尝试将 Slim 3 与 Doctrine 2 一起使用的问题

Question

我收到以下消息：

Slim Application Error
The application could not run because of the following error:

#10 {main}

我的索引文件是这样的：

<?php
use \Psr\Http\Message\ServerRequestInterface as Request;
use \Psr\Http\Message\ResponseInterface as Response;
use App\Action\InterventionsAction;

require 'vendor/autoload.php';


$app = new \Slim\App([
    'settings' => [
        'displayErrorDetails' => true
    ]
]);
$app->get('/hello/{name}', function (Request $request, Response $response) {
    $name = $request->getAttribute('name');
    $response->getBody()->write("Hello,, $name");

    return $response;
});
$app->get('/api/interventions', function (Request $request, Response $response) {
    $int = new InterventionsAction($em);

    $response->getBody()->write("Hello,, ");

    return $response;
});
$app->run();

而 InterventionsAction 是这样的：

<?php
namespace App\Action;

use Doctrine\ORM\EntityManager;

final class InterventionsAction
{
    private $em;

    public function __construct(EntityManager $em)
    {
        $this->em = $em;
    }

    public function fetch($request, $response, $args)
    {
        $interventions = $this->em->getRepository('App\Entity\Interventions')->findAll();
        $interventions = array_map(
            function ($interventions) {
                return $interventions->getArrayCopy();
            },
            $interventions
        );
        return $response->withJSON($interventions);
    }

}

所以我的问题是我可能设置了一些错误的配置值，或者是否缺少我应该寻找的东西？

Answer 1

我假设您的自动加载器找不到文件。您应该在 composer.json 中搜索 "autoload" 部分，然后在其中放置类似以下内容的内容：

"autoload": {
    "psr-4: {
        "App\": "src/",
    }
}

这假定您的目录 src/ 仅包含来自 App 命名空间的 classes。所以 src/Action/InterventionAction.php 期望包含一个带有命名空间 App\Action\InterventionAction 的 class。对于您的测试，您可能希望在 "autoload-dev" 部分中执行等效操作。

您还必须运行 composer install 或 composer update --lock 以确保使用新信息更新自动加载器。

您可能还想阅读自动加载 PSR 以了解如何将文件名解析为 classes 和作曲家文档：
