很简单，没什么好说的，直接上代码：

 

package httpclienttest;

import org.apache.commons.httpclient.Cookie;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.NameValuePair;
import org.apache.commons.httpclient.methods.GetMethod;
import org.apache.commons.httpclient.methods.PostMethod;

public class LoginKaixin {
	private static final String LOGON_SITE = "http://www.kaixin001.com";
	private static final int LOGON_PORT = 80;
	public static void main(String[] args)throws Exception {
		HttpClient client = new HttpClient();
		client.getHostConfiguration().setHost(LOGON_SITE, LOGON_PORT);
		
		//登录页面
		PostMethod post = new PostMethod("http://www.kaixin001.com/login/login.php");
		NameValuePair ie = new NameValuePair("User-Agent","Mozilla/4.0 (compatible; MSIE 6.0; Windows 2000)");   
		NameValuePair url = new NameValuePair("url", "/home/");
		NameValuePair username = new NameValuePair("email","[email protected]");
		NameValuePair password = new NameValuePair("password", "xxxxxx");
	post.setRequestBody(new NameValuePair[] { ie,url,username, password});
		client.executeMethod(post);
		System.out.println("******************************登录******************************");
		Cookie[] cookies = client.getState().getCookies();
		client.getState().addCookies(cookies);
		post.releaseConnection();
		System.out.println("******************************页面转向******************************");
		String newUrl="http://www.kaixin001.com/home/";
		System.out.println("==========Cookies============");
		int i=0;
		for(Cookie c:cookies){
			System.out.println(++i+":	"+c);
		}
		client.getState().addCookies(cookies);
		post.releaseConnection();
		GetMethod get = new GetMethod(newUrl);
		get.setRequestHeader("Cookie", cookies.toString());
		client.executeMethod(get);
		String responseString = get.getResponseBodyAsString();
		//登录后首页的内容
		System.out.println(responseString);
		get.releaseConnection();
		System.out.println("******************************组件功能******************************");
		//"http://www.kaixin001.com/!slave/index.php", "朋友买卖"
		//"http://www.kaixin001.com/!parking/index.php", "争车位"

		//(1)进入朋友买卖****************
		System.out.println("******************************(1)进入朋友买卖******************************");
		String slave="http://www.kaixin001.com/!slave/index.php";
		get = new GetMethod(slave);
		get.setRequestHeader("Cookie", cookies.toString());
		client.executeMethod(get);
		responseString = get.getResponseBodyAsString();
		System.out.println(responseString);
		get.releaseConnection();
		//(2)进入争车位****************
		System.out.println("******************************(2)进入争车位******************************");
		String parking="http://www.kaixin001.com/!parking/index.php";
		get = new GetMethod(parking);
		get.setRequestHeader("Cookie", cookies.toString());
		client.executeMethod(get);
		responseString = get.getResponseBodyAsString();
		System.out.println(responseString);
		get.releaseConnection();
		//(3)进入买房子****************
		System.out.println("******************************(3)进入买房子*******************************");
		String house="http://www.kaixin001.com/!house/index.php?_lgmode=pri&t=49";
		get = new GetMethod(house);
		get.setRequestHeader("Cookie", cookies.toString());
		client.executeMethod(get);
		responseString = get.getResponseBodyAsString();
		System.out.println(responseString);
		get.releaseConnection();
		//(4)进入花园****************
		System.out.println("******************************(4)进入花园*******************************");
		String garden="http://www.kaixin001.com/!house/garden/index.php";
		get = new GetMethod(garden);
		get.setRequestHeader("Cookie", cookies.toString());
		client.executeMethod(get);
		responseString = get.getResponseBodyAsString();
		System.out.println(responseString);
		get.releaseConnection();
		
		
	}

}
