如何修复 symfony 错误：无法自动装配

Question

请告诉我，如何修复 symfony 错误：无法自动装配“App\Controller\ArticleController::create()”的参数 $request：它引用了类“Symfony\Component\BrowserKit\Request”，但不存在此类服务。控制器：use App\Entity\Article;use App\Form\ArticleType;use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;use Symfony\Component\BrowserKit\Request;use Symfony\Component\Routing\Annotation\Route;/** * @Route("/article/create", name="creates_article") */public function create(Request $request){    $article = new Article();    $form = $this->createForm(ArticleType::class, $article);    $form->handleRequest($request);    return $this->render('article/form.html.twig', [        'form' => $form->createView()    ]);}日志：频道 - 请求Matched route "creates_article".{"route": "creates_article","route_parameters": {    "_route": "creates_article",    "_controller": "App\\Controller\\ArticleController::create"},"request_uri": "http://symfony.loc/article/create","method": "GET"}

我很确定，您使用了错误Request的类名称空间。

它应该是 ：

Symfony\Component\HttpFoundation\Request

代替

Symfony\Component\BrowserKit\Request

所以尝试：

use Symfony\Component\HttpFoundation\Request;

Symfony 文档中的示例： https ://symfony.com/doc/current/controller.html#the-request-object-as-a-controller-argument

use Symfony\Component\HttpFoundation\Request;

public function index(Request $request, $firstName, $lastName)

{

    $page = $request->query->get('page', 1);

    // ...

}
