Middleware to implement Cross-Origin Resource Sharing (CORS) using [neomerx/cors-psr7](https://github.com/neomerx/cors-psr7).

Requirements
------------

[](#requirements)

- PHP >= 7.2
- A [PSR-7 http library](https://github.com/middlewares/awesome-psr15-middlewares#psr-7-implementations)
- A [PSR-15 middleware dispatcher](https://github.com/middlewares/awesome-psr15-middlewares#dispatcher)

Installation
------------

[](#installation)

This package is installable and autoloadable via Composer as [middlewares/cors](https://packagist.org/packages/middlewares/cors).

```
composer require middlewares/cors
```

Example
-------

[](#example)

```
use Neomerx\Cors\Strategies\Settings;
use Neomerx\Cors\Analyzer;

$settings = new Settings();
$settings->setServerOrigin('http', 'example.com', 123);

$analyzer = Analyzer::instance($settings);

$dispatcher = new Dispatcher([
    new Middlewares\Cors($analyzer)
]);

$response = $dispatcher->dispatch(new ServerRequest());
```

Usage
-----

[](#usage)

You have to provide a `Neomerx\Cors\Contracts\AnalyzerInterface` to the constructor. See [neomerx/cors-psr7](https://github.com/neomerx/cors-psr7) for more info. Optionally, you can provide a `Psr\Http\Message\ResponseFactoryInterface` as the second argument to create the responses. If it's not defined, [Middleware\\Utils\\Factory](https://github.com/middlewares/utils#factory) will be used to detect it automatically.

```
$analyzer = Analyzer::instance($settings);
$responseFactory = new MyOwnResponseFactory();

$cors = new Middlewares\Cors($analyzer, $responseFactory);
```
