Laravel 队列不作为后台运行

你好，我创建了一个 Laravel 队列作业来发送邮件

public function handle() {
    foreach($this->emails as $value) {
            $to         = $value->email;
            $subject    = $this->data['subject'];       
            $this->data['t_firstname']    = $value->firstname;
            $this->data['t_lastname']     = $value->lastname;
            if (view()->exists('mail.requirement_to_tutor')) {
                    $view = view('mail.requirement_to_tutor',$this->data);
                    $html = $view->render();
            }
            file_put_contents('test.txt', 'test database');
            $body = $html;
            $headers  = "From: " . $this->data['from'] . "\r\nReply-To: " . $this->data['from'] . "";
            $headers .= "MIME-Version: 1.0\r\n";
            $headers .= "Content-type: text/html; charset: utf8\r\n";
            mail($to, $subject, $body, $headers);
    }
}

我还从仓库推送数据

$obj = (new SendStudentRequirement($TutorsbyCity,$data));
$this->dispatch($obj);

但它不作为后台运行，该函数正在等待队列完成，请帮帮我

默认情况下sync使用驱动程序。您应该将其更改为中列出的另一个驱动程序config/queue.php

在您的中查找以下行.env文件并调整为不同的驱动程序：

QUEUE_DRIVER=sync
