RoutingMiddleware

Solo\Application\RoutingMiddleware matches the request against the router, stores the route in request attributes and runs the route's own middleware before passing the request on. See Routing for usage.

final readonly class RoutingMiddleware implements Psr\Http\Server\MiddlewareInterface

Application registers it in the container with $app->router, so list it as RoutingMiddleware::class.

__construct()

public function __construct(
    Solo\Router\Router $router,
    ContainerInterface $container,
)

$router is the built router to match against. $container resolves route middleware given as IDs.

process()

public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface

1. Resolves the request method and path with Router::resolve(). The path is the one the client sent, with a leading slash and with only percent-encoded non-ASCII bytes decoded.

2. Throws RouteNotFoundException if no route matches, or MethodNotAllowedException with the allowed methods if the path exists for other methods.

3. Percent-decodes the parameters and throws InvalidRouteParameterException if one contains a control character (\x00–\x1F, \x7F).

4. Adds the request attributes:

   Attribute	Value
   RequestAttribute::HANDLER	$route->handler
   RequestAttribute::PARAMS	The decoded parameters, array<string, string>
   RequestAttribute::ROUTE_NAME	$route->name, or null
   RequestAttribute::ROUTE_ATTRIBUTES	$route->attributes

5. Runs $route->middlewares — group middleware from the outermost group in, then the route's own — in a MiddlewarePipeline whose final handler is $handler, and returns its response.

Throws the routing exceptions above, and whatever the route middleware or the rest of the pipeline throw.
