NodeJS 服务器基本模板

基本server配置

cookie / session / get数据 / post数据 / 请求方法

const express=require('express');
const static=require('express-static');
const cookieParser=require('cookie-parser');
const cookieSession=require('cookie-session');
const bodyParser=require('body-parser');
const multer=require('multer');
const consolidate=require('consolidate');

var server=express();

server.listen(8080);

//1.解析cookie
server.use(cookieParser('sdfasl43kjoifguokn4lkhoifo4k3'));

//2.使用session
var arr=[];
for(var i=0;i<100000;i++){
  arr.push('keys_'+Math.random());
}
server.use(cookieSession({name: 'zns_sess_id', keys: arr, maxAge: 20*3600*1000}));

//3.post数据
server.use(bodyParser.urlencoded({extended: false}));
server.use(multer({dest: './www/upload'}).any());

//4.配置模板引擎
//输出什么东西
server.set('view engine', 'html');
//模板文件放在哪儿
server.set('views', './views');
//哪种模板引擎
server.engine('html', consolidate.ejs);

//接收用户请求
server.get('/index', function (req, res){
  res.render('1.ejs', {name: 'blue'});
});

//4.static数据
server.use(static('./www'));

命令行

npm install express express-static cookie-parser cookie-session body-parser multer consolidate

基本路由配置

express路由功能

const express=require('express');

var server=express();

//目录1：/user/
var routeUser=express.Router();

routeUser.get('/1.html', function (req, res){   //http://xxx.com/user/1.html
  res.send('user1');
});
routeUser.get('/2.html', function (req, res){   //http://xxx.com/user/2.html
  res.send('user22222');
});

server.use('/user', routeUser);

//目录2：/article/
var articleRouter=express.Router();
server.use('/article', articleRouter);

articleRouter.get('/10001.html', function (req, res){   //http://xxxx.com/article/10001.html
  res.send('asdfasdfasdf');
});

server.listen(8080);
