Get请求:
// 获取请求参数 String username = req.getParameter("username"); //1 先以 iso8859-1 进行编码 //2 再以 utf-8 进行解码 username = new String(username.getBytes("iso-8859-1"), "UTF-8");
Post请求:
@Override protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { // 设置请求体的字符集为 UTF-8 ,从而解决 post 请求的中文乱码问题 req.setCharacterEncoding("UTF-8"); System.out.println("-------------doPost------------"); // 获取请求参数 String username = req.getParameter("username"); String password = req.getParameter("password"); String[] hobby = req.getParameterValues("hobby"); System.out.println(" 用户名:" + username); System.out.println(" 密码:" + password); System.out.println(" 兴趣爱好:" + Arrays.asList(hobby)); }
// 它会同时设置服务器和客户端都使用 UTF-8 字符集,还设置了响应头 // 此方法一定要在获取流对象之前调用才有效 resp.setContentType("text/html; charset=UTF-8");
