如何用reduxform计算？

import React from 'react';
import { reduxForm, Field } from 'redux-form';

// 表单验证规则
const validate = values => {
  const errors = {};
  if (!values.username) {
    errors.username = '用户名不能为空';
  }
  if (!values.password) {
    errors.password = '密码不能为空';
  }
  return errors;
};

// 表单提交处理函数
const handleSubmit = values => {
  // 处理表单提交逻辑
  console.log(values);
};

// 表单组件
const MyForm = props => {
  const { handleSubmit } = props;
  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label>用户名</label>
        <Field name="username" component="input" type="text" />
      </div>
      <div>
        <label>密码</label>
        <Field name="password" component="input" type="password" />
      </div>
      <button type="submit">提交</button>
    </form>
  );
};

// 连接Redux Store
const ConnectedForm = reduxForm({
  form: 'myForm',
  validate,
})(MyForm);

export default ConnectedForm;
