＝＝用express起一个server，访问静态资源
var express = require('express');
var path = require('path');
var app = express();
//set static file
app.use(express.static(path.join(__dirname, 'www')));
var server = app.listen(9000,function(){
console.log('server is listening...')
})
//set router
app.get('/',function(req, res){
res.send('Welcome To Express Server!')
})
