如何在joi

问题描述

当我验证graphql参数时，我在密码字段中收到了这样的错误消息。

"password" with value "" fails to match the required pattern: /^(?=\\S*[a-z])(?=\\S*[A-Z])(?=\\S*\\d)(?=\\S*[^\\w\\s])\\S{8,30}$/"

我不想在错误消息中显示正则表达式模式。因此，我尝试为密码字段设置自定义错误消息，但仍显示正则表达式模式。

import Joi from "joi";

export default Joi.object().keys({
  email: Joi.string().email().required().label("Email"),username: Joi.string().alphanum().min(4).max(20).required().label("Username"),name: Joi.string().min(4).max(256).required().label("Name"),password: Joi.string()
    .min(8)
    .regex(/^(?=\S*[a-z])(?=\S*[A-Z])(?=\S*\d)(?=\S*[^\w\s])\S{8,30}$/)
    .required()
    .label("Password")
    .messages({
      "string.min": "Must have at least 8 characters","object.regex": "Must have at least 8 characters",}),});

我认为它不是通过object.regex选择正则表达式。请帮忙。

解决方法

要知道抛出了什么错误，可以调试错误对象（通过记录错误对象），然后找到错误type。

示例：

const Joi = require('@hapi/joi');

const joiSchema = Joi.object().keys({
  password: Joi.string()
    .min(8)
    .regex(/^(?=\S*[a-z])(?=\S*[A-Z])(?=\S*\d)(?=\S*[^\w\s])\S{8,30}$/)
    .required()
    .label("Password")
    .messages({
      "string.min": "Must have at least 8 characters","object.regex": "Must have at least 8 characters","string.pattern.base": "enter your custom error here..."
    })
});

const validationResult = joiSchema.validate({ password: "2" },{ abortEarly: false });
console.log(validationResult.error.details.map(errDetail => errDetail.type),validationResult.error);

这将输出["string.min","string.pattern.base"]。由于string.min和string.pattern.base，details有2个错误，并且abortEarly设置为false。
