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.

  // verb=attest.
  //
  // If signerName is not empty, then the ClusterTrustBundle object must be
  // named with the signer name as a prefix (translating slashes to colons).
  // For example, for the signer name `example.com/foo`, valid
  // ClusterTrustBundle object names include `example.com:foo:abc` and
  // `example.com:foo:v1`.
  //
  // If signerName is empty, then the ClusterTrustBundle object's name must
  // not have such a prefix.
  //
