# Зависимости с yield { #dependencies-with-yield }

FastAPI поддерживает зависимости, которые выполняют некоторые <abbr title='иногда также называемые "exit code", "cleanup code", "teardown code", "closing code", "context manager exit code" и т.п.'>дополнительные шаги после завершения</abbr>.

Для этого используйте `yield` вместо `return`, а дополнительные шаги (код) напишите после него.

/// tip | Подсказка

FastAPI unterstützt Abhängigkeiten, die nach Abschluss einige <abbr title="Manchmal auch genannt „Exit Code“, „Cleanup Code“, „Teardown Code“, „Closing Code“, „Kontextmanager 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

如果你使用的FastAPI的版本早于0.106.0，并且在使用后台任务中使用了包含 `yield` 的依赖项中的资源，那么这些细节会对你有一些用处。

///

### 包含 `yield` 和 `except` 的依赖项的技术细节

在FastAPI 0.110.0版本之前，如果使用了一个包含 `yield` 的依赖项，你在依赖项中使用 `except` 捕获了一个异常，但是你没有再次抛出该异常，这个异常会被自动抛出/转发到异常处理器或者内部服务错误处理器。

### 后台任务和使用 `yield` 的依赖项的技术细节

在FastAPI 0.106.0版本之前，在 `yield` 后面抛出异常是不可行的，因为 `yield` 之后的退出代码是在响应被发送之后再执行，这个时候异常处理器已经执行过了。

这样设计的目的主要是为了允许在后台任务中使用被依赖项`yield`的对象，因为退出代码会在后台任务结束后再执行。

## `yield`と`HTTPException`を持つ依存関係

`yield`と例外をキャッチする`try`ブロックを持つことができる依存関係を使用することができることがわかりました。

`yield`の後の終了コードで`HTTPException`などを発生させたくなるかもしれません。しかし**それはうまくいきません**

`yield`を持つ依存関係の終了コードは[例外ハンドラ](../handling-errors.md#_4){.internal-link target=_blank}の*後に*実行されます。依存関係によって投げられた例外を終了コード（`yield`の後）でキャッチするものはなにもありません。
