Cookies are transfered <a href="http://en.wikipedia.org/wiki/HTTP_cookie" rel="noreferrer">through HTTP-Headers</a> 
You'll only have to parse the request-headers and put response-headers.

blocks|key|1182332|text|没有快速的函数访问来获取/设置cookie，所以我想出了以下技巧：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1182333|var+http+=+require('http');

function+parseCookies+(request)+{

++++++++rc+=+request.headers.cookie;

}).listen(8124);

console.log('Server+running+at+http://127.0.0.1:8124/');|code-block|syntax|javascript|1182334|这会将所有cookie存储到cookies对象中，并且您需要在写入头部时设置cookie。|1182335|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

There is no quick function access to getting/setting cookies, so I came up with the following hack:

<pre><code>var http = require('http');

function parseCookies (request) {
 var list = {},
 rc = request.headers.cookie;

 rc &amp;&amp; rc.split(';').forEach(function( cookie ) {
 var parts = cookie.split('=');
 list[parts.shift().trim()] = decodeURI(parts.join('='));
 });

 return list;
}


http.createServer(function (request, response) {

 // To Read a Cookie
 var cookies = parseCookies(request);

 // To Write a Cookie
 response.writeHead(200, {
 'Set-Cookie': 'mycookie=test',
 'Content-Type': 'text/plain'
 });
 response.end('Hello World\n');
}).listen(8124);

console.log('Server running at http://127.0.0.1:8124/');
</code></pre>

This will store all cookies into the cookies object, and you need to set cookies when you write the head.

If you're using the express library, as many node.js developers do, there is an easier way. Check the Express.js documentation page for more information.

The parsing example above works but express gives you a nice function to take care of that:

<pre><code>app.use(express.cookieParser());
</code></pre>

To set a cookie:

<pre><code>res.cookie('cookiename', 'cookievalue', { maxAge: 900000, httpOnly: true });
</code></pre>

To clear the cookie:

<pre><code>res.clearCookie('cookiename');
</code></pre>

Here's a neat copy-n-paste patch for managing cookies in node. I'll do this in CoffeeScript, for the beauty.

<pre><code>http = require 'http'

http.IncomingMessage::getCookie = (name) -&gt;
 cookies = {}
 this.headers.cookie &amp;&amp; this.headers.cookie.split(';').forEach (cookie) -&gt;
 parts = cookie.split '='
 cookies[parts[0].trim()] = (parts[1] || '').trim()
 return

 return cookies[name] || null

http.IncomingMessage::getCookies = -&gt;
 cookies = {}
 this.headers.cookie &amp;&amp; this.headers.cookie.split(';').forEach (cookie) -&gt;
 parts = cookie.split '='
 cookies[parts[0].trim()] = (parts[1] || '').trim()
 return

 return cookies

http.OutgoingMessage::setCookie = (name, value, exdays, domain, path) -&gt;
 cookies = this.getHeader 'Set-Cookie'
 if typeof cookies isnt 'object'
 cookies = []

 exdate = new Date()
 exdate.setDate(exdate.getDate() + exdays);
 cookieText = name+'='+value+';expires='+exdate.toUTCString()+';'
 if domain
 cookieText += 'domain='+domain+';'
 if path
 cookieText += 'path='+path+';'

 cookies.push cookieText
 this.setHeader 'Set-Cookie', cookies
 return
</code></pre>

Now you'll be able to handle cookies just as you'd expect:

<pre><code>server = http.createServer (request, response) -&gt;
 #get individually
 cookieValue = request.getCookie 'testCookie'
 console.log 'testCookie\'s value is '+cookieValue

 #get altogether
 allCookies = request.getCookies()
 console.log allCookies

 #set
 response.setCookie 'newCookie', 'cookieValue', 30

 response.end 'I luvs da cookies';
 return

server.listen 8080
</code></pre>

 return cookies;
};

<pre><code>get_cookies(request)['my_cookie']

RevNoah had the best answer with the suggestion of using Express's <a href="https://github.com/expressjs/cookie-parser" rel="noreferrer">cookie parser</a>. But, that answer is now 3 years old and is out of date. 

Using <a href="http://expressjs.com/" rel="noreferrer">Express</a>, you can read a cookie as follows 

<pre><code>var express = require('express');
var cookieParser = require('cookie-parser');
var app = express();
app.use(cookieParser());
app.get('/myapi', function(req, resp) {
 console.log(req.cookies['Your-Cookie-Name-Here']);
})
</code></pre>

And update your <code>package.json</code> with the following, substituting the appropriate relatively latest versions.

<pre><code>"dependencies": {
 "express": "4.12.3",
 "cookie-parser": "1.4.0"
 },
</code></pre>

More operations like setting and parsing cookies are described <a href="https://github.com/expressjs/cookie-parser" rel="noreferrer">here</a>
and <a href="http://expressjs.com/" rel="noreferrer">here</a>

blocks|key|1182552|text|首先需要创建cookie+(我将令牌封装在cookie中作为示例)，然后在response.To中设置它。按照以下方式使用cookie安装cookieParser|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1182553|app.use(cookieParser());|code-block|syntax|javascript|1182554|浏览器会将其保存在它的'Resource‘标签中，并将用于此后的每个请求，并将初始URL作为基础|1182555|var+token+=+student.generateToken('authentication');

First one needs to create cookie (I have wrapped token inside cookie as an example) and then set it in response.To use the cookie in following way install cookieParser

<pre><code>app.use(cookieParser());
</code></pre>

The browser will have it saved in its 'Resource' tab and will be used for every request thereafter taking the initial URL as base

<pre><code>var token = student.generateToken('authentication');
 res.cookie('token', token, {
 expires: new Date(Date.now() + 9999999),
 httpOnly: false
 }).status(200).send();
</code></pre>

To get cookie from a request on the server side is easy too.You have to extract the cookie from request by calling 'cookie' property of the request object.

<pre><code>var token = req.cookies.token; // Retrieving Token stored in cookies
</code></pre>

blocks|key|968288|text|如果您不关心cookie中的内容，并且只想使用它，那么可以使用request+(一种流行的节点模块)尝试这种干净的方法：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|968289|var+request+=+require('request');

If you don't care what's in the <code>cookie</code> and you just want to use it, try this clean approach using <a href="https://github.com/request/request" rel="nofollow noreferrer"><code>request</code></a> (a popular node module): 

<pre><code>var request = require('request');
var j = request.jar();
var request = request.defaults({jar:j});
request('http://www.google.com', function () {
 request('http://images.google.com', function (error, response, body){
 // this request will will have the cookie which first request received
 // do stuff
 });
});
</code></pre>

I want to be able to set a single cookie, and read that single cookie with each request made to the nodejs server instance. Can it be done in a few lines of code, without the need to pull in a third party lib?

<pre><code>var http = require('http');

http.createServer(function (request, response) {
 response.writeHead(200, {'Content-Type': 'text/plain'});
 response.end('Hello World\n');
}).listen(8124);
