httpclient简单应用，登录开心网的例子 需要用到的java包 commons-httpclient-3.1.jar commons-logging.jar log4j-1.2.15.jar commons-codec.jar 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","[e-mail]"); 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" //"http://www.kaixin001.com/!house/index.php?_lgmode=pri", "买房子" //http://www.kaixin001.com/!house/index.php?_lgmode=pri&t=49 //"http://www.kaixin001.com/!house/garden/index.php","花园" //(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(); } }
