我尝试使用Struts 1下载xls文件,它在Firefox中运行,并使用阿拉伯名称下载该文件,但无法在Chrome中运行。

以下是代码:

public void download(CommandContext context, byte[] data, String filename) {
    String CONTENT_TYPE = "application/unknown";
    HttpServletResponse response = (HttpServletResponse) context
            .get(context.RESPONSE_KEY);
    try {

        response.setContentType(CONTENT_TYPE);
        response.setContentLength(data.length);
        String str = "attachment; filename=\""
                + new String(filename.getBytes("cp1256"), "cp1252") + "\"";
        response.setHeader("Content-Disposition", str);
        response.setHeader("Expires", "0");
        response.setHeader("Cache-Control",
                "must-revalidate, post-check=0, pre-check=0");
        response.setHeader("Pragma", "public");
        OutputStream outputStream = response.getOutputStream();

        outputStream.write(data);
        outputStream.flush();
        outputStream.close();

    } catch (IOException ex) {
        getLogger(this.getClass().getName()).error(
                "Can't download file of newly generated card numbers");

    }

}

当我按下载链接时,它会像这样下载:

答案 0 :(得分:1)

如果文件名包含new String(filename.getBytes("cp1256"), "cp1252")中不可用的字符,

cp1252将损坏文件名。即使它没有,那么结果只是偶然的。不要这样做。这总是错的。
