## 响应模型编码参数 你的响应模型可以具有默认值,例如: ```Python hl_lines="11 13-14" {!../../../docs_src/response_model/tutorial004.py!} ``` * `description: Union[str, None] = None` 具有默认值 `None`。 * `tax: float = 10.5` 具有默认值 `10.5`. * `tags: List[str] = []` 具有一个空列表作为默认值: `[]`. 但如果它们并没有存储实际的值,你可能想从结果中忽略它们的默认值。 举个例子,当你在 NoSQL 数据库中保存了具有许多可选属性的模型,但你又不想发送充满默认值的很长的 JSON 响应。
