我正在尝试根据此处给出的示例设置一个简单的事件订阅 - http://symfony.com/doc/master/components/event_dispatcher/introduction.html.

这是我的活动商店:

namespace CookBook\InheritanceBundle\Event;

final class EventStore
{
    const EVENT_SAMPLE = 'event.sample';
}

这是我的活动订阅者:

namespace CookBook\InheritanceBundle\Event;

use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\EventDispatcher\Event;

class Subscriber implements EventSubscriberInterface
{
    public static function getSubscribedEvents()
    {
        var_dump('here');
        return array(
                'event.sample' => array(
                        array('sampleMethod1', 10),
                        array('sampleMethod2', 5)
                ));
    }

    public function sampleMethod1(Event $event)
    {
        var_dump('Method 1');
    }

    public function sampleMethod2(Event $event)
    {
        var_dump('Method 2');
    }
}

这是services.yml中的配置:

kernel.subscriber.subscriber:
    class: CookBook\InheritanceBundle\Event\Subscriber
    tags:
        - {name:kernel.event_subscriber}

以下是我举办活动的方式:

use Symfony\Component\EventDispatcher\EventDispatcher;
use CookBook\InheritanceBundle\Event\EventStore;
$dispatcher = new EventDispatcher();
$dispatcher->dispatch(EventStore::EVENT_SAMPLE);

预期产量: …

我试图将关联数组作为参数传递给服务定义(确切地说是日光浴).但是,我收到以下错误:

"可捕获的致命错误:传递给Symfony\Component\DependencyInjection\Definition :: setArguments()的参数1必须是数组类型,字符串给定,"

我的services.yml内容如下:

parameters:
    mynamespace.api.solrclient.config: 
        endpoint:
            solrserver:
                host: "search.mysite.com"
                port: "80"
                path: "/solr/"

services:        
    mynamespace.api.solrclient:
        class: Solarium\Client
        arguments: "%mynamespace.api.solrclient.config%"

我定义参数数组的方式有什么明显错误吗？
