如何在Laravel中向API发送验证消息？

我正在使用Laravel 8并正在研究API。我已经创建了用于表单验证的请求类，但是当移动开发人员点击api验证消息时，未按要求显示消息。这是我的控制器方法

 public function store(InvoiceStoreRequest $request)
{
    try {
        return $this->responseWithSuccess(true,'Invoice Data',
               $this->invoiceInterface->store($request), Response::HTTP_OK);
    }catch (\Exception $exception){
        return $this->responseWithError($exception->getMessage(),Response::HTTP_OK);
    }
}

在这里，我正在使用InvoiceStoreRequest类来验证表单。InvoiceStoreRequest的代码如下

public function rules()
{
    return [
        'id' => ['required', 'string'],
        'invoice_date' => ['required', 'date'],
        'reference_number' => ['required'],
        'vendor_id' => ['required'],
        'invoice_net_total' => ['required','regex:/^\d*(\.\d{1,2})?$/'],
        'invoice_tax_total' => ['required', 'regex:/^\d*(\.\d{1,2})?$/'],
        'invoice_gross_total' => ['required', 'regex:/^\d*(\.\d{1,2})?$/'],
        'item_count' => ['required', 'numeric'],
        'invoice_type' => ['required','regex:(order|refund)'],
        'provider' => ['required'],
        'detail_url' => ['required'],
        'invoice_photo_url' => ['required'],
    ];
}

为了显示自定义消息，

public function messages()
{
    return [
        'invoice_type.regex' => 'The invoice type format is invalid. Invoice Type should be [order,refund]',
        'invoice_net_total.regex' => 'Invoice Net must be Decimal or Numeric value.',
        'invoice_tax_total.regex' => 'Invoice Tex must be Decimal or Numeric value.',
        'invoice_gross_total.regex' => 'Invoice Gross must be Decimal or Numeric value.',
    ];
}

对邮递员来说效果很好。但是，当移动开发人员使用API时，他收到422无法处理的实体的错误，但未显示错误消息。我想显示错误消息。
我该如何解决。谢谢

尝试这样的事情：

 $validator = Validator::make(request()->all(), [
          'name'     => 'required',
          // ... Rules 
        ]);

        if ($validator->fails()) {
            return response()->json([
              'errors' => $validator->errors(),
              'status' => Response::HTTP_BAD_REQUEST,
            ], Response::HTTP_BAD_REQUEST);
        }

        MODEL::create($validator->validated());

        return response()->json([
          'data'   => [],
          'status' => Response::HTTP_CREATED,
        ], Response::HTTP_CREATED);
