Mas você ainda quer ser capaz de filtrar e converter o dado que você retornará com um `response_model`.

Para estes casos, você pode utilizar um parâmetro `Response`.

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

Você pode declarar um parâmetro do tipo `Response` em sua *função de operação de rota* (assim como você pode fazer para cookies e headers).

# `HTTPConnection` class

When you want to define dependencies that should be compatible with both HTTP and WebSockets, you can define a parameter that takes an `HTTPConnection` instead of a `Request` or a `WebSocket`.

You can import it from `fastapi.requests`:

```python
from fastapi.requests import HTTPConnection
```

Um eine Middleware zu erstellen, verwenden Sie den Dekorator `@app.middleware("http")` über einer Funktion.

Die Middleware-Funktion erhält:

* Den `request`.
* Eine Funktion `call_next`, die den `request` als Parameter erhält.
    * Diese Funktion gibt den `request` an die entsprechende *Pfadoperation* weiter.
    * Dann gibt es die von der entsprechenden *Pfadoperation* generierte `response` zurück.

 * users should prefer the {@link Network} interface.
