Laravel:如何获取自动递增的id并通过电子邮件发送

$user = new User;
$id = $user->id;

use Illuminate\Support\Facades\Mail;
use App\Mail\YourMailClass;

$mailData = [
    'id' => $id,
    // 其他邮件内容数据
];

Mail::to('recipient@example.com')->send(new YourMailClass($mailData));

namespace App\Mail;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;

class YourMailClass extends Mailable
{
    use Queueable, SerializesModels;

    public $mailData;

    public function __construct($mailData)
    {
        $this->mailData = $mailData;
    }

    public function build()
    {
        return $this->subject('Your Subject')
                    ->view('emails.your-template')
                    ->with($this->mailData);
    }
}
