如何在RESTful服务中通过POST请求添加订单？

如何解决如何在RESTful服务中通过POST请求添加订单？

我正在尝试为具有JWT身份验证的客户面板添加订单。 我激活了授权，在Postman的正文中添加了参数并发送了它，但是“ status”：422，“ errors”：“ Order no valid”}它给出了此消息，并且dev.log文件在下面。

我有两个实体类，分别是User和Order，并且User的变量是“ username，password，orders”（orders变量具有OneToMany关系和mappingBy =“ user”）。Order的变量是“ productId，quantity，address，shippingDate和用户（用户具有ManyToOne关系并且inversedBy =“ orders”）

我的addOrder函数在下面，

/**
 * @param Request $request
 * @param TokenStorageInterface $tokenStorage
 * @return JsonResponse
 * @Route("/orders",name="orders_add",methods={"POST"})
 */
public function addOrder(Request $request,TokenStorageInterface $tokenStorage)
{
    $entityManager = $this->getDoctrine()->getManager();

    try{
        $request = $this->transformJsonBody($request);

        if (!$request || !$request->request->get('productId') || !$request->request->get('quantity') || !$request->request->get('address') || !$request->request->get('shippingDate')){
            throw new Exception();
        }

        $user = $tokenStorage->getToken()->getUser();
        $order = new Order();

        $order->setProductId($request->get('productId'));
        $order->setQuantity($request->get('quantity'));
        $order->setAddress($request->get('address'));
        $order->setShippingDate($request->get('shippingDate'));
        $order->setUser($user);
        $entityManager->persist($order);
        $entityManager->flush();


        $data = [
            'status' => 200,'success' => "Order added successfully",];
        return $this->response($data);

    }catch (Exception $e){
        $data = [
            'status' => 422,'errors' => "Order no valid",];
        return $this->response($data,422);
    }
}

我已经阅读了很多文章并与很多人进行了交谈，但是自上个月以来，我正在学习REST API，在这个主题上我是一个新手，但是我想学习它。

谢谢
