$app->get('/setcookie', function ($request, $response) {
// $container is in router available as $this
$response = $this->cookies->setCookie('some_cookie', 'some cookie value', 3600);
return $response;
});$app->get('/readcookie', function ($request, $response) {
// all cookies
$allCookies = $request->getCookieParams();
// individual cookie
$someCookie = $this->cookies->some_cookie;
// do something here...
....
return $response;
});$app->get('/cookiedelete', function ($request, $response) {
$response = $this->cookies->deleteCookie('some_cookie');
return $response;
