TYPO3 Extbase-无法通过typnum渲染json
TYPO3 Extbase - Failing to render json via typnum
在list/edit/new/remove动作旁边(有效)，我尝试将输出呈现为json.但是，没有价值可呈现.如果我做的简单...
Next to list/edit/new/remove action (which work) I tried to render the output in json. But no values render. If I do a simple ...
$data = array('value'=>'001');
return json_encode($data);
它确实返回...
{"value":"001"}
我想念什么?
通过使用并引用相同的存储库，其工作原理:
With using and referencing to the same repository its working:
JSONController.php
JSONController.php
<?php
namespace Vendor\Lei\Controller;
use Vendor\Lei\Domain\Model\Lei;
/**
* JSONController
*/
class JSONController extends \TYPO3\CMS\Extbase\Mvc\Controller\ActionController {
/**
* leiRepository
*
* @var \Vendor\Lei\Domain\Repository\LeiRepository
* @inject
*/
protected $leiRepository;
/**
* @var string
*/
protected $defaultViewObjectName = 'TYPO3\CMS\Extbase\Mvc\View\JsonView';
/**
* action jsonRequest
*
* @return void
*/
public function jsonRequestAction() {
//$data = array('value'=>'001');
//return json_encode($data);
$this->view->setVariablesToRender(array('records'));
$this->view->assign('records', $this->leiRepository->jsonRequest());
}
}
LeiRepository.php
LeiRepository.php
<?php
namespace Vendor\Lei\Domain\Repository;
use TYPO3\CMS\Extbase\Persistence\QueryInterface;
class LeiRepository extends \TYPO3\CMS\Extbase\Persistence\Repository {
...
public function jsonRequest() {
$query = $this->createQuery();
$result = $query->setLimit(100)->execute();
return $result;
}
}
推荐答案
如果注入并使用JsonRepository extbase，则会扩展名为Json的域对象.如果只想将现有的域对象呈现为其JSON表示形式，则只需使用在listAction()和detailAction()中使用的相同存储库即可.
If you inject and use a JsonRepository extbase expexts a domain object called Json. If you just want to render already existing domain objects as their JSON representation, just use the same repositories you used in your listAction() and detailAction().
看看我的示例: https://usetypo3.com/json-view.html
此外，像在存储库中一样，在return之后进行的调试也将永远不会执行.
Also, a debug after the return like you did in your repository will never be executed.
