我正在尝试使用Apigility中的Doctrine将一个实体链接到一个实体。关系是1幻灯片有很多子弹点。所以我希望返回json显示每个幻灯片及其所有相关的嵌套项目符号。但正如你从下面的输出中看到的那样，子弹总是返回空：
{

"self": {
"href": "http://0.0.0.0:8888/slide"
}
},
"_embedded": {
"slide": [

"id": "2",
"title": "Title",
"previous": "Previous",
"next": "Next",
"bullets": {},
"_links": {

}
}
},
{

答案 0 :(得分：0)
您的getBullets方法返回ArrayCollection实例，Hal渲染器不知道如何渲染（序列化）此对象，这就是您看到{}（json格式的对象）的原因。您应该添加一个自定义水合器/提取器，为您的bullits返回一些可渲染值。例如，您可以将其设置为Hal\Collection实例。
在您的保湿器/提取器中，您可以执行以下操作：
<?php
namespace Application\Extractor;
use Zend\Stdlib\Extractor\ExtractionInterface;
use ZF\Hal;
class SlideExtractor implements ExtractionInterface
public function extract($object){
$data = [];
$route = //...your route to bullits
$routeParams = //...route params if needed
$bullits = $object->getBullits()->toArray();
$collection = new Hal\Collection($bullits, $route, $routeParams);
$data['bullits'] = $collection;
//...other extractions from your slide ( $object )
return $data;
}
}
