Você precisa importar o `WSGIMiddleware`.

Em seguida, encapsule a aplicação WSGI (e.g. Flask) com o middleware.

E então monte isso sob um path.

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

## Confira { #check-it }

Agora, todas as requisições sob o path `/v1/` serão manipuladas pela aplicação Flask.

E o resto será manipulado pelo **FastAPI**.

from fastapi.testclient import TestClient

from docs_src.path_params.tutorial002_py39 import app

client = TestClient(app)


def test_get_items():
    response = client.get("/items/1")
    assert response.status_code == 200, response.text
    assert response.json() == {"item_id": 1}


def test_get_items_invalid_id():
    response = client.get("/items/item1")
    assert response.status_code == 422, response.text

Veamos de nuevo el ejemplo anterior:

{* ../../docs_src/response_status_code/tutorial001_py39.py hl[6] *}

`201` es el código de estado para "Created".

Pero no tienes que memorizar lo que significa cada uno de estos códigos.

Puedes usar las variables de conveniencia de `fastapi.status`.

{* ../../docs_src/response_status_code/tutorial002_py39.py hl[1,6] *}

    * Dann gibt es die von der entsprechenden *Pfadoperation* generierte `response` zurück.
* Sie können die `response` dann weiter modifizieren, bevor Sie sie zurückgeben.

{* ../../docs_src/middleware/tutorial001_py39.py hl[8:9,11,14] *}

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.
