如何解決反射異常類驗證不存在錯誤

Question

我最近的一些代碼工作，我得到這個錯誤：反射異常類驗證程序不上線20

存在這是最後一批代碼有錯誤，是前臺服務提供商：

/** 
* Register bindings 
* 
* @return void 
*/ 
public function register() 
{ 
    $this->repositories(); 

    $this->app->bind('\Desk\Forms\MessageForm', function($app) { 
     $validator = $app['validator']->make([], []); (line 20) 
     return new \Desk\Forms\MessageForm($validator); 
    }); 
} 

/** 
* Register Repositories 
*/ 
protected function repositories() 
{ 

    $this->app->bindShared('\Desk\Repositories\MessageRepository', function($app) { 
     $record = new \Desk\Records\MessageRecord; 
     return new \Desk\Repositories\MessageRepository($record); 
    }); 
} 

服務提供商：

/** 
* Register bindings 
* 
* @return void 
*/ 
public function register() 
{ 
    $this->registerSupport(); 
} 

控制器：

protected $messageForm; 

public function __construct(MessageForm $messageForm, MessageRepository $messageRepository, 
    MessageRecord $messageRecord) 
{ 
    $this->messageForm = $messageForm; 
    $this->messageRepository = $messageRepository; 
    $this->messageRecord = $messageRecord; 
} 

/** 
* Display a listing of the resource. 
* GET /messages 
* 
* @return Response 
*/ 
public function index() 
{ 
    return View::make('message.create'); 
} 

的app.config

'providers' => array(

    'Illuminate\Foundation\Providers\ArtisanServiceProvider', 
    'Illuminate\Auth\AuthServiceProvider', 
    'Illuminate\Cache\CacheServiceProvider',

Answer 1

似乎是爲您的自定義提供程序的代碼。您可能應該在providers部分的末尾添加app/config/app.php文件，並在'Illuminate\Validation\ValidationServiceProvider'之後定義它，因爲這裏是$validator已創建。

正如我所說的去app/config/app.php文件，並找到部分與

'providers' => array(

開始現在編輯你的供應商列表，把你的供應商在你的供應商列表的末尾：

'providers'  => array(

    // here all list of all default providers 
    // here your custom provider 
), 

編輯

然後您應該嘗試更改：

$validator = $app->make('validator')->make([], []); 

到

$validator = $app['validator']->make([], []);
