如何在symfony中收听控制台事件？

我试图用symfony标准版（2.3）连接symfony控制台事件，但它就是不起作用

我根据他们的想法创建了一个侦听器，并遵循以下步骤：

但是很明显，标签是不正确的，我找不到正确的名字。我该怎么做呢？

所以，我终于得到了它。原始帖子中的上述代码完全有效，但我在bundle中定义了my services.yml，而不是在application config

app/config.yml

中。这意味着从未加载配置。我必须通过容器扩展导入配置：

# Acme/DemoBundle/DependencyInjection/AcmeDemoExtension.php
namespace Acme\DemoBundle\DependencyInjection;

use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\Loader;

class AcmeDemoExtension extends Extension
{
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = new Configuration();
        $config = $this->processConfiguration($configuration, $configs);

        $loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
        $loader->load('services.yml');
    }
}

及

虽然我想你甚至可以省略

$configuration=newconfiguration（）部分和
配置
类。
您的
标记
事件侦听器名称必须是
控制台。事件侦听器
。它帮助我解决了这个问题

services:
    kernel.listener.command_dispatch:
        class: Acme\DemoBundle\EventListener\AcmeCommandListener
        tags:
            - { name: console.event_listener, event: console.command }

Platform\EventListener\Console\InitListener:
标签：
-{name:kernel.event_侦听器，事件：console.command，优先级：1024}
您使用的是
php应用程序/console
还是自定义应用程序？我使用的是Symfony标准版，希望在执行
app/console
命令之前添加事件触发。我已经在symfony google小组中询问过了，有人说我需要使用一个服务来配置它（正如我在上面尝试的那样）。谢谢你的标签
