【问题描述】：

我正在一个名为 Sylius 的框架中做一个 API，它使用 symfony 框架作为基础。解决 API 逻辑的 API 控制器类目前无法识别我

我有一个带有各自声明的控制器：

<?php

declare(strict_types=1);

namespace EasyCommerce\ShopApiPlugin\Controller\Order;

use EasyCommerce\ShopApiPlugin\Factory\ValidationErrorViewFactoryInterface;
use EasyCommerce\ShopApiPlugin\Request\Order\CustomerOrderCancellationRequest;
use FOS\RestBundle\View\View;
use FOS\RestBundle\View\ViewHandlerInterface;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Messenger\MessageBusInterface;
use Symfony\Component\Validator\Validator\ValidatorInterface;

final class CustomerOrderCancellationAction
{
    /** @var ViewHandlerInterface */
    private $viewHandler;

    /** @var MessageBusInterface */
    private $bus;

    /** @var ValidatorInterface */
    private $validator;

    /** @var ValidationErrorViewFactoryInterface */
    private $validationErrorViewFactory;

    public function __construct(
        ViewHandlerInterface $viewHandler,
        MessageBusInterface $bus,
        ValidatorInterface $validator,
        ValidationErrorViewFactoryInterface $validationErrorViewFactory
    ) {
        $this->viewHandler = $viewHandler;
        $this->bus = $bus;
        $this->validator = $validator;
        $this->validationErrorViewFactory = $validationErrorViewFactory;
    }

    public function __invoke(Request $request): Response
    {
        $pickupRequest = new CustomerOrderCancellationRequest($request);
        $validationResults = $this->validator->validate($pickupRequest);

        if (0 === count($validationResults)) {
            $this->bus->dispatch($pickupRequest->getCommand());

            return $this->viewHandler->handle(View::create(null, Response::HTTP_NO_CONTENT));
        }

        return $this->viewHandler->handle(View::create($this->validationErrorViewFactory->create($validationResults), Response::HTTP_BAD_REQUEST));
    }
}

控制器声明如下：

<service id="sylius.shop_api_plugin.controller.order.customer_order_cancellation_action"
                 class="EasyCommerce\ShopApiPlugin\Controller\Order\CustomerOrderCancellationAction"
        >
            <argument type="service" id="fos_rest.view_handler" />
            <argument type="service" id="sylius_shop_api_plugin.command_bus" />
            <argument type="service" id="validator" />
            <argument type="service" id="sylius.shop_api_plugin.factory.validation_error_view_factory" />
 </service>

我通过以下方式声明路由：

sylius_shop_api_customer_order_cancellation:
    path: /orders/{tokenValue}/cancellation
    methods: [PUT]
    defaults:
        _controller: sylius.shop_api_plugin.controller.order.customer_order_cancellation_action

它返回以下错误：

{
  "code": 500,
  "message": "Attempted to load class \"CustomerOrderCancellationAction\" from namespace \"EasyCommerce\\ShopApiPlugin\\Controller\\Order\".\nDid you forget a \"use\" statement for another namespace?"
}

为了测试路由是否配置正确，我将它指向另一个控制器并且它可以工作。问题出在您创建的控制器上。

【问题讨论】：

该代码在项目中的位置以及如何自动加载其类？
我可以用 composer dump-autoload 来解决它。谢谢

标签： php api rest symfony sylius

【解决方案1】：

由于主项目中有两个不同的命名空间，我不得不清除缓存：

bin/console cache:clear --env=dev

然后重新加载作曲家：

composer dump-autoload

这样它会重新加载所有命名空间
