React Hooks父组件中获取子组件Antd Form的fi

根据官网给出的实例，可以通过useImperativeHandle将子组件中props.form.getFieldsValue()暴露给父组件，从而在父组件中就可以拿到表单值，代码如下：（注：代码只是作为方法示例，不作为可运行实例）
父组件

import React, { 
  useRef
} from 'react'

import { Modal } from 'antd'
import MyForm from './myForm'

const ParentComp = () => {

    const getFormValue = useRef();

    const handleOk = () => {
      const fields = getFormValue.current.formFields;
      console.log(fields)
    }

    return <Modal onOk={handleOk} >
             <MyForm
               wrappedComponentRef={getFormValue}
             />
           </Modal>
}

export default ParentComp 

子组件(myForm.jsx)

import React, { useImperativeHandle, useRef, forwardRef } from 'react'
import { Form } from 'antd'

const MyForm = (props, ref) => {
  const formRef = useRef()

  useImperativeHandle(ref, () => ({
    formFields: props.form.getFieldsValue()
  }))

  return <Form ref={formRef}>
     ...
  </Form>
}

const WrappedForm = Form.create({ name: 'form' })(forwardRef(MyForm))

export default WrappedForm
