# Abhängigkeiten mit `yield` { #dependencies-with-yield }

FastAPI unterstützt Abhängigkeiten, die einige <dfn title="manchmal auch genannt: „Exit Code“, „Cleanup Code“, „Teardown Code“, „Closing Code“, „Kontextmanager Exit Code“, usw.">zusätzliche Schritte nach Abschluss</dfn> ausführen.

Verwenden Sie dazu `yield` statt `return` und schreiben Sie die zusätzlichen Schritte / den zusätzlichen Code danach.

# `yield`를 사용하는 의존성 { #dependencies-with-yield }

FastAPI는 <dfn title='때로는 "exit code", "cleanup code", "teardown code", "closing code", "context manager exit code" 등으로도 불립니다'>작업 완료 후 추가 단계</dfn>를 수행하는 의존성을 지원합니다.

이를 구현하려면 `return` 대신 `yield`를 사용하고, 추가로 실행할 단계 (코드)를 그 뒤에 작성하세요.

/// tip

각 의존성마다 `yield`는 한 번만 사용해야 합니다.
