javaweb学习笔记-response

一、乱码

response.setCharacterEncoding("utf-8");
response.setContentType("text/html;charset=utf-8");
response.getWriter().write("中国");

二、文件下载

url编码一下防止乱码

response.setHeader("content-disposition", "attachment;filename="+URLEncoder.encode("梅花.jpg", "utf-8"));

三、重定向

response.sendRedirect("/index.jsp");
