本文介绍了一种在不同浏览器中实现文件下载的方法，特别是针对IE、火狐和Chrome等主流浏览器进行了兼容性处理。通过判断User-Agent来决定使用何种编码方式设置响应头，确保在各种浏览器环境下正确显示文件名。
支持IE和火狐 chrome
String agent = request.getHeader("User-Agent");
boolean isMSIE = (agent != null && agent.indexOf("MSIE") != -1);
if (isMSIE) {
zipName = URLEncoder.encode(zipName, "UTF-8");
}else{
zipName =new String(zipName.getBytes("UTF-8"), "ISO-8859-1");
}
response.setHeader("content-disposition", "attachment;filename=" + zipName);
String agent = request.getHeader("User-Agent");
boolean isMSIE = (agent != null && agent.indexOf("MSIE") != -1);
if (isMSIE) {
zipName = URLEncoder.encode(zipName, "UTF-8");
}else{
zipName =new String(zipName.getBytes("UTF-8"), "ISO-8859-1");
}
response.setHeader("content-disposition", "attachment;filename=" + zipName);
