symfony - $data = json_decode($request->getContent(), true); 返回正确的数据，但 $form->getData() 即使在 $form->submit($data) 之后也返回 null

Question

我正在使用 Angular 和 FOSRestBundle

@Injectable({
  providedIn: 'root'
})
export class DataService {
  constructor(private url: string, private http: HttpClient) { }

  create(resource) {
    console.log("url: " + this.url);
    console.log(resource);
    return this.http.post(this.url  + "?access_token=YjJkNWU0ZDE5NjgxNGM5MmYzYTYxOGY0YzNmZjgxNDAzY2QzNTA5MmI2NjEyMWMzMDhlM2NlM2JmYzk4ZGQ5Mg", JSON.stringify(resource));
  }

}

如您所见，Angular 正在发送正确的数据。

我的控制器动作：

/**

     *
     * @param Request $request
     * @return JsonResponse

    public function createDocumentaryAction(Request $request)
    {
        $documentary = new Documentary();

        $headers = [
            'Content-Type' => 'application/json',
            'Access-Control-Allow-Origin' => '*'
        ];
        $form = $this->createForm(AdminDocumentaryForm::class, $documentary);
        $data = json_decode($request->getContent(), true);
        $form->submit($data);

        //return new JsonResponse($data, 200, $headers);
        //return new JsonResponse($form->getData(), 200, $headers);

        if ($form->isValid()) {
            return new JsonResponse($form->getData(), 200, $headers);
        } else {
            $errors = (string) $form->getErrors(true, false);
            return new JsonResponse($errors, 400, $headers);
        }

return new JsonResponse($data, 200, $headers);返回

但$form->getData()返回这个：

目的 { }

$form->submit($data);似乎没有工作。

我不知道我错过了什么，你能帮忙吗？
