 const fileView1 = async (row: any) => {
    const options = {
      method: 'GET',
      url: '/udp-file/doc/file/download',
      params: { fileIds: row.fileId },
      headers: {
        'User-Token': token1,
      },
      withCredentials: true,
      responseType: 'blob',
    };
    try {
      const response = await axios.request(options);
      const url = window.URL.createObjectURL(new Blob([response.data]));
      const link = document.createElement('a');
      link.href = url;
      link.setAttribute('download', row.fileName);
      document.body.appendChild(link);
      link.click();
      link.parentNode.removeChild(link);
    } catch (error) {
      console.error(error);
    }
    console.log(err);
  };

responseType: 'blob',特别是这个属性这个属性不加上代码就会出现问题，会出现上传的文件下载下来打不开的情况
