<span style="color: green;">INFO</span>:     Application startup complete.
```

</div>

!!! note "참고"
    `uvicorn main:app` 명령은 다음을 의미합니다:

    * `main`: 파일 `main.py` (파이썬 "모듈").
    * `app`: `main.py` 내부의 `app = FastAPI()` 줄에서 생성한 오브젝트.
    * `--reload`: 코드 변경 시 자동으로 서버 재시작. 개발 시에만 사용.

출력되는 줄들 중에는 아래와 같은 내용이 있습니다:

```hl_lines="4"

<span style="color: green;">INFO</span>:     Application startup complete.
```

</div>

!!! note "備考"
    `uvicorn main:app`は以下を示します:

    * `main`: `main.py`ファイル (Python "module")。
    * `app`:  `main.py`内部で作られるobject（`app = FastAPI()`のように記述される）。
    * `--reload`: コードの変更時にサーバーを再起動させる。開発用。

出力には次のような行があります:

```hl_lines="4"

# (1)
COPY ./main.py /code/

# (2)
CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "80"]
```

1. Copie o arquivo `main.py` para o diretório `/code` diretamente (sem nenhum diretório `./app`).

2. Execute o Uvicorn e diga a ele para importar o objeto `app` de `main` (em vez de importar de `app.main`).

В вашем FastAPI приложении, импортируйте и вызовите `uvicorn` напрямую:

```Python hl_lines="1  15"
{!../../../docs_src/debugging/tutorial001.py!}
```

### Описание `__name__ == "__main__"`

Главная цель использования `__name__ == "__main__"` в том, чтобы код выполнялся при запуске файла с помощью:

<div class="termy">

```console
$ python myapp.py
```

</div>

```Python hl_lines="1  3  7" title="app/main.py"
{!../../../docs_src/bigger_applications/app/main.py!}
```

### 🗄 `APIRouter`

🔜 👥 🗄 🎏 🔁 👈 ✔️ `APIRouter`Ⓜ:

```Python hl_lines="5" title="app/main.py"
{!../../../docs_src/bigger_applications/app/main.py!}
```

    /**
     * Resolves the main artifact of the specified plugin.
     *
     * @param plugin The plugin for which to resolve the main artifact, must not be {@code null}.
     * @param repositories The plugin repositories to use for resolving the plugin's main artifact, must not be {@code
     *            null}.
     * @param session The repository session to use for resolving the plugin's main artifact, must not be {@code null}.

```

### Check the automatic API docs

Now, run `uvicorn` with the main app, if your file is `main.py`, it would be:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

```

</div>

Let's see what each of those options mean:

* `main:app`: This is the same syntax used by Uvicorn, `main` means the Python module named "`main`", so, a file `main.py`. And `app` is the name of the variable that is the **FastAPI** application.
    * You can imagine that `main:app` is equivalent to a Python `import` statement like:

        ```Python
        from main import app
        ```

# (1)
COPY ./main.py /code/

# (2)
CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "80"]
```

1. Copy the `main.py` file to the `/code` directory directly (without any `./app` directory).

2. Run Uvicorn and tell it to import the `app` object from `main` (instead of importing from `app.main`).
