<?php

namespace app\admin\controller;

use think\Controller;

class Login extends Controller
{
    public function index()
    {
        //加载视图文件
        return $this->fetch();
    }

    //验证用户名密码
    public function check()
    {
        //得到提交的表单信息
        $data = input('post.');
        dump($data);
        //验证码判断
        if (!captcha_check($data['code'])) {
            $this->error('验证码不正确！');
