1.目录结构

 2.控制器引用

 protected $validate;

 public function __construct()
    {
        $this->validate = new IndexValidate();//引入该控制器对应的验证规则
        parent::__construct();
    }

/*
 *验证前端提交的post值
 *
*/
public function Index()
{
  $posts = $this->request->post();
  $this->validate->scene("index")->check($posts) || $this->error($this->validate->getError(), [], 202);
}

3.validate文件

class IndexValidate extends Validate
{
    //规则定义
    protected $rule = [
        "page" => "require|egt:1",// >=1
        "per_page" => "require|elt:15|egt:1"// 1=<per_page<=15
    ];
    //场景定义
    protected $scene = [
        "index" => ["page", "per_page"]
    ];
}

4.validate规则
