当zend Framework 2中的邮件传输失败时，如何返回false？

Question

I am trying to return fail message with json if the mail sending is failed, here is my code:

$transport = new SmtpTransport();
            $options   = new SmtpOptions(array(
                    'name'              => 'localhost',
                    'host'              => 'localhost',
                    'connection_class'  => 'login',
                    'connection_config' => array(
                            'username' => 'cscsacsac',
                            'password' => 'csdca',
                            //'ssl'=>'ssl',
                            //'port' => '465',
                    ),
            ));

            $transport->setOptions($options);
            $sent = true;
            try {

                $transport->send($mail);
            }
            catch (\Zend\Mail\Transport\Exception\DomainException $e) {
                $sent = false;
            }

            if($sent){

                echo "success";

                exit;
            }

            elseif(!$sent){

                echo "fail";

                exit;
            }

and here is the ajax:

$.ajax({
          type: "POST",
          url: '<?php echo MAIN_URL?>cases',
          data: { name: name, email: email, mobile: mobile, address: address, compliant: compliant },
          success:function(data){

            if(data =='success'){

                $('.casesMailResponse').css({'color':'#00917D'});
                $('.casesMailResponse').html('Your case has been sent successfully.');
            }

            else if(data == 'fail'){

                $('.casesMailResponse').css({'color':'#F6565B'});
                $('.casesMailResponse').html('Some errors occurred, please try again.');
            }
          },
        });

but in case of failure I got Internal server error due to Incorrect authentication data , so the failure message is not displayed

Answer 1

You are catching only Zend\\Mail\\Transport\\Exception\\DomainException , but SMTP transport adapter can throw other exceptions too. For example in send method it can throw Zend\\Mail\\Transport\\Exception\\RuntimeException .

I suggest to catch exception interface of mail package:

    $sent = true;
    try {
        $transport->send($mail);
    } catch (\Zend\Mail\Transport\Exception\ExceptionInterface $e) {
        $sent = false;
    }

Answer 2

Could you try :

 }
 catch (\Zend\Mail\Transport\Exception\DomainException $e) {
    $sent = false;
 } catch (Exception $e) {
    $sent = false;
}

Just a guess....
