Laravel Mailable队列，如何将自定义数据传递给MessageSent事件

Question

I am using Laravel Mailable to send email, and I want to log the email that was successfully sent.

Laravel Mailable have default event that was fired after the email was sent

https://laravel.com/docs/5.6/mail#events

So I hook my listener to this event

protected $listen = [
        'App\Events\Event' => [
            'App\Listeners\EventListener',
        ],
        'Illuminate\Mail\Events\MessageSent' => [
            'App\Listeners\LogSentEmailNotification',
        ],
    ];

Listener handler

public function handle(MessageSent $event)
{

    //get extra data 
    $job_request_id = $event->message->job_request_id;

    $message = $event->message;

    $data = [
        'job_request_id' => $job_request_id,
        'to' => $message->getHeaders()->get('To'),
        'from' => $message->getHeaders()->get('From'),
        'cc' => $message->getHeaders()->get('Cc'),
        'bcc' => $message->getHeaders()->get('Bcc'),
        'subject' => $message->getHeaders()->get('Subject')->getFieldBody(),
        'body' => $message->getBody(),
    ];

    $email_notification_log = $this->email_notification_log->create($data);
}

The extra data job_request_id is passed from the build() method in Mailable class, CustomEmailNotification.php

class CustomEmailNotification extends Mailable implements ShouldQueue
{

    public function build()
    {
        $job_request_id = 1;

        //pass extra data mail message            

        $this->withSwiftMessage(function ($message) use($job_request_id){
            $message->job_request_id = $job_request_id;
        });
    }
}

Right now this line on Listener class is working fine without queue, however when using queue it will return null

 //get extra data 
 $job_request_id = $event->message->job_request_id;
 var_dump($job_request_id);
 //null when using queue

Question is, what is the correct way to pass custom data to MailSent event when using queue?

Or is there possibility job_request_id is lost when using queue and pass to withSwiftMessage(), so the Event Listener just received null value?

Thanks

If you're using Supervisor as queue worker. Try restarting all the process. Supervisor must be reloaded to reflect the recent changes from your code.

sudo supervisorctl restart all
