1.node

原始：
var http = require( 'http' )
var server = http.createServer()
server.on( 'request', function(req res){
var url = req.url
if(url = '/'){
res.setHeader( 'content-Type', 'text/plain; charset = utf-8' ) //根據型別設定，html裡自帶有，fs裡第二個引數可直接加 'utf8'
res.end('請求成功了')
}
})
server.listen(3000, function ( ) { '
 
伺服器啟動成功' })


簡化：
vat http = require( 'http' )
http
.createServer(req, res){
var url = req.url
if(url = '/'){
res.end('ok')
}
}
.listen(3000, function ( ) { '伺服器啟動成功' })

2.express

var express = require( 'express' )
var app = express.server ()
app.get( '/', function(req, res){
res.send( '請求成功了' )
)
app.listen(
 
300, function(){console.log('伺服器啟動成功')})


//  路由
var express = require ( 'express' )
var router = express.Router ()
router.get( '/' , function(req, res){
res.render( 'index.html', {stus: syus}) //要先下載 art-template express-art-template 包用以渲染頁面
})
module.exports = router
