Guzzle 6中的GuzzleHttp \ Event \ SubscriberInterface相當於什麼？

Question

在狂飲5.3，你可以在下面的例子中使用event subscribers爲：

use GuzzleHttp\Event\EmitterInterface; 
use GuzzleHttp\Event\SubscriberInterface; 
use GuzzleHttp\Event\BeforeEvent; 
use GuzzleHttp\Event\CompleteEvent; 

class SimpleSubscriber implements SubscriberInterface 
{ 
    public function getEvents() 
    { 
     return [ 
      // Provide name and optional priority 
      'before' => ['onBefore', 100], 
      'complete' => ['onComplete'], 
      // You can pass a list of listeners with different priorities 
      'error' => [['beforeError', 'first'], ['afterError', 'last']] 
     ]; 
    } 

    public function onBefore(BeforeEvent $event, $name) 
    { 
     echo 'Before!'; 
    } 

    public function onComplete(CompleteEvent $event, $name) 
    { 
     echo 'Complete!'; 
    } 
} 

什麼是在狂飲6等價的例子嗎？

因爲我phpunit正在使用onBefore/onComplete和onError事件訂戶和文件需要升級的測試。

Answer 1

下面是示例代碼這相當於onBefore事件：

use Psr\Http\Message\RequestInterface; 

class SimpleSubscriber { 
    public function __invoke(RequestInterface $request, array $options) 
    { 
     echo 'Before!'; 
    } 
}
