Laravel 5.2事件處理錯誤

Question

我最近更新Laravel從5.0到5.2，但它似乎事件處理已經改變了一下。

當我在Listener中使用$ event變量時，我不斷收到這個令人討厭的錯誤。 這裏是牽連代碼：

<?php 

namespace App\Listeners; 

use App\Events\UserWasCreated; 

use Illuminate\Contracts\Mail\MailQueue; 
use Illuminate\Queue\InteractsWithQueue; 
use Illuminate\Contracts\Queue\ShouldQueue; 

use Lang; 

class UserCreated implements ShouldQueue 
{ 
    /** 
    * @var Mailer 
    */ 
    private $mailer; 

    /** 
    * Create the event listener. 
    * 
    * @param Mailer $mailer 
    */ 
    public function __construct(MailQueue $mailer) 
    { 
     $this->mailer = $mailer; 
    } 

    /** 
    * Handle the event. 
    * 
    * @param UserWasCreated $event 
    * @return void 
    */ 

    public function handle(UserWasCreated $event) 
    { 
      $data = array('password' => $event->user->password, 'username' => $event->user->username, 'email' => $event->user->email); 

      $this->mailer->queue('emails.user_created', $data, function($message) use ($data) 
      { 
        $message->to($data['email'])->subject(Lang::get('notifications.USER_CREATED_EMAIL_SUBJECT', [], $event->user->lang)); 
      }); 
    } 
} 

以下是錯誤和堆棧跟蹤：

Answer 1

您需要$事件傳遞給封閉

public function handle(UserWasCreated $event) 
{ 
     $data = array('password' => $event->user->password, 'username' => $event->user->username, 'email' => $event->user->email); 

     // Pass event to the closure - use($data, $event) 
     $this->mailer->queue('emails.user_created', $data, function($message) use ($data, $event) 
     { 
       $message->to($data['email'])->subject(Lang::get('notifications.USER_CREATED_EMAIL_SUBJECT', [], $event->user->lang)); 
     }); 
} 

Answer 2

嘗試傳遞$事件進入關閉狀態：

$this->mailer->queue('emails.user_created', $data, function($message) use ($data, $event) 

編輯，嘗試設置語言首先，檢查這兩個值：

// including app instance 
use Illuminate\Foundation\Application; 

public function handle(UserWasCreated $event, Application $app) 
{ 
    $lang = $event->user->lang; 
    $app->setLocale($lang); 
    $data = array('password' => $event->user->password, 'username' => $event->user->username, 'email' => $event->user->email); 

    // no need to pass the event, because the locate is already set 
    $this->mailer->queue('emails.user_created', $data, function($message) use ($data){ 
     $message->to($data['email'])->subject(Lang::get('notifications.USER_CREATED_EMAIL_SUBJECT')); 
    }); 
} 

Answer 3

的解決方案，建議：

<?php 

namespace App\Listeners; 

use App\Events\UserWasCreated; 

use Illuminate\Contracts\Mail\MailQueue; 
use Illuminate\Queue\InteractsWithQueue; 
use Illuminate\Contracts\Queue\ShouldQueue; 
use Illuminate\Foundation\Application; 

use Lang; 

class UserCreated implements ShouldQueue 
{ 
    /** 
    * @var Mailer 
    */ 
    private $mailer; 
    private $app; 
    /** 
    * Create the event listener. 
    * 
    * @param Mailer $mailer 
    */ 
    public function __construct(MailQueue $mailer, Application $app) 
    { 
     $this->mailer = $mailer; 
     $this->app = $app; 
    } 

    /** 
    * Handle the event. 
    * 
    * @param UserWasCreated $event 
    * @return void 
    */ 

    public function handle(UserWasCreated $event) 
    { 
      $lang = $event->user->lang; 
      $this->app->setLocale($lang); 
      $data = array('code' => $event->user->email_confirmation_code, 'username' => $event->user->username, 'email' => $event->user->email); 

      // no need to pass the event, because the locate is already set 
      $this->mailer->queue('emails.user_created', $data, function($message) use ($data) 
      { 
       $message->to($data['email'])->subject(Lang::get('notifications.USER_CREATED_EMAIL_SUBJECT')); 
      }); 

    } 
}
