我这样设置:
response.setHeader("content-disposition", "attachment;filename=" + URLEncoder.encode("你好.txt", "utf-8"));
它适用于chrome,但不适用于firefox,在firefox中文件名为%E4%BD%A0%E5%A5%BD.txt
。
那么如何设置文件名?我想在chrome,firefox和IE(> = 8)
中正确显示文件名PS :由朋友解决,与您分享,也许可以帮助他人。
/**
return encoded file name
*/
protected String getFileName(String filename) {
try{
HttpServletRequest request = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();
if (request.getHeader("User-Agent").indexOf("MSIE") != -1) {
return '\"' + java.net.URLEncoder.encode(filename, "UTF-8") + '\"';
}
byte[] bytes = filename.getBytes("UTF-8");
StringBuilder buff = new StringBuilder(bytes.length << 2);
buff.append("=?UTF-8?Q?");
for (byte b : bytes) {
int unsignedByte = b & 0xFF;
buff.append('=').append(HEX_CHARS[unsignedByte >> 4]).append(HEX_CHARS[unsignedByte & 0xF]);
}
return buff.append("?=").toString();
}catch(UnsupportedEncodingException e){
return filename;
}
}
private static final char[] HEX_CHARS = new char[] { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B',
'C', 'D', 'E', 'F' };
我在chrom 33.0,IE 8和firefox 26.0中测试了这段代码,效果很好。

虽然这是旧帖,但我想分享我得到的解决方案。它可能会帮助某人。它就像IE 11,Chrome 48和Fire-Fox 38的魅力一样。以下是我在java代码中设置content-disposition
的方法 -
final String encodedFileName = encodeFilename(fileNameToEncode);
response.setHeader("Content-Disposition", "attachment; filename*=UTF-8''" + encodedFileName);
private String encodeFilename(final String filename)
{
try{
URI uri = new URI(null, null, filename, null);
String encodedName = uri.toASCIIString();
return encodedName;
}
catch(URISyntaxException ex){
return filename;
}
}
参考RFC以查看filename*=utf-8''

这是我使用的最终解决方案。(使用Spring MVC)
/**
return encoded file name
*/
protected String getFileName(String filename) {
try{
HttpServletRequest request = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();
if (request.getHeader("User-Agent").indexOf("MSIE") != -1) {
return '\"' + java.net.URLEncoder.encode(filename, "UTF-8") + '\"';
}
byte[] bytes = filename.getBytes("UTF-8");
StringBuilder buff = new StringBuilder(bytes.length << 2);
buff.append("=?UTF-8?Q?");
for (byte b : bytes) {
int unsignedByte = b & 0xFF;
buff.append('=').append(HEX_CHARS[unsignedByte >> 4]).append(HEX_CHARS[unsignedByte & 0xF]);
}
return buff.append("?=").toString();
}catch(UnsupportedEncodingException e){
return filename;
}
}
private static final char[] HEX_CHARS = new char[] { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B',
'C', 'D', 'E', 'F' };

使用java.net.URI。像这样改变你的代码
URI uri = new URI(null, null, "你好.txt", null);
String fileName = uri.toASCIIString();
response.setHeader("content-disposition", "attachment;filename=" + fileName);
