I'm developing a website with node.js and express. How can I set a cookie value?

推荐答案

由于 Express 建立在 Connect 之上，您可以使用cookieParser 中间件 和 req.cookies 阅读和res.cookie() 写 cookie:

As Express is built on Connect, you can use the cookieParser middleware and req.cookies to read and res.cookie() to write cookies:

// 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);
});

[Update]

从 Express 4.0 开始，将不再包含连接与 Express 和默认中间件 已移入它们自己的包，包括 cookie-parser.

As of Express 4.0, Connect will no longer be included with Express and the default middleware have been moved into their own packages, including cookie-parser.
