通过表单收集客户机数据

先写好表单的html页面form.html

<!DOCTYPE html>
<html>
  <head>
    <title>form.html</title>
	
    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
    <meta http-equiv="description" content="this is my page">
    <meta http-equiv="content-type" content="text/html; charset=UTF-8">
    
    <!--<link rel="stylesheet" type="text/css" href="./styles.css">-->

  </head>
  
  <body>
    <form action="/RequestTest/servlet/GetFormInf" method="post">
		UserName: <input type="text" name="username"></br>
		
		PassWord: <input type="password" name="password"></br>
		
		Gender:   <input type="radio" name="gender" value="male">male
		         <input type="radio" name="gender" value="female">female</br>
				 
		City:     <select name="city">
					<option value="bj">Beijing</option>
					<option value="sh">Shanghai</option>
					<option value="zz">Zhengzhou</option>
				  </select>
				  </br>
				 
		Likes:    <input type="checkbox" name="likes" value="sing">Sing
				  <input type="checkbox" name="likes" value="dance">Dance
				  <input type="checkbox" name="likes" value="basketball">BasketBall
				  <input type="checkbox" name="likes" value="football">Football
				  </br>
		Description: <textarea rows="6" cols="60" name="description"></textarea></br>
		
		<!--隐藏输入项-->
		<input type="hidden" name="id" value="123456">
		
			     <input type="submit" value="submit">
	</form>
  </body>
</html>

再写好GetFormInf.java

package RequestDemo;

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 GetFormInf extends HttpServlet
{
	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException
	{
		System.out.println(request.getParameter("username"));
		System.out.println(request.getParameter("password"));
		System.out.println(request.getParameter("gender"));
		System.out.println(request.getParameter("city"));
		String[] likeString = request.getParameterValues("likes");
		for(int i=0;likeString!=null && i<likeString.length;i++)
		{
			System.out.println(likeString[i]);
		}
		System.out.println(request.getParameter("description"));
	}

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

}

在浏览器中浏览form.html,如下图所示:
