Necesitas importar `WSGIMiddleware`.

Luego envuelve la aplicación WSGI (p. ej., Flask) con el middleware.

Y luego móntala bajo un path.

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

## Revisa { #check-it }

Ahora, cada request bajo el path `/v1/` será manejado por la aplicación Flask.

Y el resto será manejado por **FastAPI**.

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.
