我正在尝试从我的GOOGLE Apps域发送电子邮件.大多数时间都会发送电子邮件,但有时会抛出此异常并且不会发送电子邮件.

Uncaught PHP Exception Swift_TransportException: "Expected response code 220 but got code "",wITh message """ at C:\HostingSpaces\abc\domain.COM\wwwroot\vendor\swiftmailer\swiftmailer\lib\classes\Swift\Transport\AbstractSmtpTransport.PHP line 383 {"exception":"[object] (Swift_TransportException(code: 0): ExPEcted response code 220 but got code \"\",with message \"\" at C:\\HostingSpaces\\abc\\domain.com\\wwwroot\\vendor\\swiftmailer\\swiftmailer\\lib\\classes\\Swift\\Transport\\AbstractSmtpTransport.PHP:383)"} []

是的,我使用SSL,是的,我已经允许访问不太安全的应用程序,是的我使用端口465.我已启用假脱机,以便应用程序不会崩溃,因为异常不会被捕获.

我的config.yML如下

swiftmailer:
    transport:  smtp
    host:       smtp.gmail.com
    username:   no-reply@googledomain.com
    password:   password
    port:       465
    encryption: ssl
    spool: { type: memory }

我的电子邮件课程如下

public function send_new_order_email($entity) {
    try{
        $message = $this->getEmailObj("toaddress@gmail.com");
        $message->setBody(
                $this->renderView(
                    'APIBundle:Emails:ops_neworder.html.twig',array('entity' => $entity)
                ),'text/html'
            )->setSubject('New Order : '.$entity->getId());

        $this->container->get('mailer')->send($message);
    }
    catch(Exception $e){}
}

PRivate function getEmailObj($email){
    $message = \Swift_Message::newInstance()
            ->setFrom('no-reply@googledomain.com')
            ->setTo($email);
    return $message;
}

你对这项工作有什么建议吗？
