我正在使用 Laravel 的驗證器來驗證控制器內的 JSON 請求：class InsertProduct extends ModuleApiController{    public function handle(Request $request, int $fileId)    {        $data = $request->json()->all();        $validator = Validator::make($data, [            'products' => ['required', new ArrayWithType('seq', 'The :field field must be an array')],            'products.*' => ['required', new ArrayWithType('assoc', 'The :field field must be an object')],            'products.*.code' => 'required|alpha_num',            'products.*.variants' => ['required', new ArrayWithType('seq', 'The :field field must be an array')],            'products.*.variants.*' => ['required', new ArrayWithType('assoc', 'The :field field must be an object')],            'products.*.variants.*.barcode' => 'required|alpha_num',        ]);字段products.*.code和products.*.variants.*.barcode字段可以是這樣的：20032199231"AB3123-X""Z22.327p""001230572""Houston22"我似乎找不到接受所有這些潛在值但拒絕數組或對象（Laravel 解析 JSON 后的關聯數組）值的規則。我嘗試過的事情： Rule                 | Issue----------------------|--------------------------------------------------------------------'required'            | Will validate JSON objects and arrays 'required|string'     | Won't validate integer values like the first one above'required|alpha_num'  | Won't validate the middle three values above'required|alpha_dash' | Won't validate values that contain periods (.) like the third one我需要的是類似的東西：'required|not_array'或者'required|scalar'但我在文檔中找不到類似的東西。我真的需要為此編寫自定義驗證規則嗎？
