Diese werden zu ihren entsprechenden Werten konvertiert (in diesem Fall Strings), bevor sie zum Client übertragen werden:

{* ../../docs_src/path_params/tutorial005.py hl[18,21,23] *}

In Ihrem Client erhalten Sie eine JSON-Response, wie etwa:

```JSON
{
  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}

예를 들어, NoSQL 데이터베이스에 많은 선택적 속성이 있는 모델이 있지만, 기본값으로 가득 찬 매우 긴 JSON 응답을 보내고 싶지 않습니다.

### `response_model_exclude_unset` 매개변수 사용

*경로 작동 데코레이터* 매개변수를 `response_model_exclude_unset=True`로 설정 할 수 있습니다:

{* ../../docs_src/response_model/tutorial004.py hl[24] *}

이러한 기본값은 응답에 포함되지 않고 실제로 설정된 값만 포함됩니다.

따라서 해당 *경로 작동*에 ID가 `foo`인 항목(items)을 요청으로 보내면 (기본값을 제외한) 응답은 다음과 같습니다:

```JSON
{
    "name": "Foo",
    "price": 50.2
}

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Wenn Sie dann zu den URLs unter `/openapi.json`, `/docs` oder `/redoc` gehen, erhalten Sie lediglich einen `404 Not Found`-Fehler, wie:

```JSON
{
    "detail": "Not Found"
}

## Daten in etwas JSON-kompatibles konvertieren

Um Daten in etwas JSON-kompatibles zu konvertieren, lesen Sie die Dokumentation unter [Tutorial – JSON-kompatibler Encoder](../tutorial/encoder.md){.internal-link target=_blank}.

## OpenAPI-Metadaten – Dokumentation

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Luego, si vas a las URLs en `/openapi.json`, `/docs`, o `/redoc`, solo obtendrás un error `404 Not Found` como:

```JSON
{
    "detail": "Not Found"
}

Наприклад, ця модель вище оголошує JSON "`об'єкт`" (або Python `dict`), як:

```JSON
{
    "name": "Foo",
    "description": "An optional description",
    "price": 45.2,
    "tax": 3.5
}
```

...оскільки `description` і `tax` є необов'язковими (зі значенням за замовчуванням `None`), цей JSON "`об'єкт`" також буде дійсним:

```JSON
{
    "name": "Foo",
    "price": 45.2
}
```

Например, модель выше описывает вот такой JSON "объект" (или словарь Python):

```JSON
{
    "name": "Foo",
    "description": "An optional description",
    "price": 45.2,
    "tax": 3.5
}
```

...поскольку `description` и `tax` являются необязательными (с `None` в качестве значения по умолчанию), вот такой JSON "объект" также подходит:

```JSON
{
    "name": "Foo",
    "price": 45.2
}
```
