Answer 1

这应该做到这一点:

(?=.*?[a-z])(?=.*?[A-Z])(?=.*?[^a-zA-Z]).{8,}

看到这里:rubular

解释:

(?=.*?[a-z]) //lookahead, there has to be a lower case alphabetic char
(?=.*?[A-Z]) //lookahead, there has to be a upper case alphabetic char
(?=.*?[^a-zA-Z]) //lookahead, there has to be a non-alphabetic char
.{8,} // any character at least 8 times
