README
Inline stack middleware.
Enables the usage of callables as stack middlewares.
Example
Here is a contrived example showing how a callable can be used to easily act as a stack middleware for a silex application:
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpKernel\HttpKernelInterface;
$app = new Silex\Application();
$app->get('/', function (Request $request) {
if ('success' === $request->attributes->get('callable_middleware')) {
return new Response('SUCCESS');
}
return new Response('FAILED', 500);
});
$inlineMiddleware = function(
HttpKernelInterface $app,
Request $request,
$type = HttpKernelInterface::MASTER_REQUEST,
$catch = true
) {
$request->attributes->set('callable_middleware', 'success');
$response = $app->handle($request, $type, $catch);
$response->setContent('['.$response->getContent().']');
return $response;
};
$stack = (new Stack\Builder())
->push('Stack\Inline', $inlineMiddleware);
$app = $stack->resolve($app);
Usage
The method signature for the callable is similar to HttpKernelInterface::handle
except that it requires an HttpKernelInterface
instance as its first argument.
A simple passthru inline middleware would look like this:
$app = new Stack\Inline($app, function(
HttpKernelInterface $app,
Request $request,
$type = HttpKernelInterface::MASTER_REQUEST,
$catch = true
) {
return $app->handle($request, $type, $catch);
});
