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

Da `description` und `tax` optional sind (mit `None` als Defaultwert), wäre folgendes JSON „`object`“ auch gültig:

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

## Als Parameter deklarieren { #declare-it-as-a-parameter }

与声明查询参数一样，包含默认值的模型属性是可选的，否则就是必选的。默认值为 `None` 的模型属性也是可选的。

例如，上述模型声明如下 JSON **对象**（即 Python **字典**）：

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

……由于 `description` 和 `tax` 是可选的（默认值为 `None`），下面的 JSON **对象**也有效：

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

## 声明请求体参数

使用与声明路径和查询参数相同的方式声明请求体，把请求体添加至*路径操作*：

    VerifyException expected = assertThrows(VerifyException.class, () -> verify(false, FORMAT, 5));
    checkMessage(expected);
  }

  private static final String NON_NULL_STRING = "foo";

  public void testVerifyNotNull_simple_success() {
    String result = verifyNotNull(NON_NULL_STRING);
    assertSame(NON_NULL_STRING, result);
  }

  public void testVerifyNotNull_simple_failure() {

                "msg": "Field required",
                "input": None,
            }
        ]
    }


def test_post_body_json(client: TestClient):
    response = client.post("/files/", json={"file": "Foo"})
    assert response.status_code == 422, response.text
    assert response.json() == {
        "detail": [
            {
                "type": "missing",
                "loc": ["body", "file"],

	if [ $# -ne 0 ]; then
		exit $#
	fi
}

catch

function gen_put_request() {
	hdr_sleep=$1
	body_sleep=$2

	echo "PUT /testbucket/testobject HTTP/1.1"
	sleep $hdr_sleep
	echo "Host: foo-header"
	echo "User-Agent: curl/8.2.1"
	echo "Accept: */*"
	echo "Content-Length: 30"
	echo ""

	sleep $body_sleep
	echo "random line 0"
	echo "random line 1"
	echo ""
	echo ""
}

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

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

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
}
```
