You can easily use the same Pydantic settings to configure your generated OpenAPI and the docs UIs.

For example:

{* ../../docs_src/conditional_openapi/tutorial001_py39.py hl[6,11] *}

Here we declare the setting `openapi_url` with the same default of `"/openapi.json"`.

And then we use it when creating the `FastAPI` app.

import importlib

import pytest
from fastapi.testclient import TestClient

from ...utils import needs_py310


@pytest.fixture(
    name="client",
    params=[
        "tutorial001_py39",
        pytest.param("tutorial001_py310", marks=needs_py310),
        "tutorial001_an_py39",
        pytest.param("tutorial001_an_py310", marks=needs_py310),
    ],
)
def get_client(request: pytest.FixtureRequest):

{* ../../docs_src/advanced_middleware/tutorial001_py39.py hl[2,6] *}

## `TrustedHostMiddleware` { #trustedhostmiddleware }

Erzwingt, dass alle eingehenden Requests einen korrekt gesetzten `Host`-Header haben, um sich vor HTTP-Host-Header-Angriffen zu schützen.

{* ../../docs_src/advanced_middleware/tutorial002_py39.py hl[2,6:8] *}

Die folgenden Argumente werden unterstützt:

Sie können diese wie folgt setzen:

{* ../../docs_src/metadata/tutorial001_py39.py hl[3:16, 19:32] *}

/// tip | Tipp

Sie können Markdown im Feld `description` verwenden, und es wird in der Ausgabe gerendert.

///

Puedes configurarlos de la siguiente manera:

{* ../../docs_src/metadata/tutorial001_py39.py hl[3:16, 19:32] *}

/// tip | Consejo

Puedes escribir Markdown en el campo `description` y se mostrará en el resultado.

///

Con esta configuración, la documentación automática de la API se vería así:

{* ../../docs_src/path_params/tutorial005_py39.py hl[17] *}

#### Получение *значения перечисления* { #get-the-enumeration-value }

Можно получить фактическое значение (в данном случае - `str`) с помощью `model_name.value` или в общем случае `your_enum_member.value`:

{* ../../docs_src/path_params/tutorial005_py39.py hl[20] *}

/// tip | Подсказка

## `uvicorn` aufrufen { #call-uvicorn }

Importieren und führen Sie `uvicorn` direkt in Ihrer FastAPI-Anwendung aus:

{* ../../docs_src/debugging/tutorial001_py39.py hl[1,15] *}

### Über `__name__ == "__main__"` { #about-name-main }

Der Hauptzweck von `__name__ == "__main__"` ist, dass Code ausgeführt wird, wenn Ihre Datei mit folgendem Befehl aufgerufen wird:

Vamos imaginar que você deseja obter o endereço de IP/host do cliente dentro da sua *função de operação de rota*.

Para isso você precisa acessar a requisição diretamente.

{* ../../docs_src/using_request_directly/tutorial001_py39.py hl[1,7:8] *}

Ao declarar o parâmetro com o tipo sendo um `Request` em sua *função de operação de rota*, o **FastAPI** saberá como passar o `Request` neste parâmetro.
