我想通过 session 进行登录和注销。但我收到错误。

"Attempted to call an undefined method named "getRequest" of class "AppBundle\Controller\DefaultController".

这是我的DefaultController.php 

<?php

namespace AppBundle\Controller;
use AppBundle\Entity\users;
use AppBundle\Entity\Login;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Session\Session;



class DefaultController extends Controller
{
    /**
     * @Route("/login", name="login")
     */

    public function loginAction(Request $request)
    {

        $session=$this->getRequest()->getSession();
        $em=$this->getDoctrine()->getEntityManager();
        $repository=$em->getRepository('AppBundle:users');


        if($request->getMethod()=='POST')
        {

        $session->clear();
        $username=$request->get('username');
        $password=$request->get('password');
        $remember=$request->get('remember');





        $user=$repository->findOneBy(array('userName'=>$username, 'password'=>$password)); 



        if($user)
        {
            if($remember=='remember-me')
            {
                $login=new Login();
                $login->setUserName($username);
                $login->setPassword($password);
                $session->set('login', $login);
            }
            return $this->render('default/welcome.html.twig', array('name' =>$user->getFirstName()));

        }
        else
            {
            return $this->render('default/login.html.twig', array('name' => 'Login Error'));
        }
    }
    else{

        if($session->has('login'))
        {
            $login=$session->get('login');
            $username=$login->getUserName();
            $password=$login->getPassword();
            $user=$repository->findOneBy(array('userName'=>$username, 'password'=>$password));

    if($user)
        {   
    return $this->render('default/welcome.html.twig', array('name' =>$user->getFirstName()));
        }       

        }

        return $this->render('default/login.html.twig');
    } 
    }



    /**
     * @Route("/signupe", name="signupe")
     */

    public function signupeAction(Request $request)
    {
            if($request->getMethod()=='POST'){

                $username=$request->get('username');
                $firstname=$request->get('firstname');
                $password=$request->get('password');

                $user = new Users();
                $user->setFirstName($firstname);
                $user->setPassword($password);

            $em=$this->getDoctrine()->getEntityManager();
            $em->persist($user);
            $em->flush();



    }   

    return $this->render('default/signupe.html.twig');

}

    /**
     * @Route("/logout", name="logout")
     */

    public function logoutAction(Request $request)
    {
    $session=$this->getRequest()->getSession();
    $session->clear();

最佳答案

Symfony Controller 中的

getRequest() 方法自 2.4 版以来已被弃用，并在 3.0 中被删除。您已经注入(inject)了 $request 对象，因此只需使用 $request->getSession()。

关于javascript - 试图调用类 "getRequest"的名为 "AppBundle\Controller\DefaultController"的未定义方法，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45934989/
