我已经在网上看到以下正则表达式。

(?=^.{8,}$)((?=.*\d)|(?=.*\W+))(?![.\n])(?=.*[A-Z])(?=.*[a-z]).*$

仅当字符串：

   * contain at least (1) upper case letter
   * contain at least (1) lower case letter
   * contain at least (1) number or special character
   * contain at least (8) characters in length

我想知道如何转换此正则表达式，以便将字符串检查为

* contain at least (2) upper case letter
* contain at least (2) lower case letter
* contain at least (2) digits
* contain at least (2) special character
* contain at least (8) characters in length

好吧，如果它至少包含2个大写，小写，数字和特殊字符，那么我就不需要8个字符的长度。

特殊字符包括：

`〜！@＃$％^＆*（）_- + = [] \ | {} ;:’“。，/ <>？
