As an enhancement to @Corey Hart's answer, I've rewritten the parseCookies()
using:
Here's the working example:
let http = require('http');
function parseCookies(str) {
let rx = /([^;=\s]*)=([^;]*)/g;
let obj = { };
for ( let m ; m = rx.exec(str) ; )
obj[ m[1] ] = decodeURIComponent( m[2] );
return obj;
}
function stringifyCookies(cookies) {
return Object.entries( cookies )
.map( ([k,v]) => k + '=' + encodeURIComponent(v) )
.join( '; ');
}
http.createServer(function ( request, response ) {
let cookies = parseCookies( request.headers.cookie );
console.log( 'Input cookies: ', cookies );
cookies.search = 'google';
if ( cookies.counter )
cookies.counter++;
else
cookies.counter = 1;
console.log( 'Output cookies: ', cookies );
response.writeHead( 200, {
'Set-Cookie': stringifyCookies(cookies),
'Content-Type': 'text/plain'
} );
response.end('Hello World\n');
} ).listen(1234);
I also note that the OP uses the http module. If the OP was using restify, he can make use of restify-cookies:
var CookieParser = require('restify-cookies');
var Restify = require('restify');
var server = Restify.createServer();
server.use(CookieParser.parse);
server.get('/', function(req, res, next){
var cookies = req.cookies; // Gets read-only cookies from the request
res.setCookie('my-new-cookie', 'Hi There'); // Adds a new cookie to the response
res.send(JSON.stringify(cookies));
});
server.listen(8080);
