Тепер ми загорнемо її у `Annotated`, і отримаємо:

//// tab | Python 3.10+

```Python
q: Annotated[str | None] = None
```

////

//// tab | Python 3.8+

```Python
q: Annotated[Union[str, None]] = None
```

////

The query parameter `q` is of type `str | None`, that means that it's of type `str` but could also be `None`, and indeed, the default value is `None`, so FastAPI will know it's not required.

/// note

FastAPI will know that the value of `q` is not required because of the default value `= None`.

Having `str | None` will allow your editor to give you better support and detect errors.

///

El parámetro de query `q` es de tipo `str | None`, lo que significa que es de tipo `str` pero también podría ser `None`, y de hecho, el valor por defecto es `None`, así que FastAPI sabrá que no es requerido.

/// note | Nota

FastAPI sabrá que el valor de `q` no es requerido por el valor por defecto `= None`.

Tener `str | None` permitirá que tu editor te dé un mejor soporte y detecte errores.

///

由于我们必须用 `Query(default=None)` 替换默认值 `None`，`Query` 的第一个参数同样也是用于定义默认值。

所以：

```Python
q: Union[str, None] = Query(default=None)
```

...使得参数可选，等同于：

```Python
q: str = None
```

但是 `Query` 显式地将其声明为查询参数。

然后，我们可以将更多的参数传递给 `Query`。在本例中，适用于字符串的 `max_length` 参数：

```Python
q: Union[str, None] = Query(default=None, max_length=50)
```

将会校验数据，在数据无效时展示清晰的错误信息，并在 OpenAPI 模式的*路径操作*中记录该参​​数。

//// tab | Python 3.10+

```Python
q: str | None = None
```

////

//// tab | Python 3.9+

```Python
q: Union[str, None] = None
```

////

Мы «обернём» это в `Annotated`, и получится:

//// tab | Python 3.10+

```Python
q: Annotated[str | None] = None
```

////

//// tab | Python 3.9+

```Python
q: Annotated[Union[str, None]] = None
```

Der Query-Parameter `q` hat den Typ `str | None`, das bedeutet, dass er vom Typ `str` sein kann, aber auch `None`, und tatsächlich ist der Defaultwert `None`, sodass FastAPI weiß, dass er nicht erforderlich ist.

/// note | Hinweis

FastAPI erkennt, dass der Wert von `q` nicht erforderlich ist, aufgrund des Defaultwertes `= None`.

O parâmetro de consulta `q` é do tipo `str | None`, isso significa que é do tipo `str`, mas também pode ser `None`, e de fato, o valor padrão é `None`, então o FastAPI saberá que não é obrigatório.

/// note | Nota

O FastAPI saberá que o valor de `q` não é obrigatório por causa do valor padrão `= None`.

Ter `str | None` permitirá que seu editor lhe ofereça melhor suporte e detecte erros.
