在node中借助express-session使用session

var express = require('express');

var session = require('express-session');

var app = express();

app.use(session({secret:'ylx',cookie:{maxAge:60000}}))

//存session

app.get('/', function(req, res) {
  var sess = req.session
  sess.username = req.body['username'];
})

//取session

app.get('/', function(req, res) {
 console.log(req.session.username)
})
