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

<?phpnamespace 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');
}
}}

、、、、、、、、表单页面的退出登录<li><a tabindex="-1" href="/goods/login/loginOut">安全退出</a></li>

<?phpnamespace 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'); }}
