## Declare escopos em *operações de rota* e dependências { #declare-scopes-in-path-operations-and-dependencies }

Agora nós declaramos que a *operação de rota* para `/users/me/items/` exige o escopo `items`.

Para isso, nós importamos e utilizamos `Security` de `fastapi`.

# Response Headers { #response-headers }

## Use a `Response` parameter { #use-a-response-parameter }

You can declare a parameter of type `Response` in your *path operation function* (as you can do for cookies).

And then you can set headers in that *temporal* response object.

{* ../../docs_src/response_headers/tutorial002_py39.py hl[1, 7:8] *}

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