Question

求助，Java下载功能的代码怎么无法弹出浏览器的下载框？

File file = new File(filePath);
String fileName = filePath.substring(filePath.lastIndexOf(File.separator) + 1);// 得到文件名
fileName = new String(fileName.getBytes("UTF-8"), "ISO8859-1");
System.out.println("fileNam="+fileName);
response.setContentType("application/octet-stream");
response.addHeader("Content-Disposition", "attachment;filename="+ fileName);
String len = String.valueOf(file.length());
response.setHeader("Content-Length", len);// 设置内容长度
OutputStream out = response.getOutputStream();
FileInputStream in = new FileInputStream(file);
byte[] b = new byte[1024];
int k;
while ((k = in.read(b)) != -1) {
out.write(b, 0, k);
}
in.close();
out.close();

答案是不能。如果是智能机一定支持Java功能，还另外支持像sis,sisx,exe等格式的，既然连Java功能不支持的，那么该手机就什么软件都没得下载安装的。
