我在网上看到了以下正则表达式.

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

它只在字符串中有效:

   * 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

* 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

特殊字符包括:

!`〜@#$%^&*()_- + = []\| …
