问题描述
我正在使用Symfony 2与Doctrine 2。我需要使用加密服务加密我的实体中的一个字段,我想知道我应该在哪里这个逻辑。
我正在使用Controller> Service> Repository架构。
我想知道一个听众将是一个好主意,我的主要关注是,如果我的实体被加密存储,如果我在它的状态下解密它将被改变,我不知道这是一个好主意。
你将如何实现这一点?
要在 >和 targnation 的很好的答案,一种将依赖关系(例如,加密服务)注入到自定义的Doctrine映射类型中的方法可能是使用静态属性和设置器:
// MyBundle / Util / Crypto / Types / EncryptedString.php
class EncryptedString extends StringType
{
/ * * @var \MyBundle\Util\Crypto * /
protected static $ crypto;
public static function setCrypto(Crypto $ crypto)
{
static :: $ crypto = $ crypto;
}
public function convertToDatabaseValue($ value,AbstractPlatform $ platform)
{
$ value = parent :: convertToDatabaseValue($ value,$ platform);
return static :: $ crypto-> encrypt($ value);
}
public function convertToPHPValue($ value,AbstractPlatform $ platform)
{
$ value = parent :: convertToPHPValue($ value,$ platform);
return static :: $ crypto-> decrypt($ value);
}
public function getName()
{
return'encrypted_string';
}
}
配置如下所示:
// MyBundle / MyBundle.php
class MyBundle extends Bundle
{
public function boot()
{
/ ** @var \MyBundle\Util\Crypto $ crypto * /
$ crypto = $ this-> container-> get('mybundle.util.crypto' );
EncryptedString :: setCrypto($ crypto);
}
}
#app / Resources / config.yml
doctrine:
dbal:
types:
encrypted_string: MyBundle\Util\Crypto\Types\EncryptedString
#MyBundle / Resources / config / services.yml
services:
mybundle.util.crypto:
类:MyBundle\Util\Crypto
参数:[%key%]
I'm using Symfony 2 with Doctrine 2.
I need to encrypt a field in my entity using an encryption service, and I'm wondering where should I put this logic.
I'm using a Controller > Service > Repository architecture.
I was wondering if a listener would be a good idea, my main concern is, if my entity is stored encrypted, if I decrypt it on the fly its state it's gonna be changed and I'm not sure it's a good idea.
How would you implement this?
To expand on richsage and targnation's great answers, one way to inject a dependency (e.g., cypto service) into a custom Doctrine mapping type, could be to use a static property and setter:
// MyBundle/Util/Crypto/Types/EncryptedString.php
class EncryptedString extends StringType
{
/** @var \MyBundle\Util\Crypto */
protected static $crypto;
public static function setCrypto(Crypto $crypto)
{
static::$crypto = $crypto;
}
public function convertToDatabaseValue($value, AbstractPlatform $platform)
{
$value = parent::convertToDatabaseValue($value, $platform);
return static::$crypto->encrypt($value);
}
public function convertToPHPValue($value, AbstractPlatform $platform)
{
$value = parent::convertToPHPValue($value, $platform);
return static::$crypto->decrypt($value);
}
public function getName()
{
return 'encrypted_string';
}
}
Configuration would look like this:
// MyBundle/MyBundle.php
class MyBundle extends Bundle
{
public function boot()
{
/** @var \MyBundle\Util\Crypto $crypto */
$crypto = $this->container->get('mybundle.util.crypto');
EncryptedString::setCrypto($crypto);
}
}
# app/Resources/config.yml
doctrine:
dbal:
types:
encrypted_string: MyBundle\Util\Crypto\Types\EncryptedString
# MyBundle/Resources/config/services.yml
services:
mybundle.util.crypto:
class: MyBundle\Util\Crypto
arguments: [ %key% ]
