Se um cliente tentar enviar alguns **cabeçalhos extra**, eles irão receber uma resposta de **erro**.

Por exemplo, se o cliente tentar enviar um cabeçalho `tool` com o valor `plumbus`, ele irá receber uma resposta de **erro** informando que o parâmetro do cabeçalho `tool` não é permitido:

Puedes usar la configuración del modelo de Pydantic para `forbid` cualquier campo `extra`:

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

Si un cliente intenta enviar datos extra, recibirá un response de **error**.

Por ejemplo, si el cliente intenta enviar los campos de formulario:

* `username`: `Rick`
* `password`: `Portal Gun`
* `extra`: `Mr. Poopybutthole`
