JAVA利用httpclient登录开心网

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 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();
