問題ドクトリン2

でスリム3を使用しようとすると、私は次のようなメッセージが出ます：

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

私のインデックスファイルには、このようなものです：

<?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(); 

とInterventionsActionは、このようなものです：

<?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); 
    } 

}

私の質問は、おそらく私はいくつかの設定値を設定していないか、探しているはずの何かがありますか？

Answer 1

あなたのオートローダーがファイルを見つけられないと思います。あなたのcomposer.jsonで"autoload"セクションを検索し、そこに次のようなものを置く必要があります。

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

これは、ディレクトリのsrc /のみのApp-名前空間のクラスが含まれていることを前提としています。したがって、src/Action/InterventionAction.phpには、名前空間App\Action\InterventionActionを持つクラスが含まれていると見なされます。あなたのテストでは、 "autoload-dev"セクションで同等のことをしたいかもしれません。

オートローダーが新しい情報で確実に更新されるように、composer installまたはcomposer update --lockも実行する必要があります。

ます。また、クラスや作曲のドキュメントにファイル名を解決する方法を知っているオートロードPSRSを参照することもできます。
