好的,从不同的浏览器下载文件时存在一些问题。我的示例关注 MSIE 和 Mozilla 类型的浏览器所需的处理
public HttpServletResponse getFile (HttpServletRequest request ,HttpServletResponse httpServletResponse, .......){
HttpServletResponse response = httpServletResponse;
InputStream in =/*HERE YOU READ YOUR FILE AS BinaryStream*/
String filename = "";
String agent = request.getHeader("USER-AGENT");
if (agent != null && agent.indexOf("MSIE") != -1)
{
filename = URLEncoder.encode(/*THIS IS THE FILENAME SHOWN TO THE USER*/, "UTF8");
response.setContentType("application/x-download");
response.setHeader("Content-Disposition","attachment;filename=" + filename);
}
else if ( agent != null && agent.indexOf("Mozilla") != -1)
{
response.setCharacterEncoding("UTF-8");
filename = MimeUtility.encodeText(/*THIS IS THE FILENAME SHOWN TO THE USER*/, "UTF8", "B");
response.setContentType("application/force-download");
response.addHeader("Content-Disposition", "attachment; filename=\"" + filename + "\"");
}
BufferedOutputStream out = new BufferedOutputStream(response.getOutputStream());
byte by[] = new byte[32768];
int index = in.read(by, 0, 32768);
while (index != -1) {
out.write(by, 0, index);
index = in.read(by, 0, 32768);
}
out.flush();
return response;
}
看一下这个
