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`.

Você pode utilizar `Security` para declarar dependências (assim como `Depends`), porém o `Security` também recebe o parâmetros `scopes` com uma lista de escopos (strings).

## Criar um middleware

Para criar um middleware, use o decorador `@app.middleware("http")` logo acima de uma função.

A função middleware recebe:

* A `request`.
* Uma função `call_next` que receberá o `request` como um parâmetro.
    * Esta função passará a `request` para a *operação de rota* correspondente.

Luego, tras bastidores, pondría esos datos compatibles con JSON (por ejemplo, un `dict`) dentro de una `JSONResponse` que se usaría para enviar la respuesta al cliente.

Pero puedes devolver una `JSONResponse` directamente de tu *operación de path*.

Esto puede ser útil, por ejemplo, para devolver cookies o headers personalizados.

## Devolver una `Response`
