介绍
大约两周前，我使用OneupUploaderBundle创建了有关上载的类似问题，但使用了FineUploader库。不幸的是，目前还没有答案。
同时，我尝试设置其他上传库。
我正在使用Windows 10 Pro [1](其中包括XAMPP)在PHP v7.0.8上进行开发。
我正在使用Symfony v3.1.5，OneupUploaderBundle和Blueimp jQuery upload来将文件上传到服务器。
在进行设置时，我遵循了
OneUpUploaderBundle [2]和jQuery file upload [3]，[4]的文档。问题
我想将文件上传到某个目录，然后检查其mime type并验证是否允许上传文件mime类型，然后将其移动到自定义目录(可以在文件之间更改)，最后我想保留文件路径和文件数据库名称。
文件上传正常，文件上传到
oneup_uploader_endpoint('gallery')。甚至自定义文件Namer都可以工作，并允许上传到自定义目录。但是，监听器不称为(上传监听器和验证)，而是显示在Symfony Profiler事件部分的
Not Called Listeners中!不幸的是，我想使用
Post_Persist事件将有关文件的信息保存到数据库。 OneupUploaderBundle events。代码
我的services.yml
services:
app.upload_listener:
class: AppBundle\EventListener\UploadListener
arguments: ["@doctrine.orm.entity_manager"]
tags:
- { name: kernel.event_listener, event: oneup_uploader.post_persist.default_uploader, method: onUpload }
- { name: kernel.event_listener, event: oneup_uploader.post_persist.default_uploader, method: onPostUpload }
app.upload_unique_namer:
class: AppBundle\Uploader\Naming\UploadUniqueNamer
arguments: ["@session"]
我的自定义命名器
<?php
namespace AppBundle\Uploader\Naming;
use Oneup\UploaderBundle\Uploader\File\FileInterface;
use Oneup\UploaderBundle\Uploader\Naming\NamerInterface;
use Symfony\Component\HttpFoundation\Session\Session;
class UploadUniqueNamer implements NamerInterface
{
private $session;
public function __construct(Session $session)
{
$this->session = $session;
}
/**
* Creates a user directory name for the file being uploaded.
*
* @param FileInterface $file
* @return string The directory name.
*/
public function name(FileInterface $file)
{
$upload_files_path = $this->session->get('upload_files_path');
$unique_name = uniqid();
return sprintf('%s/%s_%s',
$upload_files_path,
$unique_name,
$file->getClientOriginalName()
);
}
}
我的config.yml
oneup_uploader:
mappings:
gallery:
frontend: blueimp
enable_progress: true
namer: app.upload_unique_namer
use_orphanage: false
allowed_mimetypes: [image/png, image/jpg, image/jpeg, image/gif]
max_size: 200M
我的上传监听器:
<?php
namespace AppBundle\EventListener;
use Oneup\UploaderBundle\Event\PreUploadEvent;
use Oneup\UploaderBundle\Event\PostUploadEvent;
use Oneup\UploaderBundle\Event\PostPersistEvent;
use Doctrine\ORM\EntityManager;
use AppBundle\Entity\Product;
class UploadListener
{
/**
* @var EntityManager
*/
private $entityManager;
//protected $originalName;
public function __construct(EntityManager $entityManager)
{
$this->entityManager = $entityManager;
}
public function onUpload(PostPersistEvent $event)
{
$file = $event->getFile();
$this->originalName = $file->getClientOriginalName();
}
public function onPostUpload(PostPersistEvent $event)
{
$file = $event->getFile();
$object = new Product();
$object->setName($file->getClientOriginalName());
//$object->setName($file->getPathName());
$this->entityManager->persist($object);
$this->entityManager->flush();
}

更新
services.yml，删除了(我认为)，现在不再需要(重复-在OneupUploaderBundle中提供)，我在尝试使其生效时添加了该验证...结论
请指教。
感谢您的时间和知识。
最佳答案
只是听正确的事件。
事件交换包含映射的名称，以便您可以对此映射实现一种不会影响其他逻辑的特定逻辑。
此格式的事件。
oneup_uploader.post_upload.{mapping}
在你的情况下，它会给
oneup_uploader.post_upload.gallery
