form 验证方法体controller中直接书写

$params = Request()->all();
$rules = [
    'user_phone' => 'required',
    'user_name'=>'required|string',
    'company_name'=>'required|string',
];

$messages = [
    'user_phone.required' => '手机号必填',
    'user_name.required'=>'用户名必填',
    'company_name.required'=>'用户名必填',
];

$validator = Validator::make($params, $rules, $messages);

if ($validator->fails()) {
    return Response()->json( ['code' => 400, 'message' => $validator->errors()->first()]);
}
