发送从cron任务电子邮件symfony的

Question

我试图发送邮件使用与Symfony的后台任务的邮件，所以我的问题是如何将我执行与我的执行功能使用swiftmailer我的命令？在此先感谢

我想要的swiftmailer是在我的执行方法，这样我就可以根据后台任务

    $mail = \Swift_Message::newInstance(); 
        $mail->setFrom('from@example.com') 
         ->setTo('to@example.com') 
         ->setSubject('Email subject') 
         ->setBody('email body, can be swift template') 

        $this->get('mailer')->send($mail); 

我CronTasksRunCommand

protected function execute(InputInterface $input, OutputInterface $output) 
{ 
    $output->writeln('<comment>Running Cron Tasks...</comment>'); 

    $this->output = $output; 
    $em = $this->getContainer()->get('doctrine.orm.entity_manager'); 
    $crontasks = $em->getRepository('AppBundle:CronTask')->findAll(); 

    foreach ($crontasks as $crontask) { 
     // Get the last run time of this task, and calculate when it should run next 
     $lastrun = $crontask->getLastRun() ? $crontask->getLastRun()->format('U') : 0; 
     $nextrun = $lastrun + $crontask->getInterval(); 

     // We must run this task if: 
     // * time() is larger or equal to $nextrun 
     $run = (time() >= $nextrun); 

     if ($run) { 
      $output->writeln(sprintf('Running Cron Task <info>%s</info>', $crontask)); 

      // Set $lastrun for this crontask 
      $crontask->setLastRun(new \DateTime()); 

      try { 
       $commands = $crontask->getCommands(); 
       foreach ($commands as $command) { 
        $output->writeln(sprintf('Executing command <comment>%s</comment>...', $command)); 

        // Run the command 
        $this->runCommand($command); 
       } 

       $output->writeln('<info>SUCCESS</info>'); 
      } catch (\Exception $e) { 
       $output->writeln('<error>ERROR</error>'); 
      } 

      // Persist crontask 
      $em->persist($crontask); 
     } else { 
      $output->writeln(sprintf('Skipping Cron Task <info>%s</info>', $crontask)); 
     } 
    } 

    // Flush database changes 
    $em->flush(); 

    $output->writeln('<comment>Done!</comment>'); 
}

发送电子邮件如果您的命令类扩展ContainerAware Command类，然后只需更换

$this->get('mailer')->send($mail); 

与

$this->getContainer()->get('mailer')->send($mail);
