這種情況下，你可以設定 `response_model=None` 來停用回應模型的產生：

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

這會讓 FastAPI 略過回應模型的產生，如此你就能使用任何你需要的回傳型別註解，而不會影響你的 FastAPI 應用程式。🤓

## 回應模型編碼參數 { #response-model-encoding-parameters }

你的回應模型可能有預設值，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`）預設為 `None`。

De la même façon, vous pouvez déclarer des paramètres de requête optionnels, en définissant leur valeur par défaut à `None` :

{* ../../docs_src/query_params/tutorial002_py310.py hl[7] *}

Dans ce cas, le paramètre de fonction `q` sera optionnel et vaudra `None` par défaut.
