创建中间件命令
php artisan make:middleware CheckLogin
执行完以上命令会在app/Http/Middleware目录下创建一个新的中间件类CheckLogin.php。
创建完以后还需要注册中间件在app/Http/Kernel.php中：
protected $routeMiddleware = [
\'auth\' => \Illuminate\Auth\Middleware\Authenticate::class,
\'auth.basic\' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
\'bindings\' => \Illuminate\Routing\Middleware\SubstituteBindings::class,
\'can\' => \Illuminate\Auth\Middleware\Authorize::class,
\'guest\' => \App\Http\Middleware\RedirectIfAuthenticated::class,
\'throttle\' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
//这就是新注册的中间件
\'checklogin\' => \App\Http\Middleware\CheckLogin::class, ];
可以在刚创建的中间件里写验证如下：
<?php
namespace App\Http\Middleware;
use Closure;
use Illuminate\Support\Facades\Session;
class CheckLogin{
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle($request, Closure $next)
{
$userid = Session::get(\'_userid\');
$login_sts = Session::get(\'_login_sts\');
if (empty($userid) || empty($login_sts)){
return response()->view(\'admin/login\');
}
return $next($request);
}
}
接着就是怎么使用中间件功能了
Route::group([\'namespace\'=>\'Admin\',\'middleware\'=>\'checklogin\'],function (){
Route::get(\'admins\',\'IndexController@index\');
Route::get(\'logout\',\'IndexController@logout\');});
这里直接使用的是路由群组，只要把路由放在群组之中都会经过这个验证，[‘namespace’=>’Admin’]是命名空间，[‘middleware’=>’checklogin’]这就是中间件验证，之前注册时注册名为checklogin，所以middleware后直接写checklogin就可以了
