## Add regular expressions { #add-regular-expressions }

You can define a <abbr title="A regular expression, regex or regexp is a sequence of characters that define a search pattern for strings.">regular expression</abbr> `pattern` that the parameter should match:

## 总结

你可以为查询参数声明额外的校验和元数据。

通用的校验和元数据：

* `alias`
* `title`
* `description`
* `deprecated`

特定于字符串的校验：

* `min_length`
* `max_length`
* `regex`

在这些示例中，你了解了如何声明对 `str` 值的校验。
