Can't set a cookie using NextJS 9's API Route

问题

Typically it seems that when using Express, in the "res" object there is "cookie" so you can do something like:

res.cookie('session', sessionCookie, options);

In the API routes offered by NextJS in Next 9, when looking at res, this does not exist. Is there a way to set the cookie for a response object in a Next API Route function?

回答1:

Adapted from offical repo middleware example, you can set Set-Cookie header via res like so:

import { serialize } from 'cookie';

function (req, res) {
   // ...
   res.setHeader('Set-Cookie', serialize('token', 'token_cookie_value', { path: '/' }));
}
