## Use `StaticFiles` { #use-staticfiles }

* Import `StaticFiles`.
* "Mount" a `StaticFiles()` instance in a specific path.

{* ../../docs_src/static_files/tutorial001_py39.py hl[2,6] *}

/// note | Technical Details

You could also use `from starlette.staticfiles import StaticFiles`.

## Usa `StaticFiles` { #use-staticfiles }

* Importa `StaticFiles`.
* "Monta" una instance de `StaticFiles()` en un path específico.

{* ../../docs_src/static_files/tutorial001_py39.py hl[2,6] *}

/// note | Detalles Técnicos

También podrías usar `from starlette.staticfiles import StaticFiles`.

And then you can set the `status_code` in that *temporal* response object.

{* ../../docs_src/response_change_status_code/tutorial001_py39.py hl[1,9,12] *}

And then you can return any object you need, as you normally would (a `dict`, a database model, etc).

@pytest.fixture(

    params=[

def get_client(request: pytest.FixtureRequest) -> TestClient:
    mod = importlib.import_module(
        f"docs_src.path_operation_configuration.{request.param}"

Wenn Sie in Ihrer Funktion andere Parameter deklarieren, die nicht Teil der Pfad-Parameter sind, dann werden diese automatisch als „Query“-Parameter interpretiert.

{* ../../docs_src/query_params/tutorial001_py39.py hl[9] *}

Die <abbr title="Abfrage">Query</abbr> ist die Menge von Schlüssel-Wert-Paaren, die nach dem `?` in einer URL folgen und durch `&`-Zeichen getrennt sind.

Zum Beispiel sind in der URL:

```

Представим, что вы хотите получить IP-адрес/хост клиента внутри вашей *функции-обработчика пути*.

Для этого нужно обратиться к запросу напрямую.

{* ../../docs_src/using_request_directly/tutorial001_py39.py hl[1,7:8] *}

Если объявить параметр *функции-обработчика пути* с типом `Request`, **FastAPI** поймёт, что нужно передать объект `Request` в этот параметр.

/// tip | Совет

E então você pode definir o `status_code` neste objeto de retorno temporal.

{* ../../docs_src/response_change_status_code/tutorial001_py39.py hl[1,9,12] *}

E então você pode retornar qualquer objeto que você precise, como você faria normalmente (um `dict`, um modelo de banco de dados, etc.).

Let's imagine you want to get the client's IP address/host inside of your *path operation function*.

For that you need to access the request directly.

{* ../../docs_src/using_request_directly/tutorial001_py39.py hl[1,7:8] *}

By declaring a *path operation function* parameter with the type being the `Request` **FastAPI** will know to pass the `Request` in that parameter.
