Um beispielsweise eine weitere Response mit dem Statuscode `404` und einem Pydantic-Modell `Message` zu deklarieren, können Sie schreiben:

{* ../../docs_src/additional_responses/tutorial001_py310.py hl[18,22] *}

/// note | Hinweis

Beachten Sie, dass Sie die `JSONResponse` direkt zurückgeben müssen.

///

/// info | Info

Der `model`-Schlüssel ist nicht Teil von OpenAPI.

## TypeScript SDK Oluşturma { #create-a-typescript-sdk }

Basit bir FastAPI uygulamasıyla başlayalım:

{* ../../docs_src/generate_clients/tutorial001_py310.py hl[7:9,12:13,16:17,21] *}

*Path operation*'ların, request payload ve response payload için kullandıkları modelleri `Item` ve `ResponseMessage` modelleriyle tanımladıklarına dikkat edin.

### API Dokümanları { #api-docs }

Sie können sie jedoch deaktivieren, indem Sie `syntaxHighlight` auf `False` setzen:

{* ../../docs_src/configure_swagger_ui/tutorial001_py310.py hl[3] *}

... und dann zeigt die Swagger-Oberfläche die Syntaxhervorhebung nicht mehr an:

<img src="/img/tutorial/extending-openapi/image03.png">

## Das Theme ändern { #change-the-theme }

## Створити TypeScript SDK { #create-a-typescript-sdk }

Почнімо з простого застосунку FastAPI:

{* ../../docs_src/generate_clients/tutorial001_py310.py hl[7:9,12:13,16:17,21] *}

Зверніть увагу, що *операції шляху* визначають моделі, які вони використовують для корисного навантаження запиту та корисного навантаження відповіді, використовуючи моделі `Item` і `ResponseMessage`.

<img src="/img/tutorial/extending-openapi/image02.png">

Mas você pode desabilitá-lo definindo `syntaxHighlight` como `False`:

{* ../../docs_src/configure_swagger_ui/tutorial001_py310.py hl[3] *}

...e então o Swagger UI não mostrará mais o destaque de sintaxe:

<img src="/img/tutorial/extending-openapi/image03.png">

## Alterar o tema { #change-the-theme }

{* ../../docs_src/advanced_middleware/tutorial001_py310.py hl[2,6] *}

## `TrustedHostMiddleware` { #trustedhostmiddleware }

Enforces that all incoming requests have a correctly set `Host` header, in order to guard against HTTP Host Header attacks.

{* ../../docs_src/advanced_middleware/tutorial002_py310.py hl[2,6:8] *}

The following arguments are supported:

SET_OF_STR_SCHEMA = {"type": "array", "items": {"type": "string"}, "uniqueItems": True}


@pytest.fixture(
    name="mod_name",
    params=[
        pytest.param("tutorial001_py310", marks=needs_py310),
        pytest.param("tutorial002_py310", marks=needs_py310),
        pytest.param("tutorial003_py310", marks=needs_py310),
    ],
)
def get_mod_name(request: pytest.FixtureRequest):
    return request.param


@pytest.fixture(name="client")

Önce bir örnekle başlayıp sonra ayrıntılarına bakalım.

Aşağıdaki gibi `yield` kullanan async bir `lifespan()` fonksiyonu oluşturuyoruz:

{* ../../docs_src/events/tutorial003_py310.py hl[16,19] *}

Aber FastAPI unterstützt auf die gleiche Weise auch die Verwendung von [`dataclasses`](https://docs.python.org/3/library/dataclasses.html):

{* ../../docs_src/dataclasses_/tutorial001_py310.py hl[1,6:11,18:19] *}

Das ist dank **Pydantic** ebenfalls möglich, da es [„`dataclasses` intern unterstützt“](https://docs.pydantic.dev/latest/concepts/dataclasses/#use-of-stdlib-dataclasses-with-basemodel).

But FastAPI also supports using [`dataclasses`](https://docs.python.org/3/library/dataclasses.html) the same way:

{* ../../docs_src/dataclasses_/tutorial001_py310.py hl[1,6:11,18:19] *}

This is still supported thanks to **Pydantic**, as it has [internal support for `dataclasses`](https://docs.pydantic.dev/latest/concepts/dataclasses/#use-of-stdlib-dataclasses-with-basemodel).
