# Abhängigkeiten mit yield

FastAPI unterstützt Abhängigkeiten, die nach Abschluss einige <abbr title="Manchmal auch genannt „Exit Code“, „Cleanup Code“, „Teardown Code“, „Closing Code“, „Kontext Manager Exit Code“, usw.">zusätzliche Schritte ausführen</abbr>.

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

/// tip | Tipp

Stellen Sie sicher, dass Sie `yield` nur einmal pro Abhängigkeit verwenden.

   **FastAPI** использует их "под капотом" с этой целью.

## Зависимости с `yield` и `HTTPException`

Вы видели, что можно использовать зависимости с `yield` совместно с блоком `try`, отлавливающие исключения.

Таким же образом вы можете поднять исключение `HTTPException` или что-то подобное в завершающем коде, после `yield`.
