ping @jahnli @jizai1125 是否有可能重新打开这个issue
考虑原生添加该属性去更开箱即用的提供上传文件大小限制功能?

  const beforeUpload = ({ file }: { file: UploadFileInfo; fileList: UploadFileInfo[] }) => {
    const fileSize = parseFloat(((file.file?.size ?? 0) / 1024 / 1024).toFixed(1));
    if (fileSize > astrictFileSize) {
      return false;
    }
    return true;
  };
