回答by Jonathan Lonowski
As Express is built on Connect, you can use the cookieParsermiddlewareand req.cookiesto read and res.cookie()to write cookies:
由于 Express 是基于Connect构建的，因此您可以使用cookieParser中间件并req.cookies读取和res.cookie()写入 cookie：
// configuration
app.use(express.cookieParser());
// or `express.cookieParser('secret')` for signed cookies
// routing
app.get('/foo', function (req, res) {
res.cookie('bar', 'baz');
// ...
});
app.get('/bar', function (req, res) {
res.send(req.cookies.bar);
});

[更新]
As of Express 4.0, Connect will no longer be included with Expressand the default middleware have been moved into their own packages, including cookie-parser.
从 Express 4.0 开始，Connect 将不再包含在 Express 中，并且默认中间件已移动到它们自己的包中，包括cookie-parser.

You could just use the response object that express provides to set your cookies.
您可以使用 express 提供的响应对象来设置您的 cookie。
You can find detailed information on how to do that at: http://expressjs.com/en/api.html#res.cookie
