## Вызов `uvicorn` { #call-uvicorn }

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

{* ../../docs_src/debugging/tutorial001_py39.py hl[1,15] *}

### Описание `__name__ == "__main__"` { #about-name-main }

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

<div class="termy">

Imaginemos que quieres obtener la dirección IP/host del cliente dentro de tu *path operation function*.

Para eso necesitas acceder al request directamente.

{* ../../docs_src/using_request_directly/tutorial001_py39.py hl[1,7:8] *}

Al declarar un parámetro de *path operation function* con el tipo siendo `Request`, **FastAPI** sabrá pasar el `Request` en ese parámetro.

/// tip | Consejo

Puedes usar fácilmente las mismas configuraciones de Pydantic para configurar tu OpenAPI generado y las interfaces de usuario de la documentación.

Por ejemplo:

{* ../../docs_src/conditional_openapi/tutorial001_py39.py hl[6,11] *}

Aquí declaramos la configuración `openapi_url` con el mismo valor por defecto de `"/openapi.json"`.

Y luego la usamos al crear la app de `FastAPI`.
