``` #### Using `Union` or `Optional` If you are using a Python version below 3.10, here's a tip from my very **subjective** point of view: * 🚨 Avoid using `Optional[SomeType]` * Instead ✨ **use `Union[SomeType, None]`** ✨.

```Python hl_lines="1 4" {!../../../docs_src/python_types/tutorial009.py!} ``` Sử dụng `Optional[str]` thay cho `str` sẽ cho phép trình soạn thảo giúp bạn phát hiện các lỗi mà bạn có thể gặp như một giá trị luôn là một `str`, trong khi thực tế nó rất có thể là `None`.

* パラメータが **Pydantic モデル**型で宣言された場合、リクエスト**ボディ**として解釈されます。 !!! note "備考" FastAPIは、`= None`があるおかげで、`q`がオプショナルだとわかります。 `Optional[str]` の`Optional` はFastAPIでは使用されていません(FastAPIは`str`の部分のみ使用します)。しかし、`Optional[str]` はエディタがコードのエラーを見つけるのを助けてくれます。 ## Pydanticを使わない方法

``` `OAuth2PasswordRequestForm` is a class dependency that declares a form body with: * The `username`. * The `password`. * An optional `scope` field as a big string, composed of strings separated by spaces. * An optional `grant_type`. !!! tip The OAuth2 spec actually *requires* a field `grant_type` with a fixed value of `password`, but `OAuth2PasswordRequestForm` doesn't enforce it.

#### Possibly `None` (Optional) Ви можете оголосити, що значення може мати тип, наприклад `str`, але також може бути `None`. У Python 3.6 і вище (включаючи Python 3.10) ви можете оголосити його, імпортувавши та використовуючи `Optional` з модуля `typing`. ```Python hl_lines="1 4" {!../../../docs_src/python_types/tutorial009.py!} ```

- 类型是(`int`、`float`、`str`、`bool` 等)**单类型**的参数,是**查询**参数 - 类型是 **Pydantic 模型**的参数,是**请求体** !!! note "笔记" 因为默认值是 `None`, FastAPI 会把 `q` 当作可选参数。 FastAPI 不使用 `Optional[str]` 中的 `Optional`, 但 `Optional` 可以让编辑器提供更好的支持,并检测错误。 ## 不使用 Pydantic
