express中cookie-parser的简单使用

/* cookie的读取和存储 */
var express = require(‘express‘);
var cookieParser = require(‘cookie-parser‘);
var app = express();
app.use(cookieParser());

// 获取cookie记录
app.get(‘/‘,function (req,res) {
    var arr = [];
    for (var key in req.cookies){
    // console.log(req.cookies[key])
        for(var i = 0;i < req.cookies[key].length;i++){
        arr.push(decodeURI(req.cookies[key][i]))
        }

    }
    res.send(‘浏览记录‘ + arr)
})

// 存储cookie  eg:http://127.0.0.1:3000/trip?area=杭州
app.get(‘/trip‘,function (req,res) {
    // 获取区域
    var area = encodeURI(req.query.area);
    // 读取该区域的cookie值，我们以数组形式存储 eg:[‘browsercookie‘]
    var areaCookie = req.cookies.area || [];

    areaCookie.push(area)
    // console.log(areaCookie)
    // maxAge失效时间 以毫秒为单位
    res.cookie(area,areaCookie,{maxAge:15 * 60 * 1000,httpOnly:true})
    res.send(decodeURI(area) + ‘旅游‘)
})
app.listen(3000);
