## OpenAPI レスポンスの詳細 { #more-information-about-openapi-responses }

レスポンスに正確に何を含められるかは、OpenAPI 仕様の次のセクションを参照してください:

- [OpenAPI の Responses Object](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#responses-object)、ここには `Response Object` が含まれます。

* [OpenAPI Responses Object](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#responses-object), enthält das `Response Object`.

Чтобы увидеть, что именно можно включать в ответы, посмотрите эти разделы спецификации OpenAPI:

* [Объект Responses OpenAPI](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#responses-object), он включает `Response Object`.

Ви можете оголосити `response_model`, використовуючи типовий код статусу `200` (або власний за потреби), а потім оголосити додаткову інформацію для цієї ж відповіді в `responses`, безпосередньо в схемі OpenAPI.

**FastAPI** збереже додаткову інформацію з `responses` і поєднає її зі Схемою JSON з вашої моделі.

     * Sets the fields that are allowed in API responses.
     *
     * @param fields array of field names that are allowed in API responses
     */
    public void setApiResponseFields(final String[] fields) {
        apiResponseFieldSet = new HashSet<>();
        Collections.addAll(apiResponseFieldSet, fields);
    }

    /**
     * Checks if the specified field is allowed in API responses.
     *

def test_read_dict():
    response = client.get("/dict")
    assert response.status_code == 200, response.text
    assert response.json() == {"name": "Foo"}


def test_read_model():
    response = client.get("/model")
    assert response.status_code == 200, response.text
    assert response.json() == {"name": "Foo"}


def test_read_list():
    response = client.get("/list")

# Custom Response - HTML, Stream, File, others { #custom-response-html-stream-file-others }

By default, **FastAPI** will return JSON responses.

You can override it by returning a `Response` directly as seen in [Return a Response directly](response-directly.md).

### Add some custom `tags`, `responses`, and `dependencies` { #add-some-custom-tags-responses-and-dependencies }

We are not adding the prefix `/items` nor the `tags=["items"]` to each *path operation* because we added them to the `APIRouter`.

But we can still add _more_ `tags` that will be applied to a specific *path operation*, and also some extra `responses` specific to that *path operation*:
