Friends who need it can refer to it. I hope it can help everyone. .

Admin.php in the controller file

<?php
namespace app\admin\controller;
use think\Controller;
use app\admin\model\Admin as AdminModel;  //使用分页类 取别名解决类名冲突
class Admin extends Controller{
  public function lst(){
/* 分页开始  */
    $list = AdminModel::paginate(3);
    $this -> assign(&#39;list&#39;,$list);
/* 结束 */
    return $this->fetch(&#39;lst&#39;);
  }
  public function add(){
    //判断页面是否提交
    if(request()->isPost()){
      //打印接收到的参数
      //dump(input(&#39;post.&#39;));
      $data = [  //接受传递的参数
        &#39;username&#39; => input(&#39;username&#39;),
        &#39;password&#39; => md5(input(&#39;password&#39;)),
      ];
/*验证开始*/
      $validate = \think\Loader::validate(&#39;Admin&#39;);
            /* scene(&#39;add&#39;) 在add页面添加验证应用  */
      if(!$validate -> scene(&#39;add&#39;)-> check($data)){
        /* 验证失败打印 */
        $this -> error($validate->getError());
        die;
      }
/*结束*/
    /* Db(&#39;表名&#39;) 数据库助手函数*/
      if(Db(&#39;admin&#39;) -> insert($data)){    //添加数据
        return $this->success(&#39;添加成功&#39;,&#39;lst&#39;); //成功后跳转 lst 界面
      }else{
        return $this->error(&#39;添加管理员失败&#39;);
      }
      return;
    }
    return $this->fetch(&#39;add&#39;);
  }
}
