If you do that, then you can return the URL directly from your *path operation* function.

In this case, the `status_code` used will be the default one for the `RedirectResponse`, which is `307`.

---

You can also use the `status_code` parameter combined with the `response_class` parameter:

{* ../../docs_src/custom_response/tutorial006c_py39.py hl[2,7,9] *}

---

또는 `response_class` 매개변수에서 사용할 수도 있습니다:


{* ../../docs_src/custom_response/tutorial006b.py hl[2,7,9] *}

이 경우, *경로 작업* 함수에서 URL을 직접 반환할 수 있습니다.

이 경우, 사용되는 `status_code`는 `RedirectResponse`의 기본값인 `307` 입니다.

---

`status_code` 매개변수를 `response_class` 매개변수와 함께 사용할 수도 있습니다:

{* ../../docs_src/custom_response/tutorial006c.py hl[2,7,9] *}

### `StreamingResponse`

## 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 headers).

And then you can set the `status_code` in that *temporal* response object.

{* ../../docs_src/response_change_status_code/tutorial001_py39.py hl[1,9,12] *}

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