My entity FosUserBundle
namespace AppBundle'Entity;
use JMS'Serializer'Annotation'Expose;
use JMS'Serializer'Annotation'Exclude;
use JMS'Serializer'Annotation'ExclusionPolicy;
use Doctrine'ORM'Mapping as ORM;
use FOS'UserBundle'Model'User as BaseUser;
use FOS'UserBundle'Model'Group;
/**
* User
*
* @ORM'Table(name="user")
* @ORM'Entity(repositoryClass="AppBundle'Repository'UserRepository")
* @ExclusionPolicy("all")
*/
class User extends BaseUser
{
/**
* @ORM'Id
* @ORM'Column(type="integer")
* @ORM'GeneratedValue(strategy="AUTO")
* @Exclude
*/
protected $id;
/**
* @ORM'Column(type="integer")
*/
private $balance = 0;
但是如果我尝试序列化应用程序''实体''用户对象:
$this->get('jms_serializer')->serialize($user, 'json');
它返回了我的ID字段!
{
"id": 1,
"username": "admin",
"username_canonical": "admin",
"email": "admin",
"email_canonical": "admin",
"enabled": true,
"salt": "o12yxgxp3vkk0w4sck80408w8s8o84s",
"password": "$2y$13$o12yxgxp3vkk0w4sck804uSVjSMSB1W0qwEjunGTHomBqqoGvkW9G",
"last_login": "2016-02-28T17:28:19+0300",
"locked": false,
"expired": false,
"roles": [
"ROLE_ADMIN"
],
"credentials_expired": false
}
由于 FOSUserBundle 序列化程序规则,排除策略将不起作用。
若要使用排除项,需要告诉 JMSSerializer 压缩 FOSUB 序列化。
在config.yml
中添加以下内容:
jms_serializer:
metadata:
auto_detection: true # Don't forget this line
directories:
FOSUB:
namespace_prefix: FOS'UserBundle
path: %kernel.root_dir%/serializer/FOSUB
然后,创建文件app/serializer/FOSUB/Model.User.yml
并将以下内容粘贴到:
FOS'UserBundle'Model'User:
exclusion_policy: ALL
现在,所有继承的属性都被排除在外,您可以公开所需的属性。
如果要保留某些属性,或在实体中重新定义它们,请根据需要对其进行调整。
请参阅相应的问题 #78。
更新
对于不起作用的@Expose注释,请添加auto_detection
,如我前面的示例所示。
如果这不能解决问题,请使用@Groups
注释并执行以下操作:
use JMS'Serializer'Annotation'Groups;
/**
* @ORM'Column(type="integer")
* @JMS'Groups({"user"})
*/
private $balance = 0;
像这样更改控制器:
use JMS'Serializer'SerializationContext;
$context = SerializationContext::create()->setGroups(array('user'));
$serializer->serialize($user, 'json', $context);
它应该有效。
请记住,此问题的存在只是因为您的 User 实体扩展了已具有序列化程序规则的类。
$serializer = SerializerBuilder::create()
->setSerializationContextFactory(function () {
return 'JMS'Serializer'SerializationContext::create()
->setSerializeNull(true)
;
})
->setDeserializationContextFactory(function () {
return 'JMS'Serializer'DeserializationContext::create()
->setSerializeNull(true)
;
})
->setAnnotationReader($annotationReader)
->setPropertyNamingStrategy(new SerializedNameImportantThanPropertyNameStrategy())
->build();
忽略某些父类:CComponent、CModel、CActiveRecord
$class = new 'ReflectionClass($serializer);
$property = $class->getProperty('navigator');
$property->setAccessible(true);
$navigator = $property->getValue($serializer);
$class = new 'ReflectionClass($navigator);
$property = $class->getProperty('metadataFactory');
$property->setAccessible(true);
$metadataFactory = $property->getValue($navigator);
$class = new 'ReflectionClass($metadataFactory);
$property = $class->getProperty('loadedClassMetadata');
$property->setAccessible(true);
$property->setValue($metadataFactory, [
'CComponent' => new NullMetadata(new 'stdClass()),
'CModel' => new NullMetadata(new 'stdClass()),
'CActiveRecord' => new NullMetadata(new 'stdClass()),
]);
