Getting Started with ArrayConfiguration

Start off using CORS Middleware with a CORS Configuration represented by an array. If you already have a CORS configuration represented as an array or can't store your configuration as PHP code this might be the implementation for you.

Using ArrayConfiguration is as simple as providing an array to the constructor with all of your configuration values.


use Cspray\Labrador\Http\Cors\ArrayConfiguration;
use Cspray\Labrador\Http\Cors\SimpleConfigurationLoader;
use Cspray\Labrador\Http\Cors\CorsMiddleware;

$arrayConfig = [
    'origins' => [''],
    'allowed_methods' => ['GET', 'POST', 'PUT'],
    'max_age' => 8600,
    'allowed_headers' => ['X-Request-Headers'],
    'exposable_headers' => ['X-Response-Headers'],
    'allow_credentials' => false
$config = new ArrayConfiguration($arrayConfig);
$loader = new SimpleConfigurationLoader($config);
$middleware = new CorsMiddleware($loader);

The only key required is origins, otherwise the corresponding CORS header will not be set if there are no values provided. Once you have the CorsMiddleware instantiated you can attach it to your http-server router as appropriate for your application stack. If you are running Labrador HTTP you would attach this to the Application directly if you'd like to handle CORS requests similarly for all routes. You also have the option to attach this Middleware to a specific route or group of routes.

This implementation does not make stringent type checks against values passed to constructor. If the values provided are not a correct type you will encounter runtime errors when a request is processed. If type safety is important to you please check Getting Started with ConfigurationBuilder.
