/// note | 技术细节

任何一个可以与以下内容一起使用的函数：

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

都可以作为 **FastAPI** 的依赖项。

实际上，FastAPI内部就使用了这两个装饰器。

///

Aqui veremos um exemplo usando <a href="https://sqlmodel.tiangolo.com/" class="external-link" target="_blank">SQLModel</a>.

Starlette (e **FastAPI**) são baseados no <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>, o que o torna compatível com ambos o <a href="https://docs.python.org/3/library/asyncio-task.html" class="external-link" target="_blank">asyncio</a> da biblioteca padrão do Python, e o <a href="https://trio.readthedocs.io/en/stable/" class="external-link" target="_blank">Trio</a>.

Um das zu tun, verwenden Sie den Standard-Python-Typhinweis <a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>:

/// note | Hinweis

Для этого используйте стандартную аннотацию типов в Python <a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>:

사용하고자 하는 `Response` 클래스(하위 클래스)를 임포트한 후, **경로 작업 데코레이터*에서 선언하세요.

대규모 응답의 경우, 딕셔너리를 반환하는 것보다 `Response`를 반환하는 것이 훨씬 빠릅니다.
