Symfony 信使：消费不起作用（无异常）

Question

Symfony 5.1

我正在尝试为我的项目设置一个异步 email 处理程序。 电子邮件被发送到 Doctrine messenger_messages 表，但是当我使用命令php bin/console messenger:consume -vv时，我有[OK] Consuming messages from transports "async". 控制台中的消息，但表中没有消息被传递。

编辑：昨天有效，今天再次尝试时无效。 我在消费者运行时重新启动了我的服务器，并且在错误消息中：

An exception occurred while executing 'SELECT m.* FROM messenger_messages m WHERE (m.delivered_at is null
  OR m.delivered_at < ?) AND (m.available_at <= ?) AND (m.queue_name = ?) ORDER BY available_at ASC LIMIT 1
  FOR UPDATE' with params ["2020-07-16 07:20:55", "2020-07-16 08:20:55", "default"]:

  SQLSTATE[HY000]: General error: 2006 MySQL server has gone away

我看到消费者检查'available_at <= 2020-07-16 08:20:55'，而我表中的旧消息是available_at 2020-07-16 09:33:30。 我不知道如何改变它。

Edit2：看起来我有一个时区问题：我的时区是 UTC+2，现在是 10:36，但是在 dev.log 中，消费者正在请求 08:36：

[2020-07-16T08:36:44.241767+00:00] doctrine.DEBUG: "COMMIT" [] []
[2020-07-16T08:36:45.242051+00:00] doctrine.DEBUG: "START TRANSACTION" [] []
[2020-07-16T08:36:45.242341+00:00] doctrine.DEBUG: SELECT m.* FROM messenger_messages m WHERE (m.delivered_at is null OR m.delivered_at < ?) AND (m.available_at <= ?) AND (m.queue_name = ?) ORDER BY available_at ASC LIMIT 1 FOR UPDATE ["2020-07-16T07:36:45+00:00","2020-07-16T08:36:45+00:00","default"] []

Edit3：我的问题出在 CLI 使用的 php.ini 中。 我已经在 Symfony 使用的 php.ini 中定义了我的时区，但没有在 CLI 中定义，所以由于消费者是从控制台运行的，所以它是在 UTC 而不是 UTC+2。

我的电子邮件处理程序：

class EmailHandler implements MessageHandlerInterface
{
    private $address;
    private $mailer;

    public function __construct($address, MailerInterface $mailer)
    {
        $this->mailer = $mailer;
        $this->address = $address;
    }
    public function __invoke(Email $email)
    {
        $user =  $email->getTask()->getIdUser();
        $token = $user->getToken();
        $email = (new TemplatedEmail())
            ->from($this->address)
            ->to($user->getEmail())
            ->subject('Activation de compte Classe Virtuelle')
            ->htmlTemplate('emails/activate.html.twig')
            ->context([
                'address' => $user->getEmail(),
                'nom' => $email->getTask()->getNom(),
                'prenom' => $email->getTask()->getPrenom(),
                'token' => $token
            ]);
            $this->mailer->send($email);
    }

我的 Email：

class Email
{
    private $task;

    /**
     * @return mixed
     */
    public function getTask()
    {
        return $this->task;
    }

    /**
     * @param mixed $task
     */
    public function setTask($task): void
    {
        $this->task = $task;
    }
}

信使.yaml

    framework:
    messenger:
        # Uncomment this (and the failed transport below) to send failed messages to this transport for later handling.
        # failure_transport: failed

        transports:
            # https://symfony.com/doc/current/messenger.html#transport-configuration
            async: '%env(MESSENGER_TRANSPORT_DSN)%'
            # failed: 'doctrine://default?queue_name=failed'
            # sync: 'sync://'

        routing:
            # Route your messages to the transports
            'App\Controller\Message\Email': async

.env

MESSENGER_TRANSPORT_DSN=doctrine://default

我的 controller

            $email = new Email();
            $email->setTask($addUser);
            $messageBus->dispatch($email);

