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.

Note: This is a standalone fork of https://github.com/asm89/stack-cors and is compatible with the options for CorsService.

Installation

Require fruitcake/php-cors using composer.

Usage

This package can be used as a library. You can use it in your framework using:

• Stack middleware: https://github.com/asm89/stack-cors
• Laravel: https://github.com/fruitcake/laravel-cors

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. A wildcard in allowedOrigins will be converted to a pattern.

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

Note: Allowing a single static origin will improve cacheability.

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);
