redux-form 7强制复选框数组返回对象而不是数组

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

const CheckboxGroup = ({ options }) => (
  <div>
    {options.map(option => (
      <label key={option.value}>
        <Field
          name="checkboxGroup"
          component="input"
          type="checkbox"
          value={option.value}
          normalize={value => (value ? { [option.value]: true } : {})}
        />{' '}
        {option.label}
      </label>
    ))}
  </div>
);

const MyForm = props => {
  const { handleSubmit } = props;
  const options = [
    { label: 'Option 1', value: 'option1' },
    { label: 'Option 2', value: 'option2' },
    { label: 'Option 3', value: 'option3' },
  ];

  return (
    <form onSubmit={handleSubmit}>
      <CheckboxGroup options={options} />
      <button type="submit">Submit</button>
    </form>
  );
};

export default reduxForm({
  form: 'myForm',
})(MyForm);