当我在我的 controller 中发送 email 时，在我的表中添加了一行

100,
"O:36:\""Symfony\\Component\\Messenger\\Envelope\"":2:{s:44:\""\0Symfony\\Component\\Messenger\\Envelope\0stamps\"";a:1:{s:46:\""Symfony\\Component\\Messenger\\Stamp\\BusNameStamp\"";a:1:{i:0;O:46:\""Symfony\\Component\\Messenger\\Stamp\\BusNameStamp\"":1:{s:55:\""\0Symfony\\Component\\Messenger\\Stamp\\BusNameStamp\0busName\"";s:21:\""messenger.bus.default\"";}}}s:45:\""\0Symfony\\Component\\Messenger\\Envelope\0message\"";O:28:\""App\\Controller\\Message\\Email\"":1:{s:34:\""\0App\\Controller\\Message\\Email\0task\"";O:17:\""App\\Entity\\Eleves\"":7:{s:21:\""\0App\\Entity\\Eleves\0id\"";N;s:26:\""\0App\\Entity\\Eleves\0id_user\"";O:16:\""App\\Entity\\Users\"":12:{s:20:\""\0App\\Entity\\Users\0id\"";N;s:29:\""\0App\\Entity\\Users\0identifiant\"";s:40:\""200c6d84e5eeeec42b1c7ea1ff2945340013f5db\"";s:21:\""\0App\\Entity\\Users\0mdp\"";s:40:\""f0f1b73b43acb236eb1388bd781189209361b8b2\"";s:23:\""\0App\\Entity\\Users\0email\"";s:20:\""zedzdezde@zedzde.zed\"";s:25:\""\0App\\Entity\\Users\0id_role\"";O:16:\""App\\Entity\\Roles\"":3:{s:20:\""\0App\\Entity\\Roles\0id\"";i:1;s:26:\""\0App\\Entity\\Roles\0nom_role\"";s:10:\""ROLE_ELEVE\"";s:23:\""\0App\\Entity\\Roles\0users\"";O:33:\""Doctrine\\ORM\\PersistentCollection\"":2:{s:13:\""\0*\0collection\"";O:43:\""Doctrine\\Common\\Collections\\ArrayCollection\"":1:{s:53:\""\0Doctrine\\Common\\Collections\\ArrayCollection\0elements\"";a:0:{}}s:14:\""\0*\0initialized\"";b:0;}}s:40:\""\0App\\Entity\\Users\0commentaires_concernes\"";O:43:\""Doctrine\\Common\\Collections\\ArrayCollection\"":1:{s:53:\""\0Doctrine\\Common\\Collections\\ArrayCollection\0elements\"";a:0:{}}s:37:\""\0App\\Entity\\Users\0commentaires_ecrits\"";O:43:\""Doctrine\\Common\\Collections\\ArrayCollection\"":1:{s:53:\""\0Doctrine\\Common\\Collections\\ArrayCollection\0elements\"";a:0:{}}s:29:\""\0App\\Entity\\Users\0sousgroupes\"";O:43:\""Doctrine\\Common\\Collections\\ArrayCollection\"":1:{s:53:\""\0Doctrine\\Common\\Collections\\ArrayCollection\0elements\"";a:0:{}}s:23:\""\0App\\Entity\\Users\0actif\"";i:0;s:24:\""\0App\\Entity\\Users\0admins\"";N;s:38:\""\0App\\Entity\\Users\0sousgroupes_visibles\"";O:43:\""Doctrine\\Common\\Collections\\ArrayCollection\"":1:{s:53:\""\0Doctrine\\Common\\Collections\\ArrayCollection\0elements\"";a:0:{}}s:23:\""\0App\\Entity\\Users\0token\"";s:40:\""f3ab58732b9bf1029f3105f65d2469fd955e61b6\"";}s:22:\""\0App\\Entity\\Eleves\0nom\"";s:7:\""aezdzed\"";s:25:\""\0App\\Entity\\Eleves\0prenom\"";s:9:\""zedzdezed\"";s:28:\""\0App\\Entity\\Eleves\0id_classe\"";O:18:\""App\\Entity\\Classes\"":6:{s:22:\""\0App\\Entity\\Classes\0id\"";i:1;s:30:\""\0App\\Entity\\Classes\0nom_classe\"";s:5:\""2nde1\"";s:26:\""\0App\\Entity\\Classes\0eleves\"";O:33:\""Doctrine\\ORM\\PersistentCollection\"":2:{s:13:\""\0*\0collection\"";O:43:\""Doctrine\\Common\\Collections\\ArrayCollection\"":1:{s:53:\""\0Doctrine\\Common\\Collections\\ArrayCollection\0elements\"";a:0:{}}s:14:\""\0*\0initialized\"";b:0;}s:25:\""\0App\\Entity\\Classes\0cours\"";O:33:\""Doctrine\\ORM\\PersistentCollection\"":2:{s:13:\""\0*\0collection\"";O:43:\""Doctrine\\Common\\Collections\\ArrayCollection\"":1:{s:53:\""\0Doctrine\\Common\\Collections\\ArrayCollection\0elements\"";a:0:{}}s:14:\""\0*\0initialized\"";b:0;}s:28:\""\0App\\Entity\\Classes\0archives\"";O:33:\""Doctrine\\ORM\\PersistentCollection\"":2:{s:13:\""\0*\0collection\"";O:43:\""Doctrine\\Common\\Collections\\ArrayCollection\"":1:{s:53:\""\0Doctrine\\Common\\Collections\\ArrayCollection\0elements\"";a:0:{}}s:14:\""\0*\0initialized\"";b:0;}s:25:\""\0App\\Entity\\Classes\0profs\"";O:33:\""Doctrine\\ORM\\PersistentCollection\"":2:{s:13:\""\0*\0collection\"";O:43:\""Doctrine\\Common\\Collections\\ArrayCollection\"":1:{s:53:\""\0Doctrine\\Common\\Collections\\ArrayCollection\0elements\"";a:0:{}}s:14:\""\0*\0initialized\"";b:0;}}s:32:\""\0App\\Entity\\Eleves\0id_sousgroupe\"";O:43:\""Doctrine\\Common\\Collections\\ArrayCollection\"":1:{s:53:\""\0Doctrine\\Common\\Collections\\ArrayCollection\0elements\"";a:0:{}}s:23:\""\0App\\Entity\\Eleves\0type\"";s:6:\""Eleves\"";}}}",

检查您是否在 php.ini 中配置了正确的时区。 工作人员通过 created_at 和 available_at db 列选择并执行排队的任务。 正如我在您提供的日志数据中看到的，您的 PHP 时区设置为 UTC，这可能不是有意的。

日志：

[2020-07-16T08:36:45.242341+00:00] doctrine.DEBUG: SELECT m.* FROM messenger_messages m WHERE (m.delivered_at is null OR m.delivered_at < ?) AND (m.available_at <= ?) AND (m.queue_name = ?) ORDER BY available_at ASC LIMIT 1 FOR UPDATE ["2020-07-16T07:36:45+00:00","2020-07-16T08:36:45+00:00","default"] []

D b：

2020-07-15 16:05:25,
2020-07-15 16:05:25,

如您所见，消息在 7:30 小时后排队。

在https://www.php.net/manual/en/timezones.php中的 php.ini 中设置正确的时区并重新启动服务。

如果您不知道 php.ini 位于何处，请运行以下命令：

php -i | grep php.ini
