可以把文件拖入指定区域，完成上传，同样支持点击上传。

import { Upload, Icon, message } from 'antd';
const Dragger = Upload.Dragger;

const props = {
  name: 'file',
  showUploadList: false,
  action: '/upload.do',
  onChange(info) {
    if (info.file.status !== 'uploading') {
      console.log(info.file, info.fileList);
    }
    if (info.file.status === 'done') {
      message.success(`${info.file.name} 上传成功。`);
    } else if (info.file.status === 'error') {
      message.error(`${info.file.name} 上传失败。`);
    }
  },
};
