think php 未登录，禁止访问页面 + 退出登录

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‘);
        }
    }


}

3：

、、、、、、、、表单页面的退出登录

"-1" href="/goods/login/loginOut">安全退出

php

namespace app\goods\controller;

use app\goods\model\GoodModel;
use think\Controller;
use think\Loader;
use think\Request;
use think\Validate;

class Login extends Controller
{
    //展示登录表单
    public function create()
    {
        //goods/login/create
        //通过域名/模块名/控制器名/方法名访问登录页面
        return view();
    }

    //登录处理，验证参数
    public function save(Request $request)
    {
        //
        $params = $request->param();
        //验证参数、非空
        $rule = [
            ‘account‘ => ‘require‘,
            ‘password‘ => ‘require‘,
            ‘cord‘ => ‘require‘,
        ];
        $tips = [
            ‘account.require‘ => ‘账号不可以为空‘,
            ‘password.require‘ => ‘密码不可以为空‘,
            ‘cord.require‘ => ‘验证码不可以为空‘,
        ];
        $validate = new Validate($rule, $tips);
        $result = $validate->check($params);
        if (!$result) {
            $this->error($validate->getError());
        }
//数据库验证参数
        $data = GoodModel::login($params);
        //验证账号
        if ($params[‘account‘] != $data[‘name‘]) {
            $this->error(‘账号错误‘, ‘/goods/login/create‘);
        }
        //验证密码
        if (md5($params[‘password‘]) != md5($data[‘password‘])) {
            $this->error(‘密码错误‘, ‘/goods/login/create‘);
        }
        //验证码进行验证
        if (!captcha_check($params[‘cord‘])) {
            $this->error(‘验证码输入错误‘, ‘/goods/login/create‘);
        };
        if ($data) {
            //记录session
            session(‘name‘, $data[‘name‘]);
            $this->success(‘登录成功‘, ‘/goods/goods/index‘);
        }


    }

//退出登录
    public function loginOut()
    {
        //清除session
        session(‘name‘,null);
        //返回登录页面
        $this->success(‘正在退出，请稍等‘,‘/goods/login/create‘);



    }
