chrome Firefox 下载文件名乱码

Question

【背景】需求要求从服务器中下载已导出的用户信息Excel表格文件到用户本地
【代码】

   /**
    * 下载生成的所有在线/离线用户信息表格
    * @param request
    * @param response
    * @return 压缩文件
    * @throws FTPConnectionClosedException
    * @throws IOException
    */
   public File downloadExcel (HttpServletRequest request, HttpServletResponse response)
                throws FTPConnectionClosedException, IOException {
    File file = new File(zipPath);
    FileOutputStream fos = new FileOutputStream(file);
    ZipUtils.toZip(path, fos, true);
    //1.获取要下载的文件的绝对路径
    String realPath = zipPath;
    //2.获取要下载的文件名
    String fileName = realPath.substring(realPath.lastIndexOf(File.separator)+1);
    response.reset();
    response.setCharacterEncoding("UTF-8");
    response.setContentType("multipart/form-data");
    //3.设置content-disposition响应头控制浏览器以下载的形式打开文件
    response.addHeader("Content-Disposition","attachment;filename=" + new String(fileName.getBytes(),"utf-8"));
    //获取文件输入流
    InputStream in = new FileInputStream(realPath);
    int len = 0;
    byte[] buffer = new byte[1024];
    OutputStream out = response.getOutputStream();
    while ((len = in.read(buffer)) > 0) {
          //将缓冲区的数据输出到客户端浏览器
        out.write(buffer,0,len);
    }
    in.close();
         return file;
   }

【问题】如何将乱码转换为正常的中文？

Answer 1

尝试一：https://segmentfault.com/a/11... 按照此链接中的标准设定HTTP头字段Content-Disposition未奏效；

Answer 2

fileName = URLEncoder.encode(fileName, "UTF-8");
response.setHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\"");
response.setContentType("application/octet-stream;charset=UTF-8");  

换成这样的方式试一下看看。

Answer 3

    response.addHeader("Content-Disposition","attachment;filename=" + new String(fileName.getBytes(),"utf-8"));

utf-8换成iso8859-1试试
