Symfony dustin10/VichUploaderBundle事件

Question

我正在使用dustin10/VichUploaderBundle上傳圖像。

我正在使用Gregwar/ImageBundle調整圖像大小。

dustin10/VichUploaderBundle有一個POST_UPLOAD事件。我如何觸發該事件。我已閱讀文檔，但沒有說明如何觸發事件。

https://github.com/dustin10/VichUploaderBundle/blob/master/Event/Events.php

該計劃是在上傳後的ImageBundle來調整圖像。

你不能「觸發」的事件，它已經引發here：

/** 
    * Checks for file to upload. 
    * 
    * @param object $obj  The object. 
    * @param string $fieldName The name of the field containing the upload (has to be mapped). 
    */ 
    public function upload($obj, $fieldName) 
    { 
     $mapping = $this->getMapping($obj, $fieldName); 
     // nothing to upload 
     if (!$this->hasUploadedFile($obj, $mapping)) { 
      return; 
     } 
     $this->dispatch(Events::PRE_UPLOAD, new Event($obj, $mapping)); 
     $this->storage->upload($obj, $mapping); 
     $this->injector->injectFile($obj, $mapping); 
     $this->dispatch(Events::POST_UPLOAD, new Event($obj, $mapping)); 
    } 

你可以做的是手柄的事件，這是我想你指至。你可以通過創建一個監聽器來做到這一點，如概述here。監聽器將監聽POST_UPLOAD事件，像這樣：

# app/config/services.yml 
services: 
    app_bundle.listener.uploaded_file_listener: 
     class: AppBundle\EventListener\UploadedFileListener 
     tags: 
      - { name: kernel.event_listener, event: vich_uploader.post_upload, method: onPostUpload } 

監聽器類將typehint像下面的VICH上傳事件：

// src/AppBundle/EventListener/AcmeRequestListener.php 
namespace AppBundle\EventListener; 

use Symfony\Component\HttpKernel\HttpKernel; 
use Vich\UploaderBundle\Event\Event; 

class UploadedFileListener 
{ 
    public function onPostUpload(Event $event) 
    { 
     $uploadedFile = $event->getObject(); 
     // your custom logic here 
    } 
}
