java.net.URL 模拟用户登录网页并维持session

半成品,并非完全有用

import java.io.BufferedReader;

import java.io.InputStreamReader;

import java.io.OutputStream;

import java.net.HttpURLConnection;

import java.net.URL;

public class SessionHolder {

    public static void main(String[] args) throws Exception {

        URL url = new URL("http://192.168.1.147:144/platformproxy/j_spring_security_check");

        HttpURLConnection connection = (HttpURLConnection) url.openConnection();

        connection.setDoOutput(true);// 允许连接提交信息

        connection.setRequestMethod("POST");// 网页提交方式“GET”、“POST”

        connection.setRequestProperty("User-Agent",    "Mozilla/4.7 [en] (Win98; I)");

        StringBuffer sb = new StringBuffer();

//        sb.append("username=admin");

//        sb.append("&password=admin");

        sb.append("j_username=09000001");

        sb.append("&j_password=zsinsgooda");

        OutputStream os = connection.getOutputStream();

        os.write(sb.toString().getBytes());

        os.close();

        BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));

        String responseCookie = connection.getHeaderField("Set-Cookie");// 取到所用的Cookie

        System.out.println("cookie:" + responseCookie);

        String line = br.readLine();

        while (line != null) {

            System.out.println(new String(line.getBytes()));

            line = br.readLine();// 打出登录的网页

        }

        // acces

        URL url1 = new URL("网页的登录后的页面");

        HttpURLConnection connection1 = (HttpURLConnection) url1.openConnection();

        connection1.setRequestProperty("Cookie", responseCookie);// 给服务器送登录后的cookie

        BufferedReader br1 = new BufferedReader(new InputStreamReader(connection1.getInputStream()));

        String line1 = br1.readLine();

        while (line1 != null) {

            System.out.println(new String(line1.getBytes()));

            line1 = br1.readLine();

        }

    }

}
