Authorize a form request only if it an ajax call

Question

I have a form that i want to authorize only if the call was made by ajax, so i tried

....
//MyRequest authorize function
public function authorize()
{
    return $this->ajax();
}

But after when i do the ajax call, in the console it shown "This action is unauthorized.", so how can i detect if the call was an ajax and return true, else return false?

This is a job for middlewares.

php artisan make:middleware IsAjaxRequest

In app/Http/Middleware/IsAjaxRequest.php

<?php

namespace App\Http\Middleware;

class IsAjaxRequest
{
    public function handle($request, \Closure $next)
    {
        // Check if the route is an ajax request only route
        if (!$request->ajax()) {
             abort(405, 'Unauthorized action.');
        }

        return $next($request);
    }
}

Don't forget to also register your middleware in app/Http/Kernel.php by adding the following in the $routeMiddleware array.

'ajax' => \App\Http\Middleware\IsAjaxRequest::class

Then you can add it to any route handling an Ajax call

Route::get('users', 'UserController@method')->middleware('ajax');
