訪問CLI類中的參數

Question

如何從下面的類中的yml文件獲取參數，以便可以使用CLI打印它？

錯誤：

mbp:symfony em$ app/console phing:report 
PHP Fatal error: Call to undefined method Site\CommonBundle\Command\GreetCommand::getParameter() in symfony/src/Site/CommonBundle/Command/GreetCommand.php on line 25 

的symfony/src目錄/網站/ CommonBundle /命令/ GreetCommand.php

namespace Site\CommonBundle\Command; 

use Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand; 
use Symfony\Component\Console\Input\InputArgument; 
use Symfony\Component\Console\Input\InputInterface; 
use Symfony\Component\Console\Input\InputOption; 
use Symfony\Component\Console\Output\OutputInterface; 

class GreetCommand extends ContainerAwareCommand 
{ 
    public function __construct() 
    { 
     parent::__construct(); 
    } 

    protected function configure() 
    { 
     $this->setName('phing:report'); 
    } 

    protected function execute(InputInterface $input, OutputInterface $output) 
    { 
     $user = $this->getParameter('dummy_user'); 
     $output->writeln($user['admin']['username']); 
    } 
} 

的symfony /應用/配置/ globals_dev.yml

#Site globals 

parameters: 
    dummy_user: 
     admin: 
      username: admin 
     superadmin: 
      username: superadmin

如果您的目標是簡單地從容器中獲取參數，您可以從CLI像這樣訪問它：

$this->getContainer()->getParameter('dummy_user');
