需要一个正则表达式来验证以下字符串,如下所示。

'Earn extra 20%' - 有效

'Earn 20% extra' - 有效

'earn extra 20%' - 有效

'earn 20% extra' - 有效

'Earn 20' - 有效

'Earn ' - 无效

'20' - 无效

'Earn ^&' - 无效

不应允许使用任何其他特殊字符

  • 使用golang 1.19

'Earn extra 20%' - valid

'Earn 20% extra' - valid

使用(?i)(不区分大小写)标志和可选项的替代方案(而不是使用前后查找,go语言不支持):

(?i)earn (\d+%?( extra)?|extra \d+%?)

英文:

Use the (?i) (case insensitive) flag and an alternation with optional terms (instead of using look arounds, which go doesn't support):

(?i)earn (\d+%?( extra)?|extra \d+%?)

尝试这个:

regex := regexp.MustCompile(`^(?=.*\b赚\b|\b赚\b)(?=.*\b\d+\b|%)(?!.*[^a-zA-Z0-9%\s])`)

英文:

Try this:

regex := regexp.MustCompile(`^(?=.*\bEarn\b|\bearn\b)(?=.*\b\d+\b|%)(?!.*[^a-zA-Z0-9%\s])`)

答案3

得分: -1

请尝试以下内容:

^(?=[a-zA-Z0-9_ ]*(?i)earn[a-zA-Z0-9_ ]*)(?=[a-zA-Z0-9_ ]*(?i)extra[a-zA-Z0-9_ ]*)(?=[a-zA-Z0-9_ ]*20%?[a-zA-Z0-9_ ]*)

这将匹配以下内容:

  1. 字符串必须包含 earn、extra 和 20
  2. 20 后面可以有或没有 %
  3. 其他单词不应包含特殊字符(只允许数字和普通字符)
英文:

Try below,

^(?=[a-zA-Z0-9_ ]*(?i)earn[a-zA-Z0-9_ ]*)(?=[a-zA-Z0-9_ ]*(?i)extra[a-zA-Z0-9_ ]*)(?=[a-zA-Z0-9_ ]*20%?[a-zA-Z0-9_ ]*)

This will match -

  1. String which must have earn, extra and 20 in string
  2. With or without % after 20
  3. Other words should not contain the special character (only numbers and normal characters are allowed)
