!!! note "技術詳細"
    以下と一緒に使用できる関数なら何でも有効です:

    * <a href="https://docs.python.org/3/library/contextlib.html#contextlib.contextmanager" class="external-link" target="_blank">`@contextlib.contextmanager`</a>または

В Python для создания менеджеров контекста можно <a href="https://docs.python.org/3/reference/datamodel.html#context-managers" class="external-link" target="_blank">создать класс с двумя методами: `__enter__()` и `__exit__()`</a>.

Вы также можете использовать их внутри зависимостей **FastAPI** с `yield`, используя операторы
`with` или `async with` внутри функции зависимости:

```Python hl_lines="1-9  13"

!!! warning
    这是一个更为“高级”的想法。

    如果您刚开始使用**FastAPI**，您可能暂时可以跳过它。

在Python中，你可以通过<a href="https://docs.python.org/3/reference/datamodel.html#context-managers" class="external-link" target="_blank">创建一个带有`__enter__()`和`__exit__()`方法的类</a>来创建上下文管理器。

你也可以在**FastAPI**的依赖项中使用带有`yield`的`with`或`async with`语句，通过在依赖函数内部使用它们。

```Python hl_lines="1-9  13"
{!../../../docs_src/dependencies/tutorial010.py!}
```
