React ref返回一个'Connect'对象而不是DOM

我正在尝试为通过map函数创建的自定义组件创建动态参考.

class PostsList extends Component {

  constructor(props) {
    super(props);
  }

  componentDidUpdate = () => {
    console.log(this.refs);
  }

  render() {
    let posts = this.props.posts || [];
    return (
        

          {posts.map((post) => {
            return 
          })}
        
    );
  }

}

export default PostsList

connect(null, null, null, { withRef: true })(Post);

this.refs[].getWrappedInstance()
