Cookie都搞不定了，writeHead or render?

我用了ejs模版，所以需要render. res.render(‘index’, {title: ‘Express’}); res.writeHead(200,{ ‘Set-Cookie’:‘myCookie=“type=ninja”, “language=javascript”;path="/";Expires=’+timeObj+’;httpOnly=true’ });

不管先执行哪个都报错：Error: Can’t set headers after they are sent. 怎么办？writeHead没有回调吧？

 response.setHeader(
        'Set-Cookie', serialize(key, val, {path: "/", expires: exp})
    );
	好吧 ，还得多看书
