TimoPHP做一个简单的后台登录、登出功能

 


 

登录控制器

登录控制器直接继承Timo\Core\Controller
其它需要登录后才能操作的控制器,继承自定义的公共控制器Admin,如Index控制器
通过AdminModel->checkAdmin($username, $password, $verify) 来验证登录
登录成功之后跳转到index/index

 

namespace app\admin\controller;


use app\admin\model\AdminModel;
use Timo\Captcha;
use Timo\Core\Controller;
use Timo\Core\Request;
use Timo\Core\Session;

class Login extends Controller
{
    /**
     * @var AdminModel
     */
    protected $AdminModel;

    public function __construct()
    {
        parent::__construct();

        $this->AdminModel = new AdminModel();
    }

    /**
     * 登录
     */
    public function index()
    {
        if (Request::isPost()) {
            $username = Request::post('username', '');
            $password = Request::post('password', '');
            $verify = Request::post('verify', '');

            $check_ret = $this->AdminModel->checkAdmin($username, $password, $verify);

            if ($check_ret['code'] == 1) {
                Session::delete('v_login');
                $this->redirect('index/index');
            }

            $this->assign('msg', $check_ret['msg']);
        }
        $this->view->set('layer_on', false);
        $this->display();
    }

    /**
     * 退出
     */
    public function logout()
    {
        Session::destroy();
        return $this->success('退出成功', 'login/index');
    }

    /**
     * 生成验证码
     */
    function verify()
    {
        $Captcha = new Captcha();
        $code = $Captcha->getCode();
        Session::set('v_login', $code);
        $Captcha->getImage();
    }
}

 

验证是否是管理员,并登录

验证成功之后,将管理员信息存入session
Session::set('u.uid', $admin_info['id']);
Session::set('u.name', $admin_info['username']);

 

namespace app\admin\model;


use Timo\Core\Model;
use Timo\Core\Session;

class AdminModel extends Model
{
    function __construct($dbType = '', $dbName = '')
    {
        parent::__construct($dbType, $dbName);
        $this->setTablePrefix('back_');
    }

    /**
     * 检测是否是管理员
     *
     * @param $username
     * @param $password
     * @param string $verify_code 验证码
     * @param bool $is_verify 是否验证验证码
     * @return array|string
     */
    public function checkAdmin($username, $password, $verify_code = '', $is_verify = true)
    {
        $admin_info = $this->getRow(array('username' => $username), 'id, username, password');

        if (!$admin_info) {
            return $this->result(4001, '没有该用户');
        }

        if ($is_verify && $verify_code != Session::get('v_login')) {
            return $this->result(4002, '验证码错误');
        }

        $password = sha1(md5($password));
        if ($admin_info['password'] == $password) {
            Session::set('u.uid', $admin_info['id']);
            Session::set('u.name', $admin_info['username']);
            return $this->result(1, '登录成功');
        }

        return $this->result(4003, '密码错误');
    }
}

 

后台公共控制器Admin

检测是否登录
Admin控制器在初始化的时候会检测是否已登录,没登录,将跳转到登录页面login/index

 

namespace app\admin\controller;


use Timo\Core\Controller;
use Timo\Core\Session;

class Admin extends Controller
{
    /**
     * 管理员信息['uid' => 1, 'name' => 'admin']
     *
     * @var mixed
     */
    protected $u;

    public function __construct()
    {
        parent::__construct();

        $this->u = Session::get('u');
        if (!empty($this->u)) {
            $this->assign('u', $this->u);
        } else {
            $this->redirect('login/index');
        }
    }
}

 

其它需要登录后才能操作的控制器

这些控制器需继承Admin控制器
这里只是以Index控制器来说明

 

<?php
namespace app\admin\controller;


class Index extends Admin
{
    public function index()
    {
        $this->display();
    }
}
