How to handle preflight request in laravel?

To handle preflight requests in Laravel, you can use middleware to intercept OPTIONS requests and handle them accordingly.

Here's a step-by-step guide on how to handle preflight requests in Laravel:

1. Create a new middleware in your Laravel application by running the following command in your terminal:

1

php artisan make:middleware HandlePreflightRequest

1. Open the newly created middleware file located at app/Http/Middleware/HandlePreflightRequest.php and add the following code to handle OPTIONS requests:

namespace AppHttpMiddleware;

use Closure;

class HandlePreflightRequest
{
    public function handle($request, Closure $next)
    {
        if ($request->isMethod('OPTIONS')) {
            return response('', 200)
                ->header('Access-Control-Allow-Methods', 'POST, GET, OPTIONS, PUT, DELETE')
                ->header('Access-Control-Allow-Headers', 'Content-Type, Authorization');
        }

        return $next($request);
    }
}

1. Register the middleware in your app/Http/Kernel.php file under the $routeMiddleware array:

protected $routeMiddleware = [
    // Other middleware entries...
    'handlePreflight' => AppHttpMiddlewareHandlePreflightRequest::class,
];

1. Apply the middleware to the routes or groups of routes that need to handle preflight requests. You can do this by adding the handlePreflight middleware to your routes in the routes/web.php file or in your controller's constructor like this:

1

3

Route::middleware('handlePreflight')->group(function () {
    // Add your routes here
});

1. Make sure that your CORS configuration in your Laravel application allows OPTIONS requests from your client application. You can set the AllowedMethods and AllowedHeaders in the config/cors.php configuration file.

With these steps, you should be able to handle preflight requests in your Laravel application and properly respond to OPTIONS requests with the appropriate headers.
