因此，在使用 `Query` 的同时需要把某个值声明为必填时，只需不声明默认值：

{* ../../docs_src/query_params_str_validations/tutorial006_an_py310.py hl[9] *}

### 必填，但可以为 `None` { #required-can-be-none }

你可以声明一个参数可以接收 `None`，但它仍然是必填的。这将强制客户端必须发送一个值，即使该值是 `None`。

为此，你可以声明 `None` 是有效类型，但不声明默认值：

{* ../../docs_src/query_params_str_validations/tutorial006c_an_py310.py hl[9] *}
