## Exemple plus poussé

Maintenant, modifiez le fichier `main.py` pour recevoir <abbr title="en anglais : body">le corps</abbr> d'une requête `PUT`.

Déclarez ce corps en utilisant les types Python standards, grâce à Pydantic.

```Python hl_lines="4  9-12  25-27"

  }

  @Override
  final ImmutableSet<V> createValues() {
    throw new AssertionError("should never be called");
  }

  /**
   * Guaranteed to throw an exception and leave the bimap unmodified.
   *
   * @throws UnsupportedOperationException always
   * @deprecated Unsupported operation.
   */
  @CanIgnoreReturnValue
  @Deprecated
  @Override

```Python hl_lines="14-17" title="app/main.py"
{!../../docs_src/bigger_applications/app/main.py!}
```

That way, the original `APIRouter` will stay unmodified, so we can still share that same `app/internal/admin.py` file with other projects in the organization.

The result is that in our app, each of the *path operations* from the `admin` module will have:

* The prefix `/admin`.

- Kube-apiserver: resolved a regression that treated `304 Not Modified` responses from aggregated API servers as internal errors ([#112530](https://github.com/kubernetes/kubernetes/pull/112530), [@liggitt](https://github.com/liggitt)) [SIG API Machinery]

Para este exemplo, será super simples. Mas digamos que, como ele é compartilhado com outros projetos na organização, não podemos modificá-lo e adicionar um `prefix`, `dependencies`, `tags`, etc. diretamente ao `APIRouter`:

```Python hl_lines="3" title="app/internal/admin.py"
{!../../docs_src/bigger_applications/app/internal/admin.py!}
```

e.offsets=r({},e.offsets,t._config.offset(e.offsets,t._element)),e}:e.offset=this._config.offset,e},e._getPopperConfig=function(){var t={placement:this._getPlacement(),modifiers:{offset:this._getOffset(),flip:{enabled:this._config.flip},preventOverflow:{boundariesElement:this._config.boundary}}};return"static"===this._config.display&&(t.modifiers.applyStyle={enabled:!1}),r({},t,this._config.popperConfig)},t._jQueryInterface=function(e){return this.each((function(){var n=o.default(this).data(K);if(n||(n=new...

## Token JWT con scopes

Ahora, modifica la *path operation* del token para devolver los scopes solicitados.

Todavía estamos usando el mismo `OAuth2PasswordRequestForm`. Incluye una propiedad `scopes` con una `list` de `str`, con cada scope que recibió en el request.

## Actualización del Ejemplo

Ahora modifica el archivo `main.py` para recibir un body desde un request `PUT`.

Declara el body usando tipos estándar de Python, gracias a Pydantic.
