# 1.通过artisan命令创建登录校验中间件
```
php artisan make:middleware AdminLogin
```
# 2.通过session驱动来判断用户是否登录
```
<?php
namespace App\Http\Middleware;
use Closure;
class AdminLogin
{
public function handle($request, Closure $next)
{
if (!session()->has('admin')){
return redirect('login');
}
return $next($request);
}
}
```
# 3.打开kernal.php注册一下中间件
```
protected $routeMiddleware = [
'login' => \App\Http\Middleware\AdminLogin::class,
];
```
# 4.配置一下路由
```
Route::namespace('Admin')->group(function () {
Route::group(['middleware' => 'login'], function () {
Route::match(['GET'], '/index', 'Home@index');
Route::match(['POST'], '/logout', 'Home@logout');
});
});
```
