Joi Regex 未被识别为正则表达式模式

Question

我正在尝试为密码字段制定一个验证规则，它应该包含以下内容：

• 必须有编号
• 必须至少包含一个大写字母
• 必须至少包含一个小写字母
• 必须包含以下任何符号 [@$!]
• 应仅包含 8 到 20 个字符。

这是我使用的正则表达式模式： (?=.*[az])(?=.*[AZ])(?=.*\d)(?=.*[$@$.#?])[A-Za-z\d$@$.%*,&.]{8,20}

在https://regexr.com/上测试

这是 Joi 验证：

password: Joi.string()
.regex(
  '/(?=.*[a-z])(?=.*[A-Z])(?=.*d)(?=.*[$@$!#.])[A-Za-zd$@$!%*?&.]{8,20}/'
)
.required()
.min(8)
.max(20)

错误堆栈跟踪：

Answer 1

我知道已经过去了大约 2 年，但我认为迟到总比不来好🤣🤣。

您只需要将模式放入RegExp()

这就是我编辑您的代码的方式:)

const pattern = "/(?=.*[a-z])(?=.*[A-Z])(?=.*d)(?=.*[$@$!#.])[A-Za-zd$@$!%*?&.]{8,20}/";

password: Joi.string()
.regex(RegExp(pattern)) // you have to put it in this way and it will work :)
.required()
.min(8)
.max(20)

我希望它能帮助你！

正则表达式不需要字符串中的任何单引号（开始/结束）

这是一个工作正常的例子。

const joi = require("joi");

const strongPasswordRegex = /^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$%^&*-]).{8,}$/;
const stringPassswordError = new Error("Password must be strong. At least one upper case alphabet. At least one lower case alphabet. At least one digit. At least one special character. Minimum eight in length")

const schema = joi.object().keys({
    username: joi.string().required().min(4).max(15),
    password: joi.string().regex(strongPasswordRegex).error(stringPassswordError).required()
});

const notValid = schema.validate({ username: "MHamzaRajput", password: "Admin@admin123" }).error;

if (notValid) {
    console.log(notValid.message);
} else {
    console.log("payload validated successfully");
}
