symfony2 symofny3中得到get post session cookies的方法

symfony升级以后，废弃了以前的post,get等方法

之前是这样写的,直接上代码咯

public function webTestAction(Request $request)
    {
        //symfony2的get
        $this->getRequest()->get();
        //symfony3的get
        $test = $request->query->get('test');
        
        //symfony2的post
        $this->getRequest()->post();
        //symfony3的post
        $test = $request->request->get('test');
        
        return $this->render('test.html.twig', array(
        ));
    }

session的操作，

1.symfony2的session日常操作

　　1.set session 生成session

public function testSetSession() {
      $session = $this->getRequest()->getSession();
      $sessionValue = array(
            array('username' => 'gaofei','password' => 12),
        );
      $session->set('userinfo', $sessionValue );
}

　　2.Get Session 拿取session

　　

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

　　3.Clear Session清除session

　　

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

2.symfony3的session操作

　　set session

public function sessionAction(Request $request)
    {
        $session = $request->getSession();
        $sessionValue = array(
            array('username' => 'gaofei','password' => 12),
        );
        $session->set('userinfo', $sessionValue );
    }

　　get session

 public function sessionAction(Request $request)
    {
        $session = $request->getSession();
        $username = $session->get('userinfo');
        var_dump($username);exit;
    }

　　清除session

　　注意：这里我clear内不需要参数的。我这样尝试想删除一个key为user的session但是还是全部删除了，这块我自己实践是这样的，但是大家如果可以删除单个key的话希望大家传授我经验

public function sessionAction(Request $request)
    {
        $session = $request->getSession();
        $sessionValue = array(
            array('username' => 'gaofei','password' => 22222),
        );
        $sessionValueTwo = array(
            array('username' => 'gaofei','password' => 11111111),
        );
        $session->set('user', $sessionValue );
        $session->set('userinfo', $sessionValueTwo);

        $session->clear('user');
        $testTwo = $session->get('userinfo');
        var_dump($testTwo,$testTwo);exit;
    }

cookies的一些操作

　　symfony3系列的操作（都放在一起了）

　　

public function cookieAction(Request $request)
    {
        $response = new Response();
        $name = 'test';
        $value = '123';
        $expire = '1000';
        $nametwo = 'www';
        $response->headers->setCookie(new Cookie($name, $value, time() + $expire));
        $response->headers->setCookie(new Cookie($nametwo, $value, time() + $expire));
        $response->send(); // 包括 sendHeaders()、sendContent()
        $test = $request->cookies->get('www');
        var_dump($test);
    }

　　symfony2的操作

　　　　set cookies

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()
}

　　Get Cookie

　　

public function testGetCookie() {
   $request = $this->getRequest();
 
   return $request->cookies->all();
}

　　

Clear Cookie

public function testClearCookie() {
   $response = new Response();
   $response->headers->setCookie(new Cookie($name, $value, -1));
   $response->send();
}
