Symfony #[CurrentUser] attribute returns null-CodePudding

<?php

declare(strict_types=1);

namespace App\Controller\User;

use App\Entity\User;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\Security\Http\Attribute\CurrentUser;

#[Route('/users', name: 'user.')]
class UserController extends AbstractController
{
    #[Route(name: 'list')]
    public function list(#[CurrentUser] ?User $user, Request $request): Response { 
        dd($user->getFirstName());
    }

Say's Call to a member function getFirstName() on null

But I'm authorized. At the Symfony Profiler it shows that I'm logged in.

Env: PHP 8.0.11 Symfony 5.3.9

CodePudding user response：

The correct details on solution are provided by https://stackoverflow.com/users/1144627/will-b Symfony #[CurrentUser] attribute returns null

The issue is caused by enabled ParamConvertor (sensio/framework-extra-bundle). It can't resolve the User due to lack definitions of how to fetch the Entity from DB, so it sets the $user variable to null because of nullable #[CurrentUser] ?User $user . If you want to keep functionality of param converter and #[CurrentUser] attribute same time, you should disable auto convertion #

config/packages/sensio_framework_extra.yaml
sensio_framework_extra:
    request:
        converters: true
        auto_convert: false

And define route params each time manually. Sources: https://symfony.com/bundles/SensioFrameworkExtraBundle/current/annotations/converters.html https://symfony.com/blog/new-in-symfony-5-2-controller-argument-attributes https://symfony.com/doc/current/controller/argument_value_resolver.html

CodePudding user response：

if your controller extends "AbstractController" you can use $this->getUser() to get the current User.

in your list function you are not giving an user id neither an $user so $user is rationally null

#[Route('/users', name: 'user.')]
class UserController extends AbstractController
 {
#[Route(name: 'list')]
public function list( Request 
$request): Response { 
    dd($this->getUser()->getFirstName());
}
