我有以下代码:
public function adminListAction(Request $request)
{
if (!$this->isGranted('ROLE_ADMIN')) {
return new JsonResponse("Not granted");
}
$page = $request->query->get('page', 1);
$criteria = new DocumentaryCriteria();
$criteria->setStatus(DocumentaryStatus::PUBLISH);
$criteria->setSort([
DocumentaryOrderBy::CREATED_AT => Order::DESC
]);
$qb = $this->documentaryService->getDocumentariesByCriteriaQueryBuilder($criteria);
$adapter = new DoctrineORMAdapter($qb, false);
$pagerfanta = new Pagerfanta($adapter);
$pagerfanta->setMaxPerPage(12);
$pagerfanta->setCurrentPage($page);
$items = (array) $pagerfanta->getCurrentPageResults();
$data = [
'items' => $items,
'count_results' => $pagerfanta->getNbResults(),
'current_page' => $pagerfanta->getCurrentPage(),
'number_of_pages' => $pagerfanta->getNbPages(),
'next' => ($pagerfanta->hasNextPage()) ? $pagerfanta->getNextPage() : null,
'prev' => ($pagerfanta->hasPreviousPage()) ? $pagerfanta->getPreviousPage() : null,
'paginate' => $pagerfanta->haveToPaginate(),
];
return new JsonResponse($data);
}返回以下内容,请注意空对象的数组
{“项目”:{},"count_results":9,"current_page":1,"number_of_pages":1,"next":null,"prev":null,“分页”:false }
通过这样做,我知道它们的属性不是空的:
foreach ($items as $item) {
echo $item->getTitle();
}//返回“纪录片1”

这个问题很可能是您的$item对象不能被json序列化。
尝试在该类中实现JsonSerializable接口(https://www.php.net/manual/en/class.jsonserializable.php),并向item类添加如下方法:
public function jsonSerialize() {
return [
'title' => $this->getTitle(),
'foo' => $this->bar(),
];
