А затем — как работать с [CORS с помощью `CORSMiddleware`](../tutorial/cors.md).

В этом разделе посмотрим, как использовать другие middleware.

## Добавление ASGI middleware { #adding-asgi-middlewares }

Так как **FastAPI** основан на Starlette и реализует спецификацию <abbr title="Asynchronous Server Gateway Interface – Асинхронный шлюзовой интерфейс сервера">ASGI</abbr>, вы можете использовать любое ASGI middleware.

		if err = objectKey.Unseal(key, sealedKey, crypto.SSEC.String(), bucket, object); err != nil {
			return nil, err
		}
		return objectKey[:], nil
	default:
		return nil, errObjectTampered
	}
}

// Adding support for reader based interface

// DecryptRequestWithSequenceNumberR - same as
// DecryptRequestWithSequenceNumber but with a reader

			// Object info is the same in all disks, so we can pick
			// the first meta from online disk
			fi = partsMetadata[i]
			break
		}
	}

	// we are adding a new version to this object under the namespace lock, so this is the latest version.
	fi.IsLatest = true

	// Success, return object info.
