php – 在symfony2中记录swiftmailer send()活动

我使用 swiftmailer从我的symfony2.2项目发送邮件.有没有办法在全球范围内记录所有电子邮件信息并发送结果？

如果mailer send()方法具有触发somę事件,那将是很好的,但我看不到它.

服务：

class MessageFileLogger implements Swift_Events_SendListener
{
    private $filename;

    public function __construct($filename)
    {
        $this->filename = $filename;
    }

    public function getMessages()
    {
        return $this->read();
    }

    public function clear()
    {
        $this->write(array());
    }

    public function beforeSendPerformed(Swift_Events_SendEvent $evt)
    {
        $messages = $this->read();
        $messages[] = clone $evt->getMessage();

        $this->write($messages);
    }

    public function sendPerformed(Swift_Events_SendEvent $evt)
    {
    }

    private function read()
    {
        if (!file_exists($this->filename)) {
            return array();
        }

        return (array) unserialize(file_get_contents($this->filename));
    }

    private function write(array $messages)
    {
        file_put_contents($this->filename,serialize($messages));
    }
}

配置：

services:
    umpirsky.mailer.message_file_logger:
        class: MessageFileLogger
        arguments:
            - %kernel.logs_dir%/mailer.log
        tags:
            - { name: swiftmailer.plugin }
