In my application, I need to set a cookie using the express framework.I have tried the following code but it's not setting the cookie.
Can anyone help me to do this?
var express = require('express'), http = require('http');
var app = express();
app.configure(function(){
app.use(express.cookieParser());
app.use(express.static(__dirname + '/public'));
app.use(function (req, res) {
var randomNumber=Math.random().toString();
randomNumber=randomNumber.substring(2,randomNumber.length);
res.cookie('cokkieName',randomNumber, { maxAge: 900000, httpOnly: true })
console.log('cookie have created successfully');
});
});
var server = http.createServer(app);
var io = require('socket.io').listen(server);
server.listen(5555);
Not exactly answering your question, but I came across your question, while looking for an answer to an issue that I had. Maybe it will help somebody else.
My issue was that cookies were set in server response, but were not saved by the browser.
The server response came back with cookies set:
Set-Cookie:my_cookie=HelloWorld; Path=/; Expires=Wed, 15 Mar 2017 15:59:59 GMT
This is how I solved it.
I used fetch
in the client-side code. If you do not specify credentials: 'include'
in the fetch
options, cookies are neither sent to server nor saved by the browser, even though the server response sets cookies.
Example:
var headers = new Headers();
headers.append('Content-Type', 'application/json');
headers.append('Accept', 'application/json');
return fetch('/your/server_endpoint', {
method: 'POST',
mode: 'same-origin',
redirect: 'follow',
credentials: 'include', // Don't forget to specify this if you need cookies
headers: headers,
body: JSON.stringify({
first_name: 'John',
last_name: 'Doe'
})
})
I hope this helps somebody.
Setting cookie in the express is easy
npm install cookie parser
const cookieParser = require('cookie-parser');
app.use(cookieParser());
res.cookie('cookieName', '1', { expires: new Date(Date.now() + 900000), httpOnly: true })
console.dir(req.cookies.cookieName)
Set Cookie?
res.cookie('cookieName', 'cookieValue')
Read Cookie?
req.cookies
Demo
const express('express')
, cookieParser = require('cookie-parser'); // in order to read cookie sent from client
app.get('/', (req,res)=>{
// read cookies
console.log(req.cookies)
let options = {
maxAge: 1000 * 60 * 15, // would expire after 15 minutes
httpOnly: true, // The cookie only accessible by the web server
signed: true // Indicates if the cookie should be signed
}
// Set cookie
res.cookie('cookieName', 'cookieValue', options) // options is optional
res.send('')
})
Set a cookie:
res.cookie('cookie', 'monster')

Read a cookie:
(using cookie-parser middleware)
req.cookies['cookie']
