`Query`, `Path` ve `Cookie` parametrelerini nasıl tanımlıyorsanız, Header parametrelerini de aynı şekilde tanımlayabilirsiniz.

## `Header`'ı Import Edin { #import-header }

Önce `Header`'ı import edin:

## `Header` Parametrelerini Tanımlayın { #declare-header-parameters }

## Request body + parámetros de path { #request-body-path-parameters }

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**.
