## Mehrere Body-Parameter { #multiple-body-parameters }

Im vorherigen Beispiel erwarteten die *Pfadoperationen* einen JSON-Body mit den Attributen eines `Item`s, etwa:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

{* ../../docs_src/openapi_callbacks/tutorial001_py310.py hl[33] *}

/// tip | Tipp

Beachten Sie, dass Sie nicht den Router selbst (`invoices_callback_router`) an `callback=` übergeben, sondern das Attribut `.routes`, wie in `invoices_callback_router.routes`.

///

* `tags: List[str] = []` tem um padrão de uma lista vazia: `[]`.

mas você pode querer omiti-los do resultado se eles não foram realmente armazenados.

Por exemplo, se você tem modelos com muitos atributos opcionais em um banco de dados NoSQL, mas não quer enviar respostas JSON muito longas cheias de valores padrão.

### Use o parâmetro `response_model_exclude_unset` { #use-the-response-model-exclude-unset-parameter }
