你还可以添加 `min_length` 参数：

{* ../../docs_src/query_params_str_validations/tutorial003_an_py310.py hl[10] *}

## 添加正则表达式 { #add-regular-expressions }

你可以定义一个参数必须匹配的 <dfn title="正则表达式（regex 或 regexp）是用于定义字符串搜索模式的字符序列。">正则表达式</dfn> `pattern`：

{* ../../docs_src/query_params_str_validations/tutorial004_an_py310.py hl[11] *}

这个特定的正则表达式通过以下规则检查接收到的参数值：

- `^`：必须以接下来的字符开头，前面没有其他字符。
