Нужно импортировать `WSGIMiddleware`.

Затем оберните WSGI‑приложение (например, Flask) в middleware (Промежуточный слой).

После этого смонтируйте его на путь.

{* ../../docs_src/wsgi/tutorial001_py39.py hl[2:3,3] *}

## Проверьте { #check-it }

Теперь каждый HTTP‑запрос по пути `/v1/` будет обрабатываться приложением Flask.

А всё остальное будет обрабатываться **FastAPI**.

from fastapi.testclient import TestClient

from docs_src.metadata.tutorial001_py39 import app

client = TestClient(app)


def test_items():
    response = client.get("/items/")
    assert response.status_code == 200, response.text
    assert response.json() == [{"name": "Katana"}]


def test_openapi_schema():
    response = client.get("/openapi.json")
    assert response.status_code == 200, response.text
    assert response.json() == {

import importlib

        pytest.param("tutorial001_an_py310", marks=needs_py310),
    ],

        pytest.param("tutorial001_py39"),

        pytest.param("tutorial001_an_py39"),

Чтобы отключить её, установите их URL в значение `None` при создании вашего приложения `FastAPI`:

{* ../../docs_src/custom_docs_ui/tutorial001_py39.py hl[8] *}

### Подключить пользовательскую документацию { #include-the-custom-docs }

Теперь вы можете создать *операции пути* для пользовательской документации.

@pytest.fixture(scope="module")
def client():
    static_dir: Path = Path(os.getcwd()) / "static"
    print(static_dir)
    static_dir.mkdir(exist_ok=True)
    from docs_src.custom_docs_ui.tutorial001_py39 import app

    with TestClient(app) as client:
        yield client
    static_dir.rmdir()


def test_swagger_ui_html(client: TestClient):
    response = client.get("/docs")

Y luego puedes establecer el `status_code` en ese objeto de response *temporal*.

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

Y luego puedes devolver cualquier objeto que necesites, como lo harías normalmente (un `dict`, un modelo de base de datos, etc.).
