(`BackgroundTask`가 아닌) `BackgroundTasks`를 사용하면, _경로 작동 함수_ 매개변수로 사용할 수 있게 되고 나머지는 **FastAPI**가 대신 처리하도록 할 수 있습니다. 이것은 `Request` 객체를 직접 사용하는 것과 같은 방식입니다.

FastAPI에서 `BackgroundTask`를 단독으로 사용하는 것은 여전히 가능합니다. 하지만 객체를 코드에서 생성하고, 이 객체를 포함하는 Starlette `Response`를 반환해야 합니다.

上面的应用程序是一个最小和简单的示例，用于演示如何处理和向多个 WebSocket 连接广播消息。

但请记住，由于所有内容都在内存中以单个列表的形式处理，因此它只能在进程运行时工作，并且只能使用单个进程。

如果您需要与 FastAPI 集成更简单但更强大的功能，支持 Redis、PostgreSQL 或其他功能，请查看 [encode/broadcaster](https://github.com/encode/broadcaster)。

/// tip | Consejo

Para declarar un parámetro de query con un tipo de `list`, como en el ejemplo anterior, necesitas usar explícitamente `Query`, de lo contrario sería interpretado como un request body.
