Eine Middleware muss nicht speziell für FastAPI oder Starlette gemacht sein, um zu funktionieren, solange sie der ASGI-Spezifikation genügt.

Im Allgemeinen handelt es sich bei ASGI-Middleware um Klassen, die als erstes Argument eine ASGI-Anwendung erwarten.

In der Dokumentation für ASGI-Middlewares von Drittanbietern wird Ihnen wahrscheinlich gesagt, etwa Folgendes zu tun:

```Python
from unicorn import UnicornMiddleware

```

`.add_task()` reçoit comme arguments :

* Une fonction de tâche à exécuter en arrière-plan (`write_notification`).
* Les arguments positionnels à passer à la fonction de tâche dans l'ordre (`email`).
* Les arguments nommés à passer à la fonction de tâche (`message="some notification"`).

## Eine „aufrufbare“ Instanz

In Python gibt es eine Möglichkeit, eine Instanz einer Klasse „aufrufbar“ („callable“) zu machen.

Nicht die Klasse selbst (die bereits aufrufbar ist), sondern eine Instanz dieser Klasse.

Dazu deklarieren wir eine Methode `__call__`:

=== "Python 3.9+"

    ```Python hl_lines="12"
    {!> ../../../docs_src/dependencies/tutorial011_an_py39.py!}

!!! info "Informação"
    `Query`, `Path` e outras classes que você verá a frente são subclasses de uma classe comum `Param`.

    Todas elas compartilham os mesmos parâmetros para validação adicional e metadados que você viu.

!!! note "Detalhes Técnicos"
    Quando você importa `Query`, `Path` e outras de `fastapi`, elas são na verdade funções.

    Que quando chamadas, retornam instâncias de classes de mesmo nome.
