Ajax – Cross-Origin Request Blocked in Larave?

In this post we will give you information about Ajax – Cross-Origin Request Blocked in Larave?. Hear we will give you detail about Ajax – Cross-Origin Request Blocked in Larave?And how to use it also give you demo for it if it is necessary.

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 . (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.

app/Http/Middleware/CORS.php

namespace AppHttpMiddleware;

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.

app/Http/Kernel.php

namespace AppHttp;

use IlluminateFoundationHttpKernel as HttpKernel;



class Kernel extends HttpKernel

{

	...

	...



    protected $routeMiddleware = [

        ...

        'cors' => AppHttpMiddlewareCORS::class,

    ];

}


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

app/Http/routes.php

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

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

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

});
