Laravel 5.1 API Enable Cors

Question

I've looked for some ways to enable cors on laravel 5.1 specifically, I have found some libs like:

https://github.com/neomerx/cors-illuminate

https://github.com/barryvdh/laravel-cors

but none of them has a implementation tutorial specifically to Laravel 5.1, I tried to config but It doesn't work.

If someone already implemented CORS on laravel 5.1 I would be grateful for the help...

Here is my CORS middleware:

<?php namespace App\Http\Middleware;  use Closure;  class CORS {      /**      * Handle an incoming request.      *      * @param  \Illuminate\Http\Request  $request      * @param  \Closure  $next      * @return mixed      */     public function handle($request, Closure $next)     {          header("Access-Control-Allow-Origin: *");          // ALLOW OPTIONS METHOD         $headers = [             'Access-Control-Allow-Methods'=> 'POST, GET, OPTIONS, PUT, DELETE',             'Access-Control-Allow-Headers'=> 'Content-Type, X-Auth-Token, Origin'         ];         if($request->getMethod() == "OPTIONS") {             // The client-side application can set only headers allowed in Access-Control-Allow-Headers             return Response::make('OK', 200, $headers);         }          $response = $next($request);         foreach($headers as $key => $value)             $response->header($key, $value);         return $response;     }  } 

To use CORS middleware you have to register it first in your app\Http\Kernel.php file like this:

protected $routeMiddleware = [         //other middlewares         'cors' => 'App\Http\Middleware\CORS',     ]; 

Then you can use it in your routes

Route::get('example', array('middleware' => 'cors', 'uses' => 'ExampleController@dummy')); 

Edit: In Laravel ^8.0 you have to import the namespace of the controller and use the class like this:

use App\Http\Controllers\ExampleController;  Route::get('example', [ExampleController::class, 'dummy'])->middleware('cors');

I always use an easy method. Just add below lines to \public\index.php file. You don't have to use a middleware I think.

header('Access-Control-Allow-Origin: *');   header('Access-Control-Allow-Methods: GET, PUT, POST, DELETE, OPTIONS');
