验证器 模型对应验证处理

<?php

//验证器

class Staff extends Validate
{
 protected $rule = [
  'name' => 'require|length:4,15',
  'sex' => 'in:0,1',
  'age' => 'require|between:18,60',
  'salary' => 'require|gt:1500',
 ];

 //错误信息
 protected $message = [
  'name.require' => '员工姓名不能为空',
  'name.length' => '姓名信息必须在4到15个字符之间',
  'sex.in' => '性别必须是男或者女',
  'age.require' => '年龄不能为空',
  'age.between' => '年龄必须在18到60岁之间',
  'salary.require' => '工资不能为空',
  'salary.gt' => '工资必须大于1500'
 ];
}

<?php
namespace app\index\controller;
use think\Controller;
use app\validate\Staff;//导入验证器类
use think\Validate;

  ];
  $validate = new Staff();
  if(!$validate->check($data)){
   dump($validate->getError());
  }else {
   return '验证通过~~';
  }
 }

 //验证器简化
 public function demo2()
 {
  //准备要验证的数据
  // $data = [

  $res = $this->validate($data,$rule,$mess);
  if(true !== $res){
   return $res;

 //独立验证
