Symfony中的序列化和反序列化 [英] Serializing and Deserializing in Symfony

问题描述

我正在使用Symfony捆绑包"symfony/serializer"对实体进行序列化.

I am serializing entities with the Symfony bundle "symfony/serializer".

我能够毫无问题地将我的实体编码为json，但是我在反序列化并将其恢复为原始格式时遇到了问题.我收到的错误是;

I am able to encode my entity into json with no problems, however I am having problems deserializing it and bringing it back into its original form. The error I am receiving is;

Could not denormalize object of type AppBundle:Entity, no supporting normalizer found.

DefaultController.php

DefaultController.php

    //Create Entity to Serialize
    $entity = new Entity();
    $entity->setId(1);
    $entity->setName('john');

    //create serializer to serialize entity
    $encoders = array(new XmlEncoder(), new JsonEncoder());
    $normalizers = array(new ObjectNormalizer());
    $serializer = new Serializer($normalizers, $encoders);
    $jsonContent = $serializer->serialize($entity, 'json');

    var_dump($jsonContent); // returns string '{"id":1,"name":"john"}' (length=22)  << GOOD!


    //Deserialize entity
    $person = $serializer->deserialize($jsonContent, 'AppBundle:Entity', 'json');
    //<ERROR HERE>//

    var_dump($person); 

Entity.php

Entity.php

namespace AppBundle\Entity;

class Entity {

private $id;

private $name;

public function getId()
{
    return $this->id;
}

public function setId($id)
{
    $this->id = $id;
}

public function getName()
{
    return $this->name;
}

public function setName($name)
{
    $this->name = $name;
}

}

不太确定我缺少什么，任何帮助将不胜感激.

Not too sure what I am missing, any help greatly appreciated.

推荐答案

deserialize()应该获取实体的名称空间，因此您需要进行更改 AppBundle:Entity至AppBundle\Entity.

deserialize() should get the namespace of the entity so you need to change AppBundle:Entity to AppBundle\Entity.

$person = $serializer->deserialize($jsonContent, 'AppBundle\Entity', 'json');
