The example in this article describes the usage of session and cookie in Symfony2. Share it with everyone for your reference, the details are as follows:

session operation:

1. Set Session:

public function testSetSession() {
  $session = $this->getRequest()->getSession();
  $session->set($sessionName, $sessionValue );
}

2 . Get Session:

public function testGetSession() {
 $session = $this->getRequest()->getSession();
 $username = $session->get($sessionName);
}

3. Clear Session:

public function testClearSession() {
  $session = $this->getRequest()->getSession();//清除session
  $session->clear();
}

cookie operation:

use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Cookie;
public function testSetCookie($name, $value, $expire=0){
 $response = new Response();
 $response->headers->setCookie(new Cookie($name, $value, time() + $expire));
 $response->send(); // 包括 sendHeaders()、sendContent()
}
