推荐答案

想法和大部分工作取自

Idea and most of the work taken from http://www.zorched.net/2009/05/08/password-strength-validation-with-regular-expressions/

^\S*(?=\S{8,})(?=\S*[a-z])(?=\S*[A-Z])(?=\S*[\d])(?=\S*[\W])\S*$

我在其文章的底部使用了基本答案，但用\S替换了所有圆点以排除空格，然后在一些断言中移动.

I used the basic answer at the bottom of his post, but replaced all the dots with \S to rule out space characters, and moved around some of the assertions.
