# 使用yield的依赖项

FastAPI支持在完成后执行一些<abbr title='有时也被称为“退出”("exit")，“清理”("cleanup")，“拆卸”("teardown")，“关闭”("close")，“上下文管理器”("context managers")。 ...'>额外步骤</abbr>的依赖项.

为此，请使用 `yield` 而不是 `return`，然后再编写额外的步骤（代码）。

!!! tip "提示"
    确保只使用一次 `yield` 。

!!! note "技术细节"

    任何一个可以与以下内容一起使用的函数：

# Python Veri Tiplerine Giriş

Python isteğe bağlı olarak "tip belirteçlerini" destekler.

 **"Tip belirteçleri"** bir değişkenin <abbr title="örneğin: str, int, float, bool">tipinin</abbr> belirtilmesine olanak sağlayan özel bir sözdizimidir.

Değişkenlerin tiplerini belirterek editör ve araçlardan daha fazla destek alabilirsiniz.

This part is pretty normal, most of the code is probably already familiar to you:

```Python hl_lines="9-13  36-53"
{!../../../docs_src/openapi_callbacks/tutorial001.py!}
```

!!! tip
    The `callback_url` query parameter uses a Pydantic <a href="https://docs.pydantic.dev/latest/concepts/types/#urls" class="external-link" target="_blank">URL</a> type.
