# Зависимости с yield

FastAPI поддерживает зависимости, которые выполняют некоторые <abbr title='также известные как "exit", "cleanup", "teardown", "close", "context managers", ...'>дополнительные действия после завершения работы</abbr>.

Для этого используйте `yield` вместо `return`, а дополнительный код напишите после него.

/// tip | Подсказка

Обязательно используйте `yield` один-единственный раз.

Uma vantagem particular que nem sempre é óbvia é que você pode **gerar clientes** (às vezes chamados de <abbr title="Software Development Kits">**SDKs**</abbr>) para a sua API, para muitas **linguagens de programação** diferentes.

## Geradores de Clientes OpenAPI

Existem muitas ferramentas para gerar clientes a partir do **OpenAPI**.

# yieldを持つ依存関係

FastAPIは、いくつかの<abbr title='時々"exit"、"cleanup"、"teardown"、"close"、"context managers"、 ...のように呼ばれる'>終了後の追加のステップ</abbr>を行う依存関係をサポートしています。

これを行うには、`return`の代わりに`yield`を使い、その後に追加のステップを書きます。

/// tip | 豆知識

`yield`は必ず一度だけ使用するようにしてください。

/// info | 情報

これを動作させるには、**Python 3.7** 以上を使用するか、**Python 3.6** では"backports"をインストールする必要があります:

```
pip install async-exit-stack async-generator
```
