Si ocurre una excepción, la `Request instance` aún estará en el alcance, así que podemos leer y hacer uso del request body cuando manejamos el error:

{* ../../docs_src/custom_request_and_route/tutorial002.py hl[16:18] *}

## Clase personalizada `APIRoute` en un router

También puedes establecer el parámetro `route_class` de un `APIRouter`:

{* ../../docs_src/custom_request_and_route/tutorial003.py hl[26] *}

If an exception occurs, the`Request` instance will still be in scope, so we can read and make use of the request body when handling the error:

{* ../../docs_src/custom_request_and_route/tutorial002.py hl[16:18] *}

## Custom `APIRoute` class in a router { #custom-apiroute-class-in-a-router }

You can also set the `route_class` parameter of an `APIRouter`:

{* ../../docs_src/custom_request_and_route/tutorial003.py hl[26] *}
