think php 验证器及验证场景的使用

<?php
namespace app\api\validate;

use think\Validate;

class Goods extends Validate
{
    protected $rule = [
        ‘goodName|商品名称‘  =>  ‘require‘,
        ‘number|商品编号‘ =>  ‘require‘,
        ‘price|商品价格‘ =>  ‘require‘,
        ‘prices|成品价格‘ =>  ‘require‘,
        ‘weight|商品重量‘=>  ‘require‘,
        ‘img|图片‘=>  ‘require‘,
    ];

    protected $scene=[
      ‘add‘=>[‘goodName‘,‘number‘,‘price‘,‘prices‘,‘weight‘,‘img‘]
    ];

}

<?php

namespace app\api\controller;

use think\Controller;
use think\Loader;
use think\Request;

class Api extends Controller
{
/**
     * 显示创建资源表单页.
     *
     * @return \think\Response
     */
    public function create()
    {
        //
      return view();
    }


    public function save(Request $request)
    {
        //
        $data=$request->param();
     $data[‘img‘]=$request->file(‘img‘);
//进行参数的验证、
        $validate = Loader::validate(‘Goods‘);
        if(!$validate->scene(‘add‘)->check($data)){
            $this->error($validate->getError());
        }


    }
