Команда `uvicorn main:app` обращается к:

* `main`: файл `main.py` (модуль Python).
* `app`: объект, созданный внутри файла `main.py` в строке `app = FastAPI()`.

이 경우 FastAPI는 리스트의 내용을 검사하지 않음을 명심하기 바랍니다.

예를 들어, `List[int]`는 리스트 내용이 정수인지 검사(및 문서화)합니다. 하지만 `list` 단독일 경우는 아닙니다.

# 测试 WebSockets

测试 WebSockets 也使用 `TestClient`。

为此，要在 `with` 语句中使用 `TestClient` 连接 WebSocket。
