Express.js – req.signedCookies Property
req.signedCookies contains the signed cookies (ready for use) sent by the request while using the cookie-parser middleware. Signed cookies exist in a different object to show the developer intent, else a malicious attack could be made on the request.cookie values that are relatively easy to spoof.
The property defaults are set to "{ }", if no cookies are sent.
Syntax
req.signedCookies
Installing the cookie-parser module
npm install cookie-parser
Example 1
Create a file with the name "reqSignedCookies.js" and copy the following code snippet. After creating the file, use the command "node reqSignedCookies.js" to run this code as shown in the example below −
// req.signedCookies() Method Demo Example // Importing the express & cookieParser module var cookieParser = require('cookie-parser'); var express = require('express'); // Initializing the express and port number var app = express(); // Initializing the router from express var router = express.Router(); var PORT = 3000; // Defining the cookieParser to be used app.use(cookieParser()); // Defining an api endpoint app.get('/api', function (req, res) { req.signedCookies.title='TutorialsPoint'; console.log(req.signedCookies); res.send(); }); app.listen(PORT, function(err){ if (err) console.log(err); console.log("Server listening on PORT", PORT); });
Output
Hit the following Endpoint with a GET request: localhost:3000/api
C:\home
ode>> node reqSignedCookies.js Server listening on PORT 3000 [Object: null prototype] { title: 'TutorialsPoint' }
Example 2
Let's take a look at one more example.
// req.signedCookies() Method Demo Example // Importing the express & cookieParser module var cookieParser = require('cookie-parser'); var express = require('express'); // Initializing the express and port number var app = express(); // Initializing the router from express var router = express.Router(); var PORT = 3000; // Defining the cookieParser to be used app.use(cookieParser()); // Defining an api endpoint app.get('/api', function (req, res) { // Setting multiple cookies req.signedCookies.title='Mayank'; req.signedCookies.age=21; console.log(req.signedCookies); res.send(); }); app.listen(PORT, function(err){ if (err) console.log(err); console.log("Server listening on PORT", PORT); });
Output
Hit the following Endpoint with a GET Request: localhost:3000/api
C:\home
ode>> node reqSignedCookies.js Server listening on PORT 3000 [Object: null prototype] { title: 'Mayank', age: 21 }
