Example: using the library

<?php

use Fruitcake\Cors\CorsService;

$cors = new CorsService([
    'allowedHeaders'         => ['x-allowed-header', 'x-other-allowed-header'],
    'allowedMethods'         => ['DELETE', 'GET', 'POST', 'PUT'],
    'allowedOrigins'         => ['http://localhost', 'https://*.example.com'],
    'allowedOriginsPatterns' => ['/localhost:\d/'],
    'exposedHeaders'         => ['Content-Encoding'],
    'maxAge'                 => 0,
    'supportsCredentials'    => false,
]);

$cors->addActualRequestHeaders(Response $response, $origin);
$cors->handlePreflightRequest(Request $request);
$cors->isActualRequestAllowed(Request $request);
$cors->isCorsRequest(Request $request);
$cors->isPreflightRequest(Request $request);

Options

Option	Description	Default value
allowedMethods	Matches the request method.	[]
allowedOrigins	Matches the request origin.	[]
allowedOriginsPatterns	Matches the request origin with preg_match.	[]
allowedHeaders	Sets the Access-Control-Allow-Headers response header.	[]
exposedHeaders	Sets the Access-Control-Expose-Headers response header.	[]
maxAge	Sets the Access-Control-Max-Age response header.	0
supportsCredentials	Sets the Access-Control-Allow-Credentials header.	false

The allowedMethods and allowedHeaders options are case-insensitive.

You don’t need to provide both allowedOrigins and allowedOriginsPatterns. If one of the strings passed matches, it is considered a valid origin. A wildcard in allowedOrigins will be converted to a pattern.

If [’*’] is provided to allowedMethods, allowedOrigins or allowedHeaders all methods/origins/headers are allowed.
