Nevertheless, you can still do it in **FastAPI**, using one of the internal tools from Starlette.

And the docs would still work, although not adding any documentation telling that the parameter should contain a path.

### Path convertor { #path-convertor }

Using an option directly from Starlette you can declare a *path parameter* containing a *path* using a URL like:

```
/files/{file_path:path}
```

{"item_id":3}
```

/// check | Revisa

Nota que el valor que tu función recibió (y devolvió) es `3`, como un `int` de Python, no un string `"3"`.

Entonces, con esa declaración de tipo, **FastAPI** te ofrece <abbr title="convertir el string que viene de un request HTTP en datos de Python">"parsing"</abbr> automático de request.

///

## Validación de datos { #data-validation }

Die Dokumentation würde weiterhin funktionieren, allerdings wird nicht dokumentiert werden, dass der Parameter ein Pfad sein sollte.

### Pfad-Konverter { #path-convertor }

Mittels einer Option direkt von Starlette können Sie einen *Pfad-Parameter* deklarieren, der einen Pfad enthalten soll, indem Sie eine URL wie folgt definieren:

```
/files/{file_path:path}
```
