think php 未登录，禁止访问页面 + 退出登录_登录页面

 

 

1.首先在Local创建一个基类控制器

D:\PHP\phpstudy_pro\WWW\1906A\pyg>php think make:controller goods/Base --plain
Controller created successfully.

2:判断页面是否有session值，，没有就跳转会登录页面，登录后进行访问

<?php

namespace app\goods\controller;

use think\Controller;
use think\Request;

class Base extends Controller
{
    //
    public function __construct(Request $request = null)
    {
        parent::__construct($request);
        if (!session('?name')){
            $this->error('您还没有登录,请登录后在进行访问.........','/goods/login/create');
        }
    }


}
