我在弄清楚如何将 Symfony 3.0 与 Gaufete 一起使用以上传到 s3 存储桶时遇到了问题。
根据文档:https ://github.com/KnpLabs/KnpGaufretteBundle
我已经设置了 config.yml:
knp_gaufrette:
adapters:
photostorage:
amazon_s3:
amazon_s3_id: amazonS3
bucket_name: '%save_location%'
options:
directory: 'symphotest'
和 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%
因为我想使用任何类型的配置自定义环境变量,所以我将它传递给一个文件 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'));
我将它包含在 config.yml 顶部的位置:
imports:
- { resource: params.php }
- { resource: security.yml }
- { resource: services.yml }
我制作了一个实体名称 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;
}
}
但我不知道如何获得 S3 适配器和客户端,因为在此示例中: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得它们。
我想要的只是一个使用示例。
