在我的 Restful API 中，我想一次调用上传文件。在我的测试中，表单同时被初始化和绑定，但是我所有的数据字段表单都是空的，结果是我的数据库中的一条空记录。
如果我通过表单视图然后提交它，一切都很好，但我想一次调用 Web 服务。Web 服务注定要由主干应用程序使用。
谢谢你的帮助。
我的测试：
$client = static::createClient();
$photo = new UploadedFile(
'/Userdirectory/test.jpg',
'photo.jpg',
'image/jpeg',
14415
);
$crawler = $client->request('POST', '/ws/upload/mydirectory', array(), array('form[file]' => $photo), array('Content-Type'=>'multipart/formdata'));
有我的控制器动作：
public function uploadAction(Request $request, $directory, $_format)
{
$document = new Media();
$document->setDirectory($directory);
$form = $this->createFormBuilder($document, array('csrf_protection' => false))
/*->add('directory', 'hidden', array(
'data' => $directory
))*/
->add('file')
->getForm()
;
if ($this->getRequest()->isMethod('POST')) {
$form->bind($request);
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($document);
$em->flush();
if($document->getId() !== '')
return $this->redirect($this->generateUrl('media_show', array('id'=>$document->getId(), 'format'=>$_format)));
}else{
$response = new Response(serialize($form->getErrors()), 406);
return $response;
}
}
return array('form' => $form->createView());
}
