# ➰ Request Callback
[](https://codecov.io/gh/leocavalcante/request-callback)
[](https://shepherd.dev/github/leocavalcante/request-callback)
[Swoole](https://www.swoole.co.uk/) request callback for [PSR](https://www.php-fig.org/psr/) compliant handlers.
## Install
```bash
composer require leocavalcante/request-callback
```
## Usage
Simply create a callback that decorates a [`RequestHandlerInterface`](https://www.php-fig.org/psr/psr-15/#11-request-handlers) and pass as a listener to the [`onRequest`](https://www.swoole.co.uk/docs/modules/swoole-http-server-on-request) event of the [`Swoole\Http\Server`](https://www.swoole.co.uk/docs/modules/swoole-http-server-doc).
```php
use Swoole\Http\RequestCallback;
$callback = new RequestCallback(\Psr\Http\Server\RequestHandlerInterface);
```
### Example
#### Hello, World!
```php
use Laminas\Diactoros\Response\TextResponse;
use Psr\Http\Message\{ResponseInterface, ServerRequestInterface};
use Psr\Http\Server\RequestHandlerInterface;
use Swoole\Http\{RequestCallback, Server};
$server = new Server('localhost', 9501);
$server->on('request', new RequestCallback(new class implements RequestHandlerInterface {
public function handle(ServerRequestInterface $request): ResponseInterface
{
return new TextResponse(sprintf('Hello, %s!', $request->getQueryParams()['name'] ?? 'World'));
}
}));
$server->start();
```
To help you with the boilerplate, you can use the `RequestCallback::fromCallable(callable)` factory method:
```php
$server->on('request', RequestCallback::fromCallable(static function (ServerRequestInterface $request): ResponseInterface {
return new TextResponse(sprintf('Hello, %s!', $request->getQueryParams()['name'] ?? 'World'));
}));
```
If you are like me and want even more sugar, use the `request_callback(RequestHandlerInterface|callable)` function:
```php
$server->on('request', request_callback(
static fn(ServerRequestInterface $request): ResponseInterface =>
new TextResponse(sprintf('Hello, %s!', $request->getQueryParams()['name'] ?? 'World')))
);
```
You can pass either a `RequestHandlerInterface` or a `callable`, it will figure out.
#### Middleware
```php
use Laminas\Diactoros\Response\JsonResponse;
use Laminas\Stratigility\MiddlewarePipe;
use Psr\Http\Message\{ResponseInterface, ServerRequestInterface};
use Psr\Http\Server\RequestHandlerInterface;
use Swoole\Http\{RequestCallback, Server};
use function Laminas\Stratigility\middleware;
$app = new MiddlewarePipe();
$app->pipe(middleware(static function (ServerRequestInterface $request, RequestHandlerInterface $next): ResponseInterface {
$user = $request->getQueryParams()['user'] ?? null;
if ($user === null) {
return new JsonResponse(['error' => true, 'message' => 'Unauthorized'], 401);
}
return $next
->handle($request->withAttribute('user', $user))
->withAddedHeader('X-Foo', 'Bar');
}));
$app->pipe(middleware(static function (ServerRequestInterface $request, RequestHandlerInterface $next): ResponseInterface {
return new JsonResponse(['message' => sprintf('Hello, %s!', $request->getAttribute('user'))]);
}));
$server = new Server('0.0.0.0', 9501);
$server->on('request', new RequestCallback($app));
$server->start();
```
