Y todas estas miles de *path operations* pueden ser tan pequeñas como 3 líneas:

## Resumen { #recap }

Ahora puedes obtener el usuario actual directamente en tu *path operation function*.

Ya estamos a mitad de camino.

## Variável de Ambiente `PATH` { #path-environment-variable }

Existe uma variável de ambiente **especial** chamada **`PATH`** que é usada pelos sistemas operacionais (Linux, macOS, Windows) para encontrar programas para executar.

### `FileResponse` { #fileresponse }

Transmite un archivo asincrónicamente como response.

Toma un conjunto diferente de argumentos para crear un instance que los otros tipos de response:

* `path` - La path del archivo para el archivo a transmitir.

### Bereitstellung des `root_path` { #providing-the-root-path }

Um dies zu erreichen, können Sie die Kommandozeilenoption `--root-path` wie folgt verwenden:

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1
