不调用 Symfony 3.1 和 OneUploaderBundle + Blueimp = UploadListen

Question

简介

大约两周前，我创建了关于使用 OneupUploaderBundle 上传的类似问题，但使用 FineUploader 库。可悲的是，目前还没有答案。与此同时，我尝试设置不同的上传库。

我正在与XAMPP [1] 进行Windows 10 Pro开发，其中包括PHP v7.0.8 .

• [1] XAMPP for Windows

我正在使用Symfony v3.1.5，OneupUploaderBundle和Blueimp jQuery上传，以便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。

• [2] OneupUploaderBundle 文档
• [3] OneupUploaderBundle Blueimp 示例
• [4] Blueimp jQuery 文件上传文档

问题

我想将文件上传到某个目录，然后检查它们的 mime 类型并验证是否允许上传文件 mime 类型，然后 - 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')。甚至自定义文件Namer也可以工作，并允许上传到自定义目录。

但是，侦听器不会被调用（上传侦听器和验证），并显示在Symfony Profiler Events部分Not Called Listeners！

这很不幸，因为我想使用事件将有关文件的信息保存到数据库Post_Persist。OneupUploaderBundle 事件。

法典

我的服务.yml

services:
    app.upload_listener:
        class: AppBundleEventListenerUploadListener
        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: AppBundleUploaderNamingUploadUniqueNamer
        arguments: ["@session"]

我的自定义命名器

<?php
namespace AppBundleUploaderNaming;
use OneupUploaderBundleUploaderFileFileInterface;
use OneupUploaderBundleUploaderNamingNamerInterface;
use SymfonyComponentHttpFoundationSessionSession;
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()
        );
    }
}

我的配置.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 AppBundleEventListener;
use OneupUploaderBundleEventPreUploadEvent;
use OneupUploaderBundleEventPostUploadEvent;
use OneupUploaderBundleEventPostPersistEvent;
use DoctrineORMEntityManager;
use AppBundleEntityProduct;
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

1. 添加了有关开发环境的说明。
2. 尝试了与Symfony v2.8.8相同的代码，遗憾的是没有调用UploadListener。
3. 编辑services.yml，删除（我认为）现在不必要的（重复 - 在 OneupUploaderBundle 中提供）我在尝试使其工作时添加的验证......

结论

请指教。

感谢您的时间和知识。

只需聆听正确的事件。事件交换包含映射的名称，以便您可以对此映射实现不会影响其他映射的特定逻辑。

此格式的事件。

oneup_uploader.post_upload.{mapping}

在您的情况下，它会给

oneup_uploader.post_upload.gallery
