Symfony和php在会话中查找用户数据 - Symfony and php finding user data in session

我需要解码从我的会话数据返回的这个Symfony代码块，然后找到那个人的用户ID，用户名和电子邮件。所以我设法获取这样的数据，但不适用于用户信息部分：

$session =  $this->get('session');
$userSee = $session->get('_security_user.context')->getToken()->getUser();
var_dump($session);

结果：

 object(Symfony'Component'HttpFoundation'Session'Session)#105 (3) {
  ["storage":protected]=>
  object(Symfony'Component'HttpFoundation'Session'Storage'NativeSessionStorage)#107 (5) {
    ["bags":protected]=>

返回$userSee时出错

<b>Fatal error</b>:  Call to a member function getToken() on string in <b>'GameModulesController.php</b> on line <b>157</b><br />

如果你的控制器扩展Symfony'Bundle'FrameworkBundle'Controller'Controller，你可以调用方法getUser()。

例如：

namespace AppBundle'Controller;
use Sensio'Bundle'FrameworkExtraBundle'Configuration'Route;
use Symfony'Bundle'FrameworkBundle'Controller'Controller;
/**
 * Default controller
 *
 * @Route("/app")
 */
class DefaultController extends Controller
{
    /**
     * @Route("/", name="app_index")
     */
    public function indexAction()
    {
        dump($this->getUser());
        return $this->render('default/index.html.twig');
    }
}

要在symfony2中检索用户信息，你有2种方式取决于你的symfony版本：

$user = $this->get('security.context')->getToken()->getUser();警告：这是不推荐使用的方法，不要在Symfony 2.6及更高版本中使用它
$user = $this->get('security.token_storage')->getToken()->getUser();：这是symfony的主要方法官方，未弃用
