!!! note "Detalles Técnicos"
    `Cookie` es una clase "hermana" de `Path` y `Query`. También hereda de la misma clase común `Param`.

    Pero recuerda que cuando importas `Query`, `Path`, `Cookie`  y otros de `fastapi`, en realidad son funciones que devuelven clases especiales.

!!! info
    Para declarar cookies, necesitas usar `Cookie`, porque de lo contrario los parámetros serían interpretados como parámetros de query.

## Resumen

    ```Python hl_lines="9"
    {!> ../../../docs_src/cookie_params/tutorial001.py!}
    ```

!!! note "Teknik Detaylar"
    `Cookie` sınıfı `Path` ve `Query` sınıflarının kardeşidir. Diğerleri gibi `Param` sınıfını miras alan bir sınıftır.

    Ancak `fastapi`'dan projenize dahil ettiğiniz `Query`, `Path`, `Cookie` ve diğerleri aslında özel sınıflar döndüren birer fonksiyondur.

		if params == c.Params() {
			return c, true
		}
	}
	return nil, false

* `le`: меньше или равно (`l`ess than or `e`qual)

!!! info "Информация"
    `Query`, `Path` и другие классы, которые мы разберём позже, являются наследниками общего класса `Param`.

    Все они используют те же параметры для дополнительной валидации и метаданных, которые вы видели ранее.
