## Documentar la Deprecación de una *Path Operation* - OpenAPI

Para deprecar una *path operation*, y mostrarla en la interfaz de usuario de la documentación, lee la documentación para [Tutorial - Configuraciones de Path Operation - Deprecación](../tutorial/path-operation-configuration.md#deprecate-a-path-operation){.internal-link target=_blank}.

## Convertir cualquier Dato a Compatible con JSON

            return null;
        }
        final String path = LaServletContextUtil.getServletContext().getRealPath(osddPath);
        if (path == null) {
            logger.warn("{} was not found.", path);
            return null;
        }
        final File osddFile = new File(path);
        if (!osddFile.isFile()) {
            logger.warn("{} was not a file.", path);
            return null;
        }
        return osddFile;

Similar a como puedes [agregar `dependencies` a los *path operation decorators*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank}, puedes agregarlos a la aplicación de `FastAPI`.

En ese caso, se aplicarán a todas las *path operations* en la aplicación:

## `PATH` Environment Variable { #path-environment-variable }

There is a **special** environment variable called **`PATH`** that is used by the operating systems (Linux, macOS, Windows) to find programs to run.

## Request body + parámetros de path

Puedes declarar parámetros de path y request body al mismo tiempo.

**FastAPI** reconocerá que los parámetros de función que coinciden con los parámetros de path deben ser **tomados del path**, y que los parámetros de función que se declaran como modelos de Pydantic deben ser **tomados del request body**.
