差不多两周前，我使用OneupUploaderBundle创建了有关上传的类似问题，但使用了FineUploader库。可悲的是，还没有答案。
与此同时，我尝试设置不同的上传库。
我正在Windows 10 Pro开发XAMPP [1]，其中包含PHP v7.0.8。
我正在使用Symfony v3.1.5，OneupUploaderBundle和Blueimp jQuery upload将文件上传到服务器。
在设置时我遵循了OneUpUploaderBundle [2]和jQuery file upload [3]，[4]的文档。
我想将文件上传到某个目录，然后检查他们的mime type并验证是允许上传的文件mime类型，之后 - 将它们移动到自定义目录（可以从文件更改为文件），最后我想要将文件路径和文件名保存到数据库。
文件上传工作正常，文件上传到oneup_uploader_endpoint('gallery')。即使是自定义文件Namer也可以上传到自定义目录。
但是，侦听器不会被调用（上传侦听器和验证）并显示在Symfony Profiler事件部分Not Called Listeners中！
这很不幸，因为我想使用Post_Persist事件将有关文件的信息保存到数据库。 OneupUploaderBundle events
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"]
我的自定义名称
<?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

services.yml，删除（我认为）现在不必要（重复 - 在OneupUploaderBundle中提供）验证，我在尝试使其工作时添加... 请告知。
感谢您的时间和知识。
答案 0 :(得分：3)
听听正确的事件。 事件交换包含映射的名称，以便您可以为此实现一个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出
oneup_uploader.post_upload.gallery
