//mysqlvar user_pool = require('../mysql/user');// 該路由使用的中間件 timeLogrouter.use(function timeLog(req, res, next) { console.log(’Time: ’, Date.now()); next();});// 定義網(wǎng)站主頁(yè)的路由router.get(’/’, function (req, res) { // console.log(req); res.send(req.query || {});});// 查詢(xún)用戶(hù)信息router.post(’/infos’, function (req, res) { console.log(req.body); user_pool.query('select * from user where name=1104', function (data) {console.log('===============user query callback==========');console.log(data);res.send(data); });});//moremodule.exports = router;

數(shù)據(jù)層代碼 mysql/ mysql_pool.js

/** * Created by xiaogang on 2017/4/5. */'use strict';var config = require(’config-lite’);var mysql = require(’mysql’);var pool = mysql.createPool(config.mysql_pool);module.exports = pool;

user.js

/** * Created by xiaogang on 2017/4/5. */'use strict';var pool = require('./mysql_pool');exports.query = function (sql, callback) { pool.query(sql, function (error, results, fields) {if (error) throw error;callback(JSON.parse(JSON.stringify(results))); });}exports.update = function (sql, callback) { pool.query(sql, function (error, results, fields) {if (error) throw error;callback(JSON.parse(JSON.stringify(results))); });}

前端調(diào)用：zepto(jquery) 的ajax

問(wèn)題：不知道各位經(jīng)常寫(xiě)后臺(tái)的認(rèn)為這樣封裝可行不？希望多多吐槽。

前端開(kāi)發(fā)轉(zhuǎn)node,目前只能封裝到這一步，后面要上項(xiàng)目的，還望多多指教。

問(wèn)題解答

百度搜索sequelize,可以使用這個(gè)orm來(lái)操作數(shù)據(jù)庫(kù)，雖然性能方面會(huì)有些一影響，但是使用方便
