我通过编写自己的 GetSetNormalizer 我的课程解决了同样的问题。在类中定义静态变量以进行分支
class LimitedRecursiveGetSetMethodNormalizer extends GetSetMethodNormalizer
{
public static $limit=2;
/**
* {@inheritdoc}
*/
public function normalize($object, $format = null)
{
$reflectionObject = new \ReflectionObject($object);
$reflectionMethods = $reflectionObject->getMethods(\ReflectionMethod::IS_PUBLIC);
$attributes = array();
foreach ($reflectionMethods as $method) {
if ($this->isGetMethod($method)) {
$attributeName = strtolower(substr($method->name, 3));
$attributeValue = $method->invoke($object);
if (null !== $attributeValue && !is_scalar($attributeValue) && LimitedRecursiveGetSetMethodNormalizer::$limit>0) {
LimitedRecursiveGetSetMethodNormalizer::$limit--;
$attributeValue = $this->serializer->normalize($attributeValue, $format);
LimitedRecursiveGetSetMethodNormalizer::$limit++;
}
$attributes[$attributeName] = $attributeValue;
}
}
return $attributes;
}
/**
* Checks if a method's name is get.* and can be called without parameters.
*
* @param ReflectionMethod $method the method to check
* @return Boolean whether the method is a getter.
*/
private function isGetMethod(\ReflectionMethod $method)
{
return (
0 === strpos($method->name, 'get') &&
3 < strlen($method->name) &&
0 === $method->getNumberOfRequiredParameters()
);
}
}
和用法
LimitedRecursiveGetSetMethodNormalizer::$limit=3;
$serializer = new Serializer(array(new LimitedRecursiveGetSetMethodNormalizer()), array('json' => new
JsonEncoder()));
$response =new Response($serializer->serialize($YOUR_OBJECT,'json'));
