- servlet本地项目下载没问题，部署到服务器的下载文件名乱码
-
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { OutputStream out = null; // 输出响应正文的输出流 InputStream in = null; // 读取本地文件的输入流 // 获取filename请求参数 String filename = request.getParameter("filename"); String filepath = request.getParameter("filepath"); if (null == filename) { out = response.getOutputStream(); out.write("Please input filename.".getBytes()); out.close(); return; } filename=new String(filename.getBytes("ISO-8859-1"),"UTF-8"); UploadConfiguration cfg = UploadConfiguration.getConfiguration(); String realPath = cfg.getPhysicalPath(filepath); // 获得读取本地文件的输入流 in = new FileInputStream(new File(realPath)); int length = in.available(); // 设置响应正文的MIME类型 response.setContentType("application/force-download"); response.setHeader("Content-length", String.valueOf(length)); response.setHeader("Content-Disposition", "attachment;filename=\"" + BumfUtils.toUtf8String(filename) + "\" "); response.setHeader("ContentType","text/html;charset=UTF-8"); // 把本地文件中的数据发送给客户 out = response.getOutputStream(); int bytesRead = 0; byte[] buffer = new byte[512]; while ((bytesRead = in.read(buffer)) != -1) { out.write(buffer, 0, bytesRead); }
这个理是util
public static String toUtf8String(String s) {
StringBuffer sb = new StringBuffer();
for (int i=0;i<s.length();i++) {
char c = s.charAt(i);
if (c >= 0 && c <= 255) {
sb.append(c);
} else {
byte[] b;
try {
b = Character.toString(c).getBytes("utf-8");
} catch (Exception ex) {
System.out.println(ex);
b = new byte[0];
}
for (int j = 0; j < b.length; j++) {
int k = b[j];
if (k < 0) k += 256;
sb.append("%" + Integer.toHexString(k).
toUpperCase());
}
}
}
return sb.toString();
}
