Ajax - Cross-Origin Request Blocked in Larave?

By Hardik Savani September 5, 2020 Category : Laravel jQuery Angular Ajax

When i was working on my laravel 5 project and i was making backend API, i created successfully but when front-end developer call API which i made. It's return like: "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://learnl52.hd/register. (Reason: CORS header 'Access-Control-Allow-Origin' missing)." and i did try to how to solve this issue. I did also try with jquery and angularjs from backend but result nothing always.

At last i did found how to solve this issue, i made one middleware that allows to Cross-Origin Request in your laravel application. so let's create new middleware :

Create Middleware

php artisan make:middleware CORS

On now you can check on Middleware(app/Http/Middleware) directory, you can find CORS.php file and put bellow code on that file.


namespace App\Http\Middleware;

use Closure;

class CORS


public function handle($request, Closure $next)


header('Access-Control-Allow-Origin: *');

$headers = [

'Access-Control-Allow-Methods'=> 'POST, GET, OPTIONS, PUT, DELETE',

'Access-Control-Allow-Headers'=> 'Content-Type, X-Auth-Token, Origin'


if($request->getMethod() == "OPTIONS") {

return Response::make('OK', 200, $headers);


$response = $next($request);

foreach($headers as $key => $value)

$response->header($key, $value);

return $response;



Ok, now register new created middleware on Kernel.php(app/Http/Kernel.php) file and append following line.


namespace App\Http;

use Illuminate\Foundation\Http\Kernel as HttpKernel;

class Kernel extends HttpKernel




protected $routeMiddleware = [


'cors' => \App\Http\Middleware\CORS::class,



Now we are ready to use 'cors' middleware on route file so, use following way:


Route::group(['middleware' => ['api','cors'],'prefix' => 'api'], function () {

Route::post('register', 'APIController@register');

Route::post('login', 'APIController@login');
