README

Library and middleware enabling cross-origin resource sharing for your http-{foundation,kernel} using application. It attempts to implement the W3C Recommendation for cross-origin resource sharing.

Build status:

Installation

Require asm89/stack-cors using composer.

Usage

This package can be used as a library or as stack middleware.

Options

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.

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

Example: using the library

<?php

use Asm89\Stack\CorsService;

$cors = new CorsService([
    'allowedHeaders'         => ['x-allowed-header', 'x-other-allowed-header'],
    'allowedMethods'         => ['DELETE', 'GET', 'POST', 'PUT'],
    'allowedOrigins'         => ['http://localhost'],
    'allowedOriginsPatterns' => ['/localhost:\d/'],
    '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);

Example: using the stack middleware

<?php

use Asm89\Stack\Cors;

$app = new Cors($app, [
    // you can use ['*'] to allow any headers
    'allowedHeaders'      => ['x-allowed-header', 'x-other-allowed-header'],
    // you can use ['*'] to allow any methods
    'allowedMethods'      => ['DELETE', 'GET', 'POST', 'PUT'],
    // you can use ['*'] to allow requests from any origin
    'allowedOrigins'      => ['localhost'],
    // you can enter regexes that are matched to the origin request header
    'allowedOriginsPatterns' => ['/localhost:\d/'],
    'exposedHeaders'      => false,
    'maxAge'              => false,
    'supportsCredentials' => false,
]);
