### A expressão do path do callback { #the-callback-path-expression }

O *path* do callback pode ter uma <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#key-expression" class="external-link" target="_blank">expressão OpenAPI 3</a> que pode conter partes da solicitação original enviada para *sua API*.

/// note | Detalles Técnicos de Starlette

El `UploadFile` de **FastAPI** hereda directamente del `UploadFile` de **Starlette**, pero añade algunas partes necesarias para hacerlo compatible con **Pydantic** y las otras partes de FastAPI.

///

## Qué es "Form Data" { #what-is-form-data }

## Tamaño del código { #code-size }

Este ejemplo podría parecer extenso. Ten en cuenta que estamos mezclando seguridad, modelos de datos, funciones de utilidad y *path operations* en el mismo archivo.

Pero aquí está el punto clave.

{* ../../docs_src/path_operation_advanced_configuration/tutorial003_py39.py hl[6] *}

## Descrição avançada a partir de docstring { #advanced-description-from-docstring }

Você pode limitar as linhas utilizadas a partir de uma docstring de uma *função de operação de rota* para o OpenAPI.
