似乎很直接的东西供您编写.如果您是我，我会先验证长度-不过请继续进行验证，因为您应该将所有问题报告给用户.然后，您可以使用三个简单的正则表达式查看是否有任何匹配项(其他条件中的每一个都匹配).

Seems a pretty straight forward thing for you to write. If I were you, I''d start by validating the length - keep going with the validation though, as you should report all the problems to the user. Then you can use three simple regular expressions to see if you have any matches (one for each of the other conditions).
