Installation

Require asm89/stack-cors using composer.

Usage

Stack middleware:

<?php

use Asm89\Stack\Cors;

$app = new Cors($app, array(
    // you can use array('*') to allow any headers
    'allowedHeaders'      => array('x-allowed-header', 'x-other-allowed-header'),
    // you can use array('*') to allow any methods
    'allowedMethods'      => array('DELETE', 'GET', 'POST', 'PUT'),
    // you can use array('*') to allow requests from any origin
    'allowedOrigins'      => array('localhost'),
    'exposedHeaders'      => false,
    'maxAge'              => false,
    'supportsCredentials' => false,
));

Or use the library:

<?php

use Asm89\Stack\CorsService;

$cors = new CorsService(array(
    'allowedHeaders'      => array('x-allowed-header', 'x-other-allowed-header'),
    'allowedMethods'      => array('DELETE', 'GET', 'POST', 'PUT'),
    'allowedOrigins'      => array('localhost'),
    'exposedHeaders'      => false,
    'maxAge'              => false,
    'supportsCredentials' => false,
));

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