java

package cn.web.request;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class Rdome5 extends HttpServlet {

    public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {

        //将[请求体]的中文以UTF-8方式重新编码
        request.setCharacterEncoding("UTF-8");
        ///this.getServletContext().getRequestDispatcher("/download.html").forward(request, response);

        String username = request.getParameter("username");
        String password = request.getParameter("password");
        String gender = request.getParameter("gender");
        String[] likes = request.getParameterValues("likes");
        String upfile = request.getParameter("upfile");
        String city = request.getParameter("city");
        String message = request.getParameter("message");
        String id = request.getParameter("id");

        //控制台输出
        System.out.println("username="+username);
        System.out.println("password="+password);
        System.out.println("gender="+gender);
        System.out.println("likes="+likes.length);
        System.out.println("upfile="+upfile);
        System.out.println("city="+city);
        System.out.println("message="+message);
        System.out.println("id="+id);
    }

}

结果:

username=234324
password=234
gender=male
likes=1
upfile=
city=bj
message=23432
id=20111008
username=234324
password=234
gender=male
likes=1
upfile=
city=bj
message=23432
id=20111008
