# 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. [W3C Recommendation]: http://www.w3.org/TR/cors/ Build status:  ## Installation Require `asm89/stack-cors` using composer. ## Usage This package can be used as a library or as [stack middleware]. [stack middleware]: http://stackphp.com/ ### 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. | `false` | | `maxAge` | Sets the Access-Control-Max-Age response header.<br/>Set to `null` to omit the header/use browser default. | `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. If `['*']` is provided to _allowedMethods_, _allowedOrigins_ or _allowedHeaders_ all methods / origins / headers are allowed. If _supportsCredentials_ is `true`, you must [explicitly set](https://fetch.spec.whatwg.org/#cors-protocol-and-credentials) `allowedHeaders` for any headers which are not CORS safelisted. ### Example: using the library ```php <?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' => 600, 'supportsCredentials' => true, ]); $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 <?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' => 600, 'supportsCredentials' => false, ]); ```
