问题描述

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

推荐答案

As Express建立在 Connect ，则可以使用 cookieParser middleware 和 req.cookies 阅读并 res.cookie（） 写入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起， Connect将不再包含在Express 中，并且默认中间件已移至自己的软件包中，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.
