Daher deklarieren wir die Eventhandler-Funktion mit Standard-`def` statt mit `async def`.

///

### `startup` und `shutdown` zusammen { #startup-and-shutdown-together }

Es besteht eine hohe Wahrscheinlichkeit, dass die Logik für Ihr *Startup* und *Shutdown* miteinander verknüpft ist. Vielleicht möchten Sie etwas beginnen und es dann beenden, eine Ressource laden und sie dann freigeben usw.

///

Переменная `oauth2_scheme` — это экземпляр `OAuth2PasswordBearer`, но она также «вызываемая».

Ее можно вызвать так:

```Python
oauth2_scheme(some, parameters)
```

Поэтому ее можно использовать вместе с `Depends`.

### Использование { #use-it }

Теперь вы можете передать `oauth2_scheme` как зависимость с `Depends`.

И всё.

**2 строки.**

И она имеет ту же форму и структуру, что и все ваши *функции обработки пути*.

Можно думать о ней как о *функции обработки пути* без «декоратора» (без `@app.get("/some-path")`).

И она может возвращать что угодно.

В этом случае эта зависимость ожидает:

* Необязательный query-параметр `q` типа `str`.
* Необязательный query-параметр `skip` типа `int`, по умолчанию `0`.
