Diese Funktionen können mit `async def` oder normalem `def` deklariert werden.

### `startup`-Event

Um eine Funktion hinzuzufügen, die vor dem Start der Anwendung ausgeführt werden soll, deklarieren Sie diese mit dem Event `startup`:

{* ../../docs_src/events/tutorial001.py hl[8] *}

In diesem Fall initialisiert die Eventhandler-Funktion `startup` die „Datenbank“ der Items (nur ein `dict`) mit einigen Werten.

# Status Codes

You can import the `status` module from `fastapi`:

```python
from fastapi import status
```

`status` is provided directly by Starlette.

It contains a group of named constants (variables) with integer status codes.

For example:

* 200: `status.HTTP_200_OK`
* 403: `status.HTTP_403_FORBIDDEN`
* etc.

        }
      };

  /** Constructor for use by subclasses. */
  protected AbstractExecutionThreadService() {}

  /**
   * Start the service. This method is invoked on the execution thread.
   *
   * <p>By default this method does nothing.
   */
  protected void startUp() throws Exception {}

  /**
   * Run the service. This method is invoked on the execution thread. Implementations must respond

# Response - Изменение cтатус кода

Вы, вероятно, уже читали о том, что можно установить [Состояние ответа по умолчанию](../tutorial/response-status-code.md){.internal-link target=_blank}.

Но в некоторых случаях вам нужно вернуть код состояния, отличный от установленного по умолчанию.

## Пример использования

Например, представьте, что вы хотите возвращать HTTP код состояния "OK" `200` по умолчанию.

# Response – Statuscode ändern

Sie haben wahrscheinlich schon vorher gelesen, dass Sie einen Standard-[Response-Statuscode](../tutorial/response-status-code.md){.internal-link target=_blank} festlegen können.

In manchen Fällen müssen Sie jedoch einen anderen als den Standard-Statuscode zurückgeben.

## Anwendungsfall

Stellen Sie sich zum Beispiel vor, Sie möchten standardmäßig den HTTP-Statuscode „OK“ `200` zurückgeben.
