validateRules: { certno: [ { required: true, message: '证件号码不能为空' }, { validator: (rule, value) => { return new Promise((resolve, reject) => { const result = verify(value); if (result.status === 0) { resolve(); } else { reject(new Error(result.msg)); } }); }, message: '请输入正确的身份证号码' } ], name: [ { required: true, message: '姓名不可为空' } ], empName: [ { required: true, message: '单位名称不可为空' } ], empCode: [ { required: true, message: '统一信用代码不能为空' }, { validator: (rule, value) => { return new Promise((resolve, reject) => { if (/^[A-Z0-9]{18}$/.test(value)) { resolve(); } else { reject(new Error('请输入正确的统一信用代码')); } }); } } ], reason: [ { required: true, message: '失信原因不能为空' } ] } 优化下这段代码

这段代码可以进行以下优化：

1. 使用正则表达式验证证件号码，不需要自己写验证函数。

2. 将验证函数提取为公共函数，避免重复代码。

3. 将验证规则抽离到单独的变量中，方便维护和修改。

4. 将多个验证规则合并为一条，减少代码量。

下面是优化后的代码：

const rules = {
  certno: [
    { required: true, message: '证件号码不能为空' },
    { pattern: /(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X|x)$)/, message: '请输入正确的身份证号码' }
  ],
  name: [
    { required: true, message: '姓名不可为空' }
  ],
  empName: [
    { required: true, message: '单位名称不可为空' }
  ],
  empCode: [
    { required: true, message: '统一信用代码不能为空' },
    { pattern: /^[A-Z0-9]{18}$/, message: '请输入正确的统一信用代码' }
  ],
  reason: [
    { required: true, message: '失信原因不能为空' }
  ]
};

const validateRules = {};
for (let key in rules) {
  validateRules[key] = rules[key].map(rule => {
    if (rule.validator) {
      return {
        validator: (rule, value) => {
          return new Promise((resolve, reject) => {
            const result = rule.validator(value);
            if (result.status === 0) {
              resolve();
            } else {
              reject(new Error(result.msg));
            }
          });
        },
        message: rule.message
      };
    } else {
      return rule;
    }
  });
}
