在这种情况下，你可以通过设置 `response_model=None` 来禁用响应模型生成：

{* ../../docs_src/response_model/tutorial003_05_py310.py hl[7] *}

这会让 FastAPI 跳过响应模型的生成，这样你就可以按需使用任意返回类型注解，而不会影响你的 FastAPI 应用。🤓

## 响应模型的编码参数 { #response-model-encoding-parameters }

你的响应模型可以具有默认值，例如：

{* ../../docs_src/response_model/tutorial004_py310.py hl[9,11:12] *}

* `description: Union[str, None] = None`（或在 Python 3.10 中的 `str | None = None`）默认值为 `None`。
