在这种情况下，`myapp.py` 内部的自动变量不会有值为 `"__main__"` 的变量 `__name__`。

所以，下面这一行不会被执行：

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

## 使用你的调试器运行代码

由于是从代码直接运行的 Uvicorn 服务器，所以你可以从调试器直接调用 Python 程序（你的 FastAPI 应用）。

例如，你可以在 Visual Studio Code 中：

* 进入到「调试」面板。

Então, a linha:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

não será executada.

이 예시는 Pydantic 모델을 `dict`로, `datetime` 형식을 `str`로 변환합니다.

이렇게 호출한 결과는 파이썬 표준인 <a href="https://docs.python.org/3/library/json.html#json.dumps" class="external-link" target="_blank">`json.dumps()`</a>로 인코딩 할 수 있습니다.

길이가 긴 문자열 형태의 JSON 형식(문자열)의 데이터가 들어있는 상황에서는 `str`로 반환하지 않습니다. JSON과 모두 호환되는 값과 하위 값이 있는 Python 표준 데이터 구조 (예: `dict`)를 반환합니다.
