我完全迷失了。在它开始毫无意义之前,人们可以阅读的文档非常多。
我希望能够保存从Symfony应用程序外部传递的表单数据。我已经安装了FOSRestBundle,JMSSerializerBundle,NelmioCorsBundle等。
首先,我有一个如下所示的FormType:
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('title')
->add('requestDate')
->add('deliverDate')
->add('returnDate')
->add('created')
->add('updated')
->add('contentChangedBy')
;
}
然后我有一个包含POST方法的REST控制器,它应该存储新记录:
class AvRequestController extends Controller
{
...
public function postAvrequestAction(Request $request){
$entity = new AvRequest();
$form = $this->createForm(new AvRequestType(), $entity);
$form->handleRequest($request);
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($entity);
$em->flush();
return new \Symfony\Component\HttpFoundation\JsonResponse($entity, Codes::HTTP_CREATED);
}
return new \Symfony\Component\HttpFoundation\JsonResponse($request, 400);
}
}
以下是使用模拟ajax表单数据的测试:
$('#postform').submit(function(event){
event.preventDefault();
console.log("submitted");
ajaxObject = {
url: $("#postform").attr("action"),
type: 'POST', // Can be GET, PUT, POST or DELETE only
dataType: 'json',
xhrFields: {
withCredentials: true
},
crossDomain: true,
contentType: "application/json; charset=UTF-8",
data: JSON.stringify({"id":2, "title":"billabong", "requestDate":"2000-01-01 11:11:11", "deliverDate": "2000-01-01 11:11:11", "returnDate": "2000-01-01 11:11:11", "created": "2000-01-01 11:11:11", "updated": "2000-01-01 11:11:11", "content_changed_by":"cpuzzuol"})
};
// ... Add callbacks depending on requests
$.ajax(ajaxObject)
.done(function(data,status,xhr) {
console.log( two );
})
.fail(function(data,status,xhr) {
console.log( status );
})
.always(function(data,status,xhr) {
console.log( data );
});
console.log("END");
});
当我提交表单时,我的POST方法会触发400 Bad Request。更糟糕的是,我的$ request包一直是空的:
{"attributes":{},"request":{},"query":{},"server":{},"files":{},"cookies":{},"headers":{}}
如果我这样做
$request->getContent()
我得到了我的字符串化数据:
"{\u0022id\u0022:2,\u0022title\u0022:\u0022billabong\u0022,\u0022requestDate\u0022:\u00222000-01-01 11:11:11\u0022,\u0022deliverDate\u0022:\u00222000-01-01 11:11:11\u0022,\u0022returnDate\u0022:\u00222000-01-01 11:11:11\u0022,\u0022created\u0022:\u00222000-01-01 11:11:11\u0022,\u0022updated\u0022:\u00222000-01-01 11:11:11\u0022,\u0022content_changed_by\u0022:\u0022cpuzzuol\u0022}"
我读过这可能与FOSRestBundle的“身体监听器”有关,但我已经启用了:
body_listener: true
更新
body_listener似乎根本没有发挥作用。正如下面的答案所述,您必须创建一个空白名称的表单,因为您从系统外部提交的表单不具有通常在Symfony内部生成的名称。另外,如果您最初没有设置,请务必关闭CSRF。
答案 0 :(得分:1)
表单isValid
也会检查CSRF token validation
。您可以在csrf token validation
中关闭AvRequestType
。
//...
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\AvRequest',
'csrf_protection' => false
));
}
//...
另外,我建议您的表单为name
。 isValid还会检查您的form name
。
// form without name
public function getName()
{
return '';
}
或
$form = $this->get('form.factory')->createNamed('', new AvRequestType(), $avRequest);
如果你想创建实体,你应该发送data
没有id(来自JS)。
我使用过" JMS序列化器"将我的实体序列化为json。 //控制器
public function postAvRequestAction(Request $request)
{
$avRequest = new AvRequest();
$form = $this->createForm(new AvRequestType(), $avRequest);
$form->handleRequest($request);
$form = $this->get('form.factory')->createNamed('', new AvRequestType(), $avRequest);
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($avRequest);
$em->flush();
$serializer = $this->get('serializer');
$serialized = $serializer->serialize($avRequest, 'json');
return new Response($serialized);
}
return new JsonResponse(array(
'errors' => $this->getFormErrors($form)
));
}
protected function getFormErrors(Form $form)
{
$errors = array();
foreach ($form->getErrors() as $error) {
$errors['global'][] = $error->getMessage();
}
foreach ($form as $field) {
if (!$field->isValid()) {
foreach ($field->getErrors() as $error) {
$errors['fields'][$field->getName()] = $error->getMessage();
}
}
}
return $errors;
}
