如何使用Gaufrette和Symfony 3.0 [英] How to Use Gaufrette and Symfony 3.0
问题描述
弄清楚如何将Symfony 3.0与Gaufete一起使用以便上传到s3存储桶中，我遇到了一个问题.
I have an issue from figuring out how to use the Symfony 3.0 with Gaufete in order to Upload into an s3 bucket.
根据文档: https://github.com/KnpLabs/KnpGaufretteBundle
我已经设置了config.yml:
I have set the config.yml:
knp_gaufrette:
adapters:
photostorage:
amazon_s3:
amazon_s3_id: amazonS3
bucket_name: '%save_location%'
options:
directory: 'symphotest'
和services.yml:
And the services.yml:
services:
amazonS3:
class: Aws\S3\S3Client
factory_class: Aws\S3\S3Client
factory_method: 'factory'
arguments:
key: %amazon_s3.key%
secret: %amazon_s3.secret%
region: %amazon_s3.region%
由于我想使用自定义环境变量进行任何配置，因此我将其传递给文件params.php:
And because I want to use custom enviromental variables any sort of configuration I pass it a file params.php:
$container->setParameter('save_type','s3');
$container->setParameter('save_location',getenv('BUCKET'));
$container->setParameter('aws_key',getenv('S3_ACCESS'));
$container->setParameter('aws_secret_key',getenv('S3_SECRET'));
我将其包含在config.yml顶部的位置:
Where I Include it on the top of the config.yml:
imports:
- { resource: params.php }
- { resource: security.yml }
- { resource: services.yml }
我已将实体名称命名为Images.php:
I have made an Entity names Images.php:
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use Symfony\Component\Validator\Constraints as Assert;
use Gaufrette\Adapter\AwsS3 as AwsS3Adapter;
use Gaufrette\Filesystem;
/**
* @ORM\Entity
* @ORM\Table(name="images")
* @ORM\HasLifecycleCallbacks
*/
class Images
{
/**
* @ORM\Column(type="string", length=60)
* @ORM\Id
* @ORM\GeneratedValue(strategy="CUSTOM")
* @ORM\CustomIdGenerator(class="AppBundle\Doctrine\AutoIdGenerate")
*/
private $id;
/**
* @ORM\Column(type="string", length=100)
*/
private $name;
/**
* @ORM\Column(type="string", length=100)
*/
private $name_small;
/**
* @ORM\ManyToOne(targetEntity="AppBundle\Entity\ImageGroups", inversedBy="images")
*/
private $users;
/**
* @Assert\File(maxSize="6000000")
*/
private $file;
private $tmp;
private $path;
public function getFile()
{
return $file;
}
public function setFile(UploadedFile $file = null)
{
$this->file=$file;
};
public function __construct()
{
//IDK what to do here
}
/**
* @ORM\PrePersist()
* @ORM\PreUpdate()
*/
public function preUpload()
{
if (null !== $this->getFile())
{
$filename = sha1(uniqid(gethostname(), true));
$this->name = $filename.'.'.$this->getFile()->guessExtension();
$this->$name_small='small'.$filename.'.'.$this->getFile()->guessExtension();
}
}
/**
* @ORM\PostPersist()
* @ORM\PostUpdate()
*/
public function upload()
{
if (null === $this->getFile())
{
return;
}
// if there is an error when moving the file, an exception will
// be automatically thrown by move(). This will properly prevent
// the entity from being persisted to the database on error
$this->getFile()->move($this->getUploadRootDir(), $this->path);
// check if we have an old image
if (isset($this->temp))
{
// delete the old image
unlink($this->getUploadRootDir().'/'.$this->temp);
// clear the temp image path
$this->temp = null;
}
$this->file = null;
}
/**
* @ORM\PostRemove()
*/
public function removeUpload()
{
$file = $this->getAbsolutePath();
if ($file)
{
//Do stuff for Deleting
}
}
/**
* Get id
*
* @return string
*/
public function getId()
{
return $this->id;
}
/**
* Get name
*
* @return string
*/
public function getName()
{
return $this->name;
}
/**
* Get nameSmall
*
* @return string
*/
public function getNameSmall()
{
return $this->name_small;
}
}
But I do not know how can I get the S3 Adapter and client because in this example:https://github.com/KnpLabs/Gaufrette/blob/master/doc/adapters/awsS3.md
In启动s3客户端和文件系统.但是在Symfony 3.0上，我已经在config.yml上配置了它们.因此，必须有另一种方法来获取它们.
In initiates the s3 client and filesystem. But on Symfony 3.0 I've already configured them on config.yml. Therefore there must be another way to get them.
我只想举一个用法的例子.
All I want is an example of usage.
推荐答案
请勿将服务注入实体:这是一种不好的做法.
Don't inject a service into an entity: it is bad practice.
改为使用Doctrine事件订阅者:如中所述Symfony文档
Use Doctrine event subscribers instead: as described on Symfony docs
# app/config/services.yml
services:
# ...
AppBundle\EventListener\SearchIndexerSubscriber:
tags:
- { name: doctrine.event_subscriber }
事件订阅者:
// src/AppBundle/EventListener/SearchIndexerSubscriber.php
namespace AppBundle\EventListener;
use AppBundle\Entity\Product;
use Doctrine\Common\EventSubscriber;
// for Doctrine < 2.4: use Doctrine\ORM\Event\LifecycleEventArgs;
use Doctrine\Common\Persistence\Event\LifecycleEventArgs;
use Doctrine\ORM\Events;
class SearchIndexerSubscriber implements EventSubscriber
{
public function getSubscribedEvents()
{
return [
Events::postPersist,
Events::postUpdate,
];
}
public function postUpdate(LifecycleEventArgs $args)
{
$this->index($args);
}
public function postPersist(LifecycleEventArgs $args)
{
$this->index($args);
}
public function index(LifecycleEventArgs $args)
{
$entity = $args->getObject();
// perhaps you only want to act on some "Product" entity
if ($entity instanceof Product) {
$entityManager = $args->getObjectManager();
// ... do something with the Product
}
}
}
