Haciendo esto, nuestro `GzipRequest` se encargará de descomprimir los datos (si es necesario) antes de pasarlos a nuestras *path operations*.

Después de eso, toda la lógica de procesamiento es la misma.

Pero debido a nuestros cambios en `GzipRequest.body`, el request body se descomprimirá automáticamente cuando sea cargado por **FastAPI** si es necesario.

### Étape 3: créer une *opération de chemin*

#### Chemin

Chemin, ou "path" fait référence ici à la dernière partie de l'URL démarrant au premier `/`.

Donc, dans un URL tel que :

```
https://example.com/items/foo
```

...le "path" serait :

```
/items/foo
```

/// info

Un chemin, ou "path" est aussi souvent appelé route ou "endpoint".

///

#### Opération

ECL0103=Type({0}) is an interface not a class.
ECL0104=Argument({0}) is not an array.
ECL0105=Rethrew {0} as a runtime exception.
ECL0106=IOException occurred, because {0}
ECL0107=InvalidKeyException occurred, because {0}
ECL0108=The path is null.
ECL0109=Could not create a parent directory of {0}
ECL0110=A parent directory of {0} is not a directory.
ECL0111={0} is not a file.
ECL0112=Could not store {0}
ECL0113=NoSuchPaddingException occurred, because {0}

# Return a Response Directly { #return-a-response-directly }

When you create a **FastAPI** *path operation* you can normally return any data from it: a `dict`, a `list`, a Pydantic model, a database model, etc.

By default, **FastAPI** would automatically convert that return value to JSON using the `jsonable_encoder` explained in [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank}.
