php - 使用 Swiftmailer 捕获 block 异常不起作用

Question

我尝试了几种方法，但都没有用，包括 StackOverFlow -> Swiftmailer TransportException get uncaught by try catch block 中的一种.

我需要捕获可以在我的类中的 block 中生成的异常，该类运行类 Swiftmailer 的实例来发送电子邮件

 /**
 * @throws Be msut catch swiftmailer exception Swift_TransportException because ->setTo($send_to) containt '' (not valid email sender)
 * But not catch my code.
 */

 $transport = \Swift_SmtpTransport::newInstance()
            ->setHost($settings['smtp_host'])
            ->setPort($settings['smtp_port'])
            ->setEncryption($settings['smtp_security'])
            ->setUsername($settings['smtp_user'])
            ->setPassword($settings['smtp_pass']);
        $mailer = \Swift_Mailer::newInstance($transport);

    echo "Verify code\n";
    try {
        $message = \Swift_Message::newInstance()
            ->setSubject($subject)
            ->setFrom(array($settings['smtp_mail_sender'] => $settings['smtp_name_sender']))
            ->setTo($send_to)
            ->setBody($msg);
        $result = $mailer->send($message);
    } catch (\Swift_TransportException $Ste) {
        echo "EROORRRRRRRRRRRRRRRRRRRR\n\n\n";
    }

在控制台运行时显示错误

您将 try ... catch-block 包裹在您编写 swiftmailer 邮件的错误部分。

摘自 the manual :

If you add recipients automatically based on a data source that may contain invalid email addresses, you can prevent possible exceptions by validating the addresses using Swift_Validate::email($email) and only adding addresses that validate. Another way would be to wrap your setTo(), setCc() and setBcc() calls in a try-catch block and handle the Swift_RfcComplianceException in the catch block.

因此，您应该在将地址添加到您的 Swift_Message 对象时使用它，如下所示:

$message = Swift_Message::newInstance();

// add some message composing here...

$email = "somewrongadress.org";
try {
    $message->setTo(array($email));
} catch(Swift_RfcComplianceException $e) {
    echo "Address ".$email." seems invalid";
}

/* and now your transport... */
try {
    $result = $mailer->send($message);
} catch (\Swift_TransportException $Ste) {
    echo "EROORRRRRRRRRRRRRRRRRRRR\n\n\n";
}

That should do the job.
