I started to use notification system on Slack provided by Laravel 5.4 and it is awesome (src: https://laravel.com/docs/5.4/notifications)!
However I have a problem to notify with a queue it triggers an Exception: Serialization of 'Closure' is not allowed in /var/www/project_test/vendor/laravel/framework/src/Illuminate/Queue/Queue.php:125
Can you help me please, what is my mistake ?
Information : - it works well without Queue - queue driver is database - queue worker is started with 'queue:work --queue=default,mail --sleep=3 --tries=3 --timeout=60'
Here my code in app/Notifications/Slack.php :
namespace App\Notifications;
use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\SlackMessage;
class Slack extends Notification implements ShouldQueue
{
use Queueable;
private $channel;
private $username;
private $icon;
private $message;
/**
* Create a new notification instance.
*
* @return void
*/
public function __construct(String $channel = '', String $username = '', String $icon = '', String $message = '')
{
$this->channel = $channel;
$this->username = $username;
$this->icon = $icon;
$this->message = $message;
}
/**
* Get the notification's delivery channels.
*
* @param mixed $notifiable
* @return array
*/
public function via($notifiable)
{
return ['slack'];
}
/**
* Get the Slack representation of the notification.
*
* @param mixed $notifiable
* @return SlackMessage
*/
public function toSlack($notifiable)
{
return (new SlackMessage)
->from($this->username, $this->icon)
->to($this->channel)
->content($this->message);
}
/**
* Get the array representation of the notification.
*
* @param mixed $notifiable
* @return array
*/
public function toArray($notifiable)
{
return [
'channel' => $this->channel,
'username' => $this->username,
'icon' => $this->icon,
'message' => $this->message,
];
}
}
Here my code in app/Providers/AppServiceProvider.php which use slack notifications:
namespace App\Providers;
use Queue;
use Carbon\Carbon;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Schema;
use Illuminate\Support\Facades\Log;
use Illuminate\Queue\Events\JobFailed;
use Illuminate\Notifications\Notifiable;
use App\Notifications\Slack;
class AppServiceProvider extends ServiceProvider
{
use Notifiable;
/**
* Route notifications for the Slack channel.
*
* @return string
*/
public function routeNotificationForSlack()
{
return \Config::get('slack.endpoint');
}
/**
* Bootstrap any application services.
*
* @return void
*/
public function boot()
{
// When a queue job fail
Queue::failing(function (JobFailed $event) {
// Notify team of failing job
$when = Carbon::now()->addSeconds(10);
$this->notify((new Slack('slack_channel', 'slack_username', 'slack_icon', 'Job Failed !'))->delay($when));
});
}
/**
* Register any application services.
*
* @return void
*/
public function register()
{
//
}
}
