    * Dann gibt es die von der entsprechenden *Pfadoperation* generierte `response` zurück.

/// tip | Tipp

Sie müssen `WSGIMiddleware` importieren.

Wrappen Sie dann die WSGI-Anwendung (z. B. Flask) mit der Middleware.

Und dann mounten Sie das auf einem Pfad.

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

## Es testen { #check-it }

Jetzt wird jeder <abbr title="Request – Anfrage: Daten, die der Client zum Server sendet">Request</abbr> unter dem Pfad `/v1/` von der Flask-Anwendung verarbeitet.

        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.).
