Android 實現Http get 和post操作

配置服務器

這個是我的Web實體

index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="gb2312"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
<h3>GET方法</h3>
<form action="Test" method="get">
<P>學號：<input name="id" type="text" /></P>
<p>姓名：<input name="name" type="text" /></p>
<p> <input name="" type="submit" value="確定" />
<input name="cancel" type="reset" value="取消" />
</p>
</form>
<h3>POST方法</h3>
<form action="Test" method="post">
<P>學號：<input name="id" type="text" /></P>
<p>姓名：<input name="name" type="text" /></p>
<p> <input name="" type="submit" value="確定" />
<input name="cancel" type="reset" value="取消" />
</p>
</form>
</body>
</html>

配置Servlet

Test.java

package rw.servlet;
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 Test extends HttpServlet {
/**
* The doGet method of the servlet. <br>
*
* This method is called when a form has its tag value method equals to get.
*
* @param request the request send by the client to the server
* @param response the response send by the server to the client
* @throws ServletException if an error occurred
* @throws IOException if an error occurred
*/
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("gb2312");
response.setContentType("text/html;charset=gb2312");
PrintWriter out = response.getWriter();
String idString=request.getParameter("id");
String nameString=request.getParameter("name");
out.println(idString);
out.println(nameString);
out.flush();
out.close();
}
/**
* The doPost method of the servlet. <br>
*
* This method is called when a form has its tag value method equals to post.
*
* @param request the request send by the client to the server
* @param response the response send by the server to the client
* @throws ServletException if an error occurred
* @throws IOException if an error occurred
*/
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("gb2312");
response.setContentType("text/html;charset=gb2312");
PrintWriter out = response.getWriter();
String idString=request.getParameter("id");
String nameString=request.getParameter("name");
out.println(idString);
out.println(nameString);
out.flush();
out.close();
}
}
