Swiftmailer捕获块异常不起作用

Question

我尝试了几种方法，但是没有一种方法可行，包括StackOverFlow-> Swiftmailer TransportException中的一种方法被try catch块捕获了。

我需要捕获运行类Swiftmailer的实例以发送电子邮件的类的块中可能生成的异常

 /**
 * @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";
    }

在控制台上运行时显示错误

Answer 1

您将try ... catch-block包裹在swiftmailer邮件撰写的错误部分周围。

手册摘录：

如果您基于可能包含无效电子邮件地址的数据源自动添加收件人，则可以通过使用Swift_Validate::email($email)并仅添加经过验证的地址来验证地址，从而防止可能的例外情况。另一种方法是将，包装起来 setTo()，setCc()并setBcc()在try-catch块中调用并在catch块中处理Swift_RfcComplianceException。

因此，在向Swift_Message-object 添加地址时应使用它，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.
