[英]symfony/FOSRestBundle : empty JSON response (using the symfony embodied serializer)
I'm learning to build API with symfony (using FOSRestBundle). 我正在学习使用symfony构建API(使用FOSRestBundle)。 I'm following a french tutorial.
我正在学习法语教程。 Obviously, I first try to write the code by myself but even with a copy/paste, it keeps get me empty JSON array when I do a GET request to the appropriate route (rest-api.local/places).
显然,我首先尝试自己编写代码,但即使使用复制/粘贴,当我向相应的路径(rest-api.local / places)发出GET请求时,它仍然会让我获得空的JSON数组。
The code works OK if I "format" the code in php array: 如果我“格式化”php数组中的代码,代码工作正常:
public function getPlacesAction(Request $request)
{
$places = $this->get('doctrine.orm.entity_manager')
->getRepository('AppBundle:Place')
->findAll();
/* @var $places Place[] */
$formatted = [];
foreach ($places as $place) {
$formatted[] = [
'id' => $place->getId(),
'name' => $place->getName(),
'address' => $place->getAddress(),
];
}
return new JsonResponse($formatted);
}
but then I try to serialize directly $places, using the view handler of fost Rest (in config.yml) 但后来我尝试直接序列化$ places,使用fost Rest的视图处理程序(在config.yml中)
fos_rest:
routing_loader:
include_format: false
view:
view_response_listener: true
format_listener:
rules:
- { path: '^/', priorities: ['json'], fallback_format: 'json' }
and changing my function in my controller to the following code, I get my JSON response but without anything between "{ [],[],[]}" (and I do have 3 entries in my DB): 并将我的控制器中的功能更改为以下代码,我得到了我的JSON响应,但“{[],[],[]}”之间没有任何内容(我的数据库中有3个条目):
public function getPlacesAction(Request $request)
{
$places = $this->get('doctrine.orm.entity_manager')
->getRepository('AppBundle:Place')
->findAll();
/* @var $places Place[] */
return $places;
}
It's my first post on stackoverflow, so I hope my question is clear, Have a nice day. 这是我关于stackoverflow的第一篇文章,所以我希望我的问题很清楚,祝你有愉快的一天。
In my app/config/services.yml
I've added this: 在我的
app/config/services.yml
我添加了这个:
services:
object_normalizer:
class: Symfony\Component\Serializer\Normalizer\GetSetMethodNormalizer
# Important! Tag this service or it wouldn't work
tags:
- { name: serializer.normalizer }
I still can't get why it works but all of a sudden I've got a nice json in response. 我仍然无法理解为什么它有效但突然间我有一个很好的json作为回应。
