我的索引文件是這樣的：

<?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(); 

和InterventionsAction是這樣的：

<?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); 
    } 

}

所以我的問題是我可能設置了錯誤的一些配置值，或者是有一些我應該找的東西？

Answer 1

我假定您的自動加載器找不到文件。你應該尋找在你的composer.json的"autoload"部分，並把類似的東西在那裏執行以下操作：

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

這是假設你的src /目錄僅包含從App-命名空間的類。所以src/Action/InterventionAction.php期望包含一個名字空間爲App\Action\InterventionAction的類。對於你的測試，你可能想在「autoload-dev」部分做相同的操作。

您還必須運行composer install或composer update --lock以確保自動裝載機更新爲新信息。

你也可能需要閱讀的自動加載的PSR知道如何解決文件名類和作曲家文檔：

• http://www.php-fig.org/psr/psr-0/（過時）
• http://www.php-fig.org/psr/psr-4/
• https://getcomposer.org/doc/04-schema.md#autoload
