* Implementa y utiliza herramientas criptográficas bien conocidas, como Passlib y JWT tokens, etc.
* Añade controles de permisos más detallados con OAuth2 scopes donde sea necesario.
* ...etc.

No obstante, podrías tener un caso de uso muy específico donde realmente necesites desactivar la documentación de la API para algún entorno (por ejemplo, para producción) o dependiendo de configuraciones de variables de entorno.

...makes the parameter optional, with a default value of `None`, the same as:


```Python
q: str | None = None
```

But the `Query` version declares it explicitly as being a query parameter.

Then, we can pass more parameters to `Query`. In this case, the `max_length` parameter that applies to strings:

```Python
q: str | None = Query(default=None, max_length=50)
```

For that you need to access the request directly.

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

/// tip

Note that in this case, we are declaring a path parameter beside the request parameter.

Você pode utilizar a configuração de modelo do Pydantic para `proibir` qualquer campo `extra`:

{* ../../docs_src/request_form_models/tutorial002_an_py39.py hl[12] *}

Caso um cliente tente enviar informações adicionais, ele receberá um retorno de **erro**.

Por exemplo, se o cliente tentar enviar os campos de formulário:

* `username`: `Rick`
* `password`: `Portal Gun`

En las siguientes secciones verás otras opciones, configuraciones y funcionalidades adicionales.

/// tip | Consejo

Las siguientes secciones **no son necesariamente "avanzadas"**.

Y es posible que para tu caso de uso, la solución esté en una de ellas.
