那位能两个简单的jsp页面，一个是发送一个接收
a页面要用HttpURLConnection对象 用数据流的形式post一个字符串变量到b页面
b页面 接收这个变量，并显示出来
[解决办法]
URL url = null; HttpURLConnection connection = null; int responseCode = 0; String responseMessage = ""; url = new URL("127.0.0.1:端口号"); connection = (HttpURLConnection)url.openConnection(); connection.setRequestMethod("POST"); connection.setRequestProperty("Content-Type","对应的类型"); connection.setRequestProperty("Content-Length",Integer.toString(str.getBytes().length) ); OutputStream out1=connection.getOutputStream(); String str=new String("aaaaaaaabbbbbb"); out1.write(str.getBytes()); out1.flush();
[解决办法]
用HttpURLConnection发送post请求并获取目标内容，例子如下：
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%><%@page import="java.net.URL"%><%@page import="java.net.HttpURLConnection"%><%@page import="java.io.DataInputStream"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html> <head> <title>test</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"> </head> <body> <% URL url = null; HttpURLConnection httpurlconnection = null; try { url = new URL("http://localhost:8080/xxx/testurlto.jsp"); httpurlconnection = (HttpURLConnection) url.openConnection(); httpurlconnection.setDoOutput(true); httpurlconnection.setRequestMethod("POST"); String username = "username=aaaaaa"; httpurlconnection.getOutputStream().write(username.getBytes()); httpurlconnection.getOutputStream().flush(); httpurlconnection.getOutputStream().close(); int code = httpurlconnection.getResponseCode(); String str = httpurlconnection.getResponseMessage(); DataInputStream inStream = new DataInputStream( httpurlconnection.getInputStream()); int ch; while ((ch = inStream.read()) >= 0) { System.out.print((char) ch); } } catch (Exception e) { e.printStackTrace(); } finally { if (httpurlconnection != null) httpurlconnection.disconnect(); } %> </body></html>
