## Resumen

Ahora puedes obtener el usuario actual directamente en tu *path operation function*.

Ya estamos a mitad de camino.

Solo necesitamos agregar una *path operation* para que el usuario/cliente envíe realmente el `username` y `password`.

Por ejemplo, cuando usas GraphQL normalmente realizas todas las acciones usando solo operaciones `POST`.

### Paso 4: define la **path operation function**

Esta es nuestra "**path operation function**":

* **path**: es `/`.
* **operation**: es `get`.
* **function**: es la función debajo del "decorador" (debajo de `@app.get("/")`).

{* ../../docs_src/first_steps/tutorial001.py hl[7] *}

But you can also declare the `Response` that you want to be used (e.g. any `Response` subclass), in the *path operation decorator* using the `response_class` parameter.

The contents that you return from your *path operation function* will be put inside of that `Response`.

/// tip

Note that, much like [dependencies in *path operation decorators*](dependencies/dependencies-in-path-operation-decorators.md){.internal-link target=_blank}, no value will be passed to your *path operation function*.

///

The end result is that the item paths are now:

* `/items/`
* `/items/{item_id}`

...as we intended.
