## 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.py hl[1,9,12] *}

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

## Использование параметра `Response`

Вы можете объявить параметр типа `Response` в вашей *функции обработки пути* (так же как для cookies и headers).

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

{* ../../docs_src/response_change_status_code/tutorial001.py hl[1,9,12] *}

После этого вы можете вернуть любой объект, который вам нужен, как обычно (`dict`, модель базы данных и т.д.).

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.py hl[2,7,9] *}

To achieve that, import `JSONResponse`, and return your content there directly, setting the `status_code` that you want:

{* ../../docs_src/additional_status_codes/tutorial001_an_py310.py hl[4,25] *}

/// warning

When you return a `Response` directly, like in the example above, it will be returned directly.

Notice that these parameters are passed directly to the *path operation decorator*, not to your *path operation function*.

///

## Response Status Code { #response-status-code }

You can define the (HTTP) `status_code` to be used in the response of your *path operation*.

You can pass directly the `int` code, like `404`.

But if you don't remember what each number code is for, you can use the shortcut constants in `status`:

Чтобы реализовать это, импортируйте `JSONResponse` и возвращайте ваш контент напрямую, устанавливая нужный `status_code`:

{* ../../docs_src/additional_status_codes/tutorial001_an_py310.py hl[4,25] *}

/// warning | Внимание

Когда вы возвращаете объект `Response` напрямую, как в примере выше, он будет возвращён как есть.

///

## Combining information { #combining-information }

You can also combine response information from multiple places, including the `response_model`, `status_code`, and `responses` parameters.

{* ../../docs_src/path_operation_advanced_configuration/tutorial004.py hl[19:29] *}

## Additional Responses { #additional-responses }

You probably have seen how to declare the `response_model` and `status_code` for a *path operation*.

That defines the metadata about the main response of a *path operation*.

You can also declare additional responses with their models, status codes, etc.

    public void test_statusCode_variousHttpCodes() {
        // Test with various HTTP status codes
        int[] statusCodes = { 200, 201, 400, 401, 403, 404, 500, 502, 503 };

        for (int statusCode : statusCodes) {
            WebApiException exception = new WebApiException(statusCode, "Test message");
            assertEquals(statusCode, exception.getStatusCode());
        }
    }

    public void test_statusCode_negativeValue() {
