In case Web Server throws CORS errors when trying to access API. We add a filter that adds header with CORS info to define which kind of HTTP are allowed from foreign source.

Create CorsFilter.php

php spark make:filter Cors --suffix

Add to before method:

public function before(RequestInterface $request, $arguments=null)
{
	header("Access-Control-Allow-Origin: *");
	header("Access-Control-Allow-Headers: Authorization, Content-Type, Accept, API-KEY");
	header("Access-Control-Allow-Methods: GET, POST, PUT, DELETE, PATCH");
}

Add in app/Config/Filters.php: ! !
