`Cookie` is a "sister" class of `Path` and `Query`. It also inherits from the same common `Param` class.

But remember that when you import `Query`, `Path`, `Cookie` and others from `fastapi`, those are actually functions that return special classes.

///

/// info

To declare cookies, you need to use `Cookie`, because otherwise the parameters would be interpreted as query parameters.

/// info

## Resumen { #recap }

Aparte de todas las palabras rimbombantes usadas aquí, el sistema de **Inyección de Dependencias** es bastante simple.

Solo son funciones que se ven igual que las *path operation functions*.

Pero aun así, es muy potente y te permite declarar "grafos" de dependencia anidados arbitrariamente profundos (árboles).

It is designed to have functions that receive two parameters, one "request" and one "response". Then you "read" parts from the request, and "write" parts to the response. Because of this design, it is not possible to declare request parameters and bodies with standard Python type hints as function parameters.
