## 同じ依存関係の複数回の使用

依存関係の１つが同じ*path operation*に対して複数回宣言されている場合、例えば、複数の依存関係が共通のサブ依存関係を持っている場合、**FastAPI** はリクエストごとに１回だけそのサブ依存関係を呼び出します。

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

Sie können mehr als eine Eventhandler-Funktion hinzufügen.

Und Ihre Anwendung empfängt erst dann Anfragen, wenn alle `startup`-Eventhandler abgeschlossen sind.

## 체크하기

여러분의 도커 컨테이너 URL에서 실행 사항을 체크할 수 있습니다. 예를 들어: <a href="http://192.168.99.100/items/5?q=somequery" class="external-link" target="_blank">http://192.168.99.100/items/5?q=somequery</a> 또는 <a href="http://127.0.0.1/items/5?q=somequery" class="external-link" target="_blank">http://127.0.0.1/items/5?q=somequery</a> (또는 동일하게, 여러분의 도커 호스트를 이용해서 체크할 수도 있습니다).

아래와 비슷한 것을 보게 될 것입니다:
