编写验证规则：

<?php
declare (strict_types = 1);
namespace app\validate;
use think\Validate;

class Relation extends Validate {
    protected $rule = [
        'goods_name'  =>  'require|max:25',
        'goods_stock' =>  'require|number|egt:0',
        'goods_price' =>  'require|float|egt:0',
        'zipcode' => 'require|regex:\d{6}',  //邮政编码
        'city' => 'require|check_city',  //省市县
    ];

    protected $message  =   [
        'goods_name.require'  => '商品名称不能为空或者不能大于25个字符',
        'goods_stock.require' => '商品库存不能为空',
        'goods_stock.number'  => '商品库存只能是大于0的整数',
        'goods_stock.egt'     => '商品库存不能小于0',
        'goods_price.require' => '商品价格不能为空',
        'goods_price.float'   => '商品价格只能为数字',
        'goods_price.egt'     => '商品价格不能小于0',
        'zipcode.require' => '邮政编码不能为空',
        'zipcode.regex' => '邮政编码格式错误',
        'city.require' => '省市县不能为空',
        'city.check_city' => '省市县格式错误',
    ];

    protected $scene = [
        'add'  =>  ['goods_name','goods_stock','goods_price','zipcode','city'],
        'edit'  =>  ['goods_name','goods_stock','zipcode','city'],
    ];

    public function check_city($value)
    {
      
        return true;
    }

}



?>

控制器中调用验证规则

<?php
declare (strict_types = 1);
namespace app\controller;
use app\BaseController;
use think\Request;
use think\response\Json;
use app\validate\Relation as relationValidate;
class relation extends BaseController{

    //验证器
   public function index() : Json {
       $data = Request()->param();
       $relation = new relationValidate();
       if (!$relation->scene("edit")->check($data)) {
           return json(['code'=>'1','msg'=>$relation->getError()]);
       }

       return json(['code'=>'0','msg'=>'验证成功','data'=>$data]);
   }

}

?>
