Для таких случаев вы можете использовать параметр `Response`.

## Использование параметра `Response` { #use-a-response-parameter }

Вы можете объявить параметр типа `Response` в вашей *функции обработки пути* (как и для cookies и HTTP-заголовков).

И затем вы можете установить `status_code` в этом *временном* объекте ответа.

# `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
```
