Stack/Cors

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

Option	Description	Default value
allowedMethods	Matches the request method.	array()
allowedOrigins	Matches the request origin.	array()
allowedOriginsPatterns	Matches the request origin with preg_match.	array()
allowedHeaders	Sets the Access-Control-Allow-Headers response header.	array()
exposedHeaders	Sets the Access-Control-Expose-Headers response header.	false
maxAge	Sets the Access-Control-Max-Age response header.	false
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.

If array('*') 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(array(
    'allowedHeaders'         => array('x-allowed-header', 'x-other-allowed-header'),
    'allowedMethods'         => array('DELETE', 'GET', 'POST', 'PUT'),
    'allowedOrigins'         => array('http://localhost'),
    'allowedOriginsPatterns' => array('/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, 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'),
    // you can enter regexes that are matched to the origin request header
    'allowedOriginsPatterns' => array('/localhost:\d/'),
    'exposedHeaders'      => false,
    'maxAge'              => false,
    'supportsCredentials' => false,
));
