Question

我正在学习本教程：here，当我更改为AbstractController时，出现以下错误：

Compile Error: Declaration of App\Controller\LuckyController::render() must be compatible with Symfony\Bundle\FrameworkBundle\Controller\AbstractController::render(string $view, array $parameters = Array, ?Symfony\Component\HttpFoundation\Response $response = NULL): Symfony\Component\HttpFoundation\Response

所以我检查了原始方法并添加了缺少的参数，但是现在我得到了

Compile Error: Declaration of App\Controller\LuckyController::render(string $view, array $parameters = Array, ?Symfony\Component\HttpFoundation\Response $response = NULL) must be compatible with Symfony\Bundle\FrameworkBundle\Controller\AbstractController::render(string $view, array $parameters = Array, ?Symfony\Component\HttpFoundation\Response $response = NULL): Symfony\Component\HttpFoundation\Response

这是我的代码：

    <?php
// src/Controller/LuckyController.php
namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;

class LuckyController extends AbstractController
{
    /**
     * @Route("/lucky/number")
     */
    public function render(string $view, array $parameters = [], Response $response = null)
    {
        $number = random_int(0, 100);

        return $this->render('lucky/number.html.twig', ['number' => $number]);

    }
}

我做错了什么？

好，所以我很傻。我应该将方法名称保留为“数字”

Symfony：渲染必须与Symfony \ Bundle \ FrameworkBundle \ Controller \ AbstractController :: render
