HTTP Middleware


HTTP middleware provide a convenient mechanism for filtering HTTP requests entering your application. For example, Laravel includes a middleware that verifies the user of your application is authenticated. If the user is not authenticated, the middleware will redirect the user to the login screen. However, if the user is authenticated, the middleware will allow the request to proceed further into the application.

Of course, middleware can be written to perform a variety of tasks besides authentication. A CORS middleware might be responsible for adding the proper headers to all responses leaving your application. A logging middleware might log all incoming requests to your application.

There are several middleware included in the Laravel framework, including middleware for maintenance, authentication, CSRF protection, and more. All of these middleware are located in the app/Http/Middleware directory.

Defining Middleware

To create a new route filter, use the make:middleware Artisan command:

php artisan make:middleware OldMiddleware

This command will place a new OldMiddleware class within your app/Http/Middleware directory. In this middleware, we will only allow access to the route if the supplied age is greater than 200. Otherwise, we will redirect the users back to the "home" URI.

<?php namespace App\Http\Middleware;

class OldMiddleware {

     * Run the request filter.
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
    public function handle($request, Closure $next)
        if ($request->input('age') < 200)
            return redirect('home');

        return $next($request);


As you can see, if the given age is less than 200, the middleware will return an HTTP redirect to the client; otherwise, the request will be passed further into the application. To pass the request deeper into the application (allowing the middleware to "pass"), simply call the $next callback with the $request.

It's best to envision middleware as a series of "layers" HTTP requests must pass through before they hit your application. Each layer can examine the request and even reject it entirely.

Registering Middleware

Global Middleware

If you want a middleware to be run during every HTTP request to your application, simply list the middleware class in the $middleware property of your app/Http/Kernel.php class.

Assigning Middleware To Routes

If you would like to assign middleware to specific routes, you should first assign the middleware a short-hand key in your app/Http/Kernel.php file. By default, the $middleware property of this class contains entries for the middleware included with Laravel. To add your own, simply append it to this list and assign it a key of your choosing.

Once the middleware has been defined in the HTTP kernel, you may use the middleware key in the route options array:

Route::get('admin/profile', ['middleware' => 'auth', function()
