根据条件正则表达式 [英] Regular expression as per condition

问题描述

我需要按照以下标准定期表达



密码必须介于8到20个字符之间且至少有1个特殊字符（！@＃$ + =？* _ - ）1数字& 1个大写字母。



注意：特殊字符必须仅来自！@＃$ + =？* _-



我尝试了什么：



我试过（？= ^。{8,20} $） （？=。* \ d）（？=。* [AZ]）（？=。* [！@＃$&？* _-]）（？！。* \ s）。* $但它还允许其他字符。

解决方案

+ =？* _-）1数字& 1个大写字母。



注意：特殊字符必须仅来自！@＃

+ =？* _-



我尝试了什么：



我试过（？ = ^。{8,20}

）（？=。* \d）（？=。* [AZ]）（？=。* [！@＃

I need regular expresssion as per folllowing criteria

Password must be between 8-20 characters having atleast 1 special character(!@#$+=?*_-) 1 numeric & 1 upper case alphabet.

Note: special character must be only from "!@#$+=?*_-"

What I have tried:

I tried "(?=^.{8,20}$)(?=.*\d)(?=.*[A-Z])(?=.*[!@#$&?*_-])(?!.*\s).*$" but it is also allowing other characters.

解决方案

+=?*_-) 1 numeric & 1 upper case alphabet.

Note: special character must be only from "!@#

+=?*_-"

What I have tried:

I tried "(?=^.{8,20}

)(?=.*\d)(?=.*[A-Z])(?=.*[!@#
