php-laravelHow do I enable CORS in a Laravel PHP application?

To enable CORS in a Laravel PHP application, you must first modify the config/cors.php file. This file contains the configuration options for the Laravel CORS package.

You can then use the \Barryvdh\Cors\HandleCors middleware to add CORS headers to your routes. For example:

Route::middleware('\Barryvdh\Cors\HandleCors')->get('/api', function () {
    return response('Hello World', 200)
        ->header('Content-Type', 'text/plain');
});

The HandleCors middleware will add the following CORS headers to the response:

Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: *
Access-Control-Allow-Headers: *

You can also use the \Barryvdh\Cors\CorsServiceProvider service provider to configure the CORS package. This allows you to customize the CORS headers for each route, and also set the allowed origins, methods, and headers. For example:

Cors::setHeader('Access-Control-Allow-Origin', 'http://example.com');

You can find more information about configuring CORS in the Laravel CORS documentation.
