java - 下载文件中的 UTF-8 编码名称

Question

我正在尝试让用户下载带有日文名称的 excel 文件。似乎它只适用于 IE 8，而其他 IE 和 firefox 则不起作用。请建议我如何处理这个。

String fileName = dateString+"_マイページ情報.xls";
byte[] data = writer.getData();
response.setContentType("application/ms-excel");
response.setContentLength(data.length);
response.setHeader("Expires:", "0"); // eliminates browser caching
response.setHeader("Content-Disposition","attachment; filename="+URLEncoder.encode(fileName));

Answer 1

我解决了如下。

fileName = dateString+"_マイページ情報.xls"; 
fileName = URLEncoder.encode(fileName,"UTF-8"); 
try {
        response.setContentType("application/ms-excel; charset=UTF-8");
        response.setCharacterEncoding("UTF-8");
        if(browserType.equals("IE")||browserType.equals("Chrome"))
            response.setHeader("Content-Disposition","attachment; filename="+fileName);
        if(browserType.endsWith("Firefox"))
            response.setHeader("Content-Disposition","attachment; filename*=UTF-8''"+fileName);
    } catch (Exception e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
