Laravel Middleware Defining a Middleware
Example
To define a new middleware we have to create the middleware class:
class AuthenticationMiddleware
{
//this method will execute when the middleware will be triggered
public function handle ( $request, Closure $next )
{
if ( ! Auth::user() )
{
return redirect('login');
}
return $next($request);
}
}
Then we have to register the middleware: if the middleware should be bind to all the routes of the application, we should add it to the middleware property of app/Http/Kernel.php:
protected $middleware = [
\Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
\App\Http\Middleware\AuthenticationMiddleware::class
];
while if we only want to associate the middleware to some of the routes, we can add it to $routeMiddleware
//register the middleware as a 'route middleware' giving it the name of 'custom_auth'
protected $routeMiddleware = [
'custom_auth' => \App\Http\Middleware\AuthenticationMiddleware::class
];
and then bind it to the single routes like this:
//bind the middleware to the admin_page route, so that it will be executed for that route
Route::get('admin_page', 'AdminController@index')->middleware('custom_auth');
