path operation 関数の引数として `Request` 型のパラメータを宣言すると、**FastAPI** はその引数に `Request` を渡します。

/// tip | 豆知識

この例では、`Request` 型の引数に加えて、パスパラメータも宣言しています。

そのため、パスパラメータは取り出され、検証され、指定した型に変換され、OpenAPI で注釈（ドキュメント化）されます。

同様に、通常どおり任意の他のパラメータを宣言しつつ、追加で `Request` も受け取れます。

Sie können auch `from starlette.requests import Request` verwenden.

El middleware responde a dos tipos particulares de request HTTP...

### Requests de preflight CORS { #cors-preflight-requests }

Estos son cualquier request `OPTIONS` con headers `Origin` y `Access-Control-Request-Method`.

En este caso, el middleware interceptará el request entrante y responderá con los headers CORS adecuados, y un response `200` o `400` con fines informativos.

### Requests simples { #simple-requests }

Algunos casos de uso incluyen:

* Convertir cuerpos de requests no-JSON a JSON (por ejemplo, [`msgpack`](https://msgpack.org/index.html)).
* Descomprimir cuerpos de requests comprimidos con gzip.
* Registrar automáticamente todos los request bodies.

## Manejo de codificaciones personalizadas de request body { #handling-custom-request-body-encodings }

Veamos cómo hacer uso de una subclase personalizada de `Request` para descomprimir requests gzip.

- Kube-apiserver: Added Alpha features to allow API server authz to check the context of requests:
  - The `AuthorizeWithSelectors` feature gate enables including field and label selector information from requests in webhook authorization calls.

public class RankFusionProcessor implements AutoCloseable {

    private static final Logger logger = LogManager.getLogger(RankFusionProcessor.class);

    /** Thread-safe list of rank fusion searchers available for processing search requests */
    protected final List<RankFusionSearcher> searchers = new CopyOnWriteArrayList<>();

    /** Executor service for concurrent search operations across multiple searchers */
    protected ExecutorService executorService;

 * DFS referrals. (E.g. a resource with a DFS root's parent will still point to the DFS root not the share it's actually
 * located in).
 * - share + uncpath within it: This is the relevant information for most SMB requests. Both are adjusted by DFS
 * referrals. Nested resources will inherit the information already resolved by the parent resource.
 *
 * Invariant:
