蚂蚁设计上传到dag文件后模态没有显示

ant design file drag and drop upload 和 modal . 我试着做的时候,我拖或上传文件的时刻,只是在屏幕上显示模式弹出(不想显示上传的文件,只是显示模式),我设置的代码,但它不工作,任何人都知道如何正确地做到这一点

谢谢

这里是代码部分

import { Upload, message,Modal, Button  } from 'antd';
import { InboxOutlined } from '@ant-design/icons';
const { Dragger } = Upload;

const props = {
  name: 'file',
  multiple: true,
  action: 'https://www.mocky.io/v2/5cc8019d300000980a055e76',
  onChange(info) {
    const { status } = info.file;
    if (status !== 'uploading') {
      console.log(info.file, info.fileList);
    }
    if (status === 'done') {
      message.success(`${info.file.name} file uploaded successfully.`);
    } else if (status === 'error') {
      message.error(`${info.file.name} file upload failed.`);
    }
  },
};
interface AppProps { }
interface AppState {
  name: string; 

}

class App extends Component<AppProps, AppState> {
  constructor(props) {
    super(props);
    this.state = {
      name: 'React',
     visible: false
    };
  }

  //modal
 

  showModal = (any) => {
    this.setState({
      visible: "true",
    });
  };

  handleOk = e => {
    console.log(e);
    this.setState({
      visible: false,
    });
  };

  handleCancel = e => {
    console.log(e);
    this.setState({
      visible: false,
    });
  };


    

  render() {
    return (
