使用 cookie 解析器设置 cookie

以下是使用 cookie-parser 模块设置和读取 cookie 的示例 ：

var express = require('express');
var cookieParser = require('cookie-parser'); // module for parsing cookies
var app = express();
app.use(cookieParser());

app.get('/setcookie', function(req, res){
    // setting cookies
    res.cookie('username', 'john doe', { maxAge: 900000, httpOnly: true });
    return res.send('Cookie has been set');
});

app.get('/getcookie', function(req, res) {
    var username = req.cookies['username'];
    if (username) {
        return res.send(username);        
    }

    return res.send('No cookie found');
});

app.listen(3000);
