你可以设置*路径操作装饰器*的 `response_model_exclude_unset=True` 参数：

```Python hl_lines="24"
{!../../docs_src/response_model/tutorial004.py!}
```

然后响应中将不会包含那些默认值，而是仅有实际设置的值。

因此，如果你向*路径操作*发送 ID 为 `foo` 的商品的请求，则响应（不包括默认值）将为：

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

/// info

// 	}
//
// // On the wire, the JSON will look something like this:
//
// 	{
// 		"kind":"MyAPIObject",
// 		"apiVersion":"v1",
// 		"myPlugin": {
// 			"kind":"PluginA",
// 			"aOption":"foo",
// 		},
// 	}
//
// So what happens? Decode first uses json or yaml to unmarshal the serialized data into
// your external MyAPIObject. That causes the raw JSON to be stored, but not unpacked.

			prefix:      "foodir/foobject/foo.txt",
			want:        true,
		},
		{
			inputConfig: `<LifecycleConfiguration><Rule><Status>Enabled</Status><Filter></Filter><NoncurrentVersionTransition><StorageClass>S3TIER-1</StorageClass></NoncurrentVersionTransition></Rule></LifecycleConfiguration>`,
			prefix:      "foodir/foobject/foo.txt",
			want:        true,
		},
		{

예를 들면, 위의 이 모델은 JSON "`object`" (혹은 파이썬 `dict`)을 다음과 같이 선언합니다:

```JSON
{
    "name": "Foo",
    "description": "선택적인 설명란",
    "price": 45.2,
    "tax": 3.5
}
```

...`description`과 `tax`는 (기본 값이 `None`으로 되어 있어) 선택적이기 때문에, 이 JSON "`object`"는 다음과 같은 상황에서도 유효합니다:

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