基于原生JS+node.js+mysql打造的简易前后端分离用户登录系统

引入依赖 var express = require(‘express‘); var url = require(‘url‘); var bodyParser = require(‘body-parser‘); var app = express();
// 核心逻辑模块 var sql = require(‘./login.js‘); app.use(bodyParser.urlencoded({ extended: true })); // 设置响应头 app.all(‘*‘, function(req, res, next) { res.header("Access-Control-Allow-Origin", "*"); res.header("Access-Control-Allow-Methods","PUT,POST,GET,DELETE,OPTIONS"); res.header(‘Access-Control-Allow-Headers‘,‘x-requested-with,content-type,Access-Control-Allow-Origin‘); res.header("X-Powered-By",‘ 3.2.1‘) res.header("Content-Type", "application/json;charset=utf-8"); next(); }); // 暴露接口 app.post(‘/user‘,function(req, res){ var query = url.parse(req.url,true).query; switch(query.ctr){ case ‘add‘: sql.catchres({type:‘INSERT‘,data:req.body},function(msg){ res.send(msg); }); break; case ‘update‘: sql.catchres({type:‘UPDATE‘,data:req.body},function(msg){ res.send(msg); }); break; case ‘delete‘: sql.catchres({type:‘DELETE‘,data:req.body},function(msg){ res.send(msg); }); break; case ‘login‘: sql.catchres({type:‘SELECT‘,data:req.body},function(msg){ res.send(msg); }); break; default: res.send(‘undefined contrl!‘); } }); // 监听端口 app.listen(‘8080‘,function(){ console.log(‘listen at 8080‘) })

 

三、运行

node app.js

我们的服务器就启动了，监听8080端口，我们向8080端口发起请求：
