我直接修改了org.zkoss.web.servlet.http包底下的Https类的encodeFilename方法也可以解决这个问题.

  1. private static String encodeFilename(String flnm) {
  2. String filename = Strings.escape(flnm, "\"") ;
  3. [color=red]try {
  4. filename =URLEncoder.encode(filename, "UTF-8");
  5. } catch (UnsupportedEncodingException e) {
  6. e.printStackTrace();
  7. }[/color]
  8. return '"' + filename+ '"';
  9. }

或者

  1. Execution ex = Executions.getCurrent();
  2. HttpServletRequest request = (HttpServletRequest) ex.getNativeRequest();
  3. if (request.getHeader("User-Agent").indexOf("MSIE") != -1) {// ie
  4. docFilename = URLEncoder.encode(docFilename, "UTF-8");
  5. } else {// firefox
  6. docFilename = MimeUtility.encodeText(docFilename, "GBK", "B");
  7. }
