cookie在nodejs express中使用

1.设置 res.cookie()

• res.cookie('name', 'koby', { domain: '.example.com', path: '/admin', secure: true });
• cookie的有效期为900000ms
• res.cookie('rememberme', '1', { expires: new Date(Date.now() + 900000), httpOnly: true });
• cookie的有效期为900000ms
• res.cookie('rememberme', '1', { maxAge: 900000, httpOnly: true });
• cookie的value为对象
• res.cookie('cart', { items: [1,2,3] });
• res.cookie('cart', { items: [1,2,3] }, { maxAge: 900000 });
• res.cookie('name', 'tobi', { signed: true });

2.获取 req.cookies

3.删除 res.clearCookie("option")
