问题描述

我想要一个正则表达式来检查:

I want a regular expression to check that:

密码至少包含八个字符，包括至少一个数字，同时包含大小写字母和特殊字符，例如#、?、!.

A password contains at least eight characters, including at least one number and includes both lower and uppercase letters and special characters, for example #, ?, !.

它不能是您的旧密码或包含您的用户名、"password" 或 "websitename"

It cannot be your old password or contain your username, "password", or "websitename"

这是我的验证表达式，它适用于八个字符，包括一个大写字母、一个小写字母和一个数字或特殊字符.

And here is my validation expression which is for eight characters including one uppercase letter, one lowercase letter, and one number or special character.

(?=^.{8,}$)((?=.*d)|(?=.*W+))(?![.
])(?=.*[A-Z])(?=.*[a-z]).*$"

密码必须是八个字符，包括一个大写字母、一个特殊字符和字母数字字符?

推荐答案

最少八个字符，至少一个字母和一个数字:

"^(?=.*[A-Za-z])(?=.*d)[A-Za-zd]{8,}$"

最少八个字符，至少一个字母、一个数字和一个特殊字符:

Minimum eight characters, at least one letter, one number and one special character:

"^(?=.*[A-Za-z])(?=.*d)(?=.*[@$!%*#?&])[A-Za-zd@$!%*#?&]{8,}$"

最少八个字符，至少一个大写字母、一个小写字母和一个数字:

Minimum eight characters, at least one uppercase letter, one lowercase letter and one number:

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

最少八个字符，至少一个大写字母，一个小写字母，一个数字和一个特殊字符:

Minimum eight characters, at least one uppercase letter, one lowercase letter, one number and one special character:

"^(?=.*[a-z])(?=.*[A-Z])(?=.*d)(?=.*[@$!%*?&])[A-Za-zd@$!%*?&]{8,}$"

最少 8 个字符，最多 10 个字符，至少 1 个大写字母、1 个小写字母、1 个数字和 1 个特殊字符:
