## Регулярные выражения

Вы можете определить <abbr title="Регулярное выражение, regex или regexp - это последовательность символов, определяющая шаблон для строк.">регулярное выражение</abbr>, которому должен соответствовать параметр:

=== "Python 3.10+"

    ```Python hl_lines="11"

import java.util.concurrent.ThreadFactory;
import java.util.concurrent.ThreadPoolExecutor;
import java.util.concurrent.TimeUnit;
import java.util.concurrent.atomic.AtomicInteger;
import java.util.regex.Matcher;

  //   CamelCase names
  // - cloud provider specific error values must have names that comply with the
  //   format foo.example.com/CamelCase.
  // ---
  // The regex it matches is (dns1123SubdomainFmt/)?(qualifiedNameFmt)
  // +optional
  // +kubebuilder:validation:Required

## 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。
