Java本地化文件名 [英] Java localized filenames

问题描述

如何在java.Current中设置本地化的文件名每次我单击我的应用程序中具有非ascii文件名的本地化文件时，会弹出Windows保存对话框，但是如果字符集是任何东西，则不会正确显示文件名以上ISO-88859-1。

How can i set localized filenames in java.Currently everytime i click on a localized file having a non-ascii filename in my application, the windows save dialog box pops out, but it isnt displaying the filename properly if the charset is anything above ISO-88859-1.

这是我保存文件的代码。

This is my code which is saving the file.

            InputStream inputStream = null;
 try {
  response.resetBuffer();
  response.setContentType(fileStream.getContentType());
  response.setContentLength((int) fileStream.getContentLength());
  response.addHeader("Content-Disposition",
    "attachment;filename=\"" + fileName + "\"");
  ServletOutputStream stream = response.getOutputStream();
  byte[] buffer = new byte[1024];
  int read = 0;
  int total = 0;
  inputStream = fileStream.getInputStream();
  while ((read = inputStream.read(buffer)) > 0) {
   stream.write(buffer, 0, read);
   total += read;
  }
  response.flushBuffer();
 } finally {
  if (inputStream != null) {
   inputStream.close();
  }
 }

如果有人可以分享他们的想法，我会非常有帮助关于如何解决这个问题。
提前感谢

I would be very helpful if someone could share their ideas on how to resolve this issue. Thanks in advance.

推荐答案

什么gustafc说是正确的，但它不会让你在哪里是。 RFC 2231 允许您使用替代格式的非ASCII Content-键入和 Content-Disposition 参数，但不是所有的浏览器都支持它。不幸的是，最可能的方式是忽略RFC 2183所说的内容，并使用 RFC 2047编码字在回应中：

What gustafc says is correct, but it doesn't get you where you want to be. RFC 2231 allows you to use an alternative format for non-ASCII Content-Type and Content-Disposition parameters, but not all browsers support it. The way that's most likely to work, unfortunately, is to ignore what RFC 2183 says and use RFC 2047 encoded-words in the response:

response.addHeader("Content-Disposition", "attachment; " +
    "filename=\"" + MimeUtility.encodeWord(fileName, "utf-8", "Q") + "\"");

请注意，这可能不适用于所有浏览器。 IE的某些变体需要您将URL替换为值：

Note that this may not work for all browsers. Some variants of IE require that you URL-encode the value instead:

response.addHeader("Content-Disposition",
    "attachment; filename=" + URLEncoder.encode(filename, "utf-8"));
