在symfony2中记录swiftmailer send()活动 [英] Logging swiftmailer send() activity in symfony2

问题描述

我正在使用swiftmailer从我的symfony2.2项目发送邮件.有没有一种方法可以全局记录所有电子邮件信息并发送结果?

Im using swiftmailer for sending mails from my symfony2.2 project. Is there a way to log globally all email info and send results?

如果mailer send()方法具有触发somę事件，那就太好了，但是我看不到.

It would be great if mailer send() method have trigger somę event, but I can't see it does.

推荐答案

我是这样做的:

# /src/Tiriana/MyBundle/Resources/config/services.yml
parameters:
     swiftmailer.class:  Tiriana\MyBundle\Util\MailerWrapper

2.邮件包装服务

它扩展了Swift_Mailer，因为它被传递给不同的类，期望邮件程序是Swift_Mailer的实例. 并创建Swift_Mailer实例作为字段，因为... $transport在\Swith_Mailer中是private(

2. Mailer wraper service

It extends Swift_Mailer, because it is passed to different classes expecting mailer to be instance of Swift_Mailer. And it creates Swift_Mailer instance as a field, because... $transport is private in \Swith_Mailer (link). Code would be so much better if $transport was protected...

// /src/Tiriana/MyBundle/Util/MailerWrapper.php
namespace Tiriana\MyBundle\Util;

use Monolog\Logger;
use Monolog\Handler\StreamHandler;

class MailerWrapper extends \Swift_Mailer
{
    private $_logger;

    /** @var \Swift_Mailer */
    private $_mailer;

    public function send(\Swift_Mime_Message $message, &$failedRecipients = null)
    {
        $this->_log('BEFORE SEND');  // <-- add your logic here
        $ret = $this->_mailer->send($message, $failedRecipients);
        $this->_log('AFTER SEND');  // <-- add your logic here

        return $ret;
    }

    /** @return Logger */
    public function getLogger()
    {
        return $this->_logger;
    }

    protected function _log($msg)
    {
        $this->getLogger()->debug(__CLASS__ . ": " . $msg);
    }

    public function __construct(\Swift_Transport $transport, Logger $logger)
    {
        /* we need _mailer because _transport is private
           (not protected) in Swift_Mailer, unfortunately... */
        $this->_mailer = parent::newInstance($transport);
        $this->_logger = $logger;
    }

    public static function newInstance(\Swift_Transport $transport)
    {
        return new self($transport);
    }

    public function getTransport()
    {
        return $this->_mailer->getTransport();
    }

    public function registerPlugin(Swift_Events_EventListener $plugin)
    {
        $this->getTransport()->registerPlugin($plugin);
    }
}

3.捆绑生成器

// /src/Tiriana/MyBundle/TirianaMyBundle.php
namespace Tiriana\MyBundle;

use Symfony\Component\HttpKernel\Bundle\Bundle;
use Symfony\Component\DependencyInjection\ContainerBuilder;

use Tiriana\MyBundle\DependencyInjection\Compiler\OverrideServiceSwiftMailer;

class TirianaMyBundle extends Bundle
{
    public function build(ContainerBuilder $container)
    {
        parent::build($container);
        $container->addCompilerPass(new OverrideServiceSwiftMailer());  // <-- ADD THIS LINE
    }
}

4.还有OverrideServiceSwiftMailer类

// /src/Tiriana/MyBundle/DependencyInjection/Compiler/OverrideServiceSwiftMailer.php
namespace Tiriana\MyBundle\DependencyInjection\Compiler;
use Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Reference;

class OverrideServiceSwiftMailer implements CompilerPassInterface
{
    public function process(ContainerBuilder $container)
    {
        /* @var $definition \Symfony\Component\DependencyInjection\DefinitionDecorator */
        $definition = $container->findDefinition('mailer');
        $definition->addArgument(new Reference('logger'));
        /* add more dependencies if you need - i.e. event_dispatcher */
    }
}
