为什么我的有效密码未通过Regex验证 [英] Why are my valid passwords not passing the Regex validation

问题描述

您好！



我正在编写密码屏幕，密码安全要求长度介于8到20个字符之间，必须至少包含一个字符阿尔法角色和至少一个数字角色和至少一个[！@＃$％^&*]的特殊角色。



我拼凑了这个正则表达式，它似乎在C＃中工作，但是当我开始重写代码进行javascript验证时，正则表达式将我认为有效密码标记为无效。



这里是正则表达式，因为我将它分配给RegExp：



var regExPatt = new RegExp（'^（？=（？：。* [a-zA-Z] ）{1}）（=（？：？* \d）{1}）（=（？：？？！* [！＃@@ $％^&*]）{1}）（* \ n）。{8,20} $'）;



*注意BENE：双@@符号用于将@符号输入RegExp，否则它试图处理部分字符串，如Razor变量和事情快速横向移动。



我在哪里这个正则表达式出错？我知道它相当复杂。



密码有效：freddy1234％，freddy123 $ 5，freddy12＃45，freddy1 @ 345，freddy！2345



不起作用的密码：test1234％，wilma1234％



有什么想法吗？



在此先感谢，

Hello!

I am writing a password screen, and the requirements for the password security are somewhere between 8 and 20 characters in length, must contain AT LEAST one Alpha character and AT LEAST one numeric character and AT LEAST one special character of [!@#$%^&*].

I have cobbled together this regular expression, which appeared to work in C#, but when I started rewriting the code for a javascript validation, the regular expression is flagging what I thought were valid passwords as invalid.

Here is the regular expression as I assign it to RegExp:

var regExPatt = new RegExp('^(?=(?:.*[a-zA-Z]){1})(?=(?:.*\d){1})(?=(?:.*[!@@#$%^&*]){1})(?!.*\s).{8,20}$');

*NOTE BENE: The double @@ symbol is there to get the @ symbol into the RegExp, otherwise it tries to treat partial strings like Razor variables and things go sideways fast.

Where did I go wrong with this regular expression? I know it is fairly complicated.

Passwords that work: freddy1234%, freddy123$5, freddy12#45, freddy1@345, freddy!2345

passwords that do not work: test1234%, wilma1234%

Any ideas?

Thanks in advance,

Andrew Giles
