    * Затем она возвращает ответ `response`, сгенерированный *операцией пути*.
* Также имеется возможность видоизменить `response`, перед тем как его вернуть.

/// tip | Примечание

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**.

## Using `WSGIMiddleware` { #using-wsgimiddleware }

You need to import `WSGIMiddleware`.

Then wrap the WSGI (e.g. Flask) app with the middleware.

And then mount that under a path.

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

## Check it { #check-it }

Now, every request under the path `/v1/` will be handled by the Flask application.

And the rest will be handled by **FastAPI**.

{* ../../docs_src/dependencies/tutorial007_py39.py hl[2:4] *}

Der ge`yield`ete Wert ist das, was in *Pfadoperationen* und andere Abhängigkeiten eingefügt wird:

{* ../../docs_src/dependencies/tutorial007_py39.py hl[4] *}

Der auf die `yield`-Anweisung folgende Code wird nach der Response ausgeführt:

{* ../../docs_src/dependencies/tutorial007_py39.py hl[5:6] *}
