问题描述

如何检查变量是否包含有效的UUID / GUID标识符？

How to check if variable contains valid UUID/GUID identifier ?

我目前只对验证类型1和4感兴趣，但它不是对你的答案的限制。

I'm currently interested only in validating types 1 and 4, but it's not limit for your answer.

推荐答案

目前，UUID是在RFC4122中指定的。

Currently, UUID's are as specified in RFC4122.

因此要验证UUID ......

Therefore to validate a UUID...

/^[0-9a-f]{8}-[0-9a-f]{4}-[1-5][0-9a-f]{3}-[89ab][0-9a-f]{3}-[0-9a-f]{12}$/i

...确保您拥有版本1到5的规范格式化UUID，并且是适当的变体根据RFC4122。

...ensures you have a canonically formatted UUID that is Version 1 through 5 and is the appropriate Variant as per RFC4122.

注意：大括号 {和} 不是规范的。它们是某些系统和用法的工件。

NOTE: Braces { and } are not canonical. They are an artifact of some systems and usages.

易于修改上述正则表达式以满足原始问题的要求。

Easy to modify the above regex to meet the requirements of the original question.

提示：正则表达式组/捕获
