今天做的一个简单投票程序

朋友让我帮忙做个刷票程序,原来打算从网上找个程序给他就算了,但登陆那个网站发现验证码是直接生成的文字...网上找到的都是对图片的处理....
想想其实,自己也可以做一个刷票程序...
于是写了以下代码,基本是参照网上的资料和api帮助文档....可惜最后对代理处理还是没成功,总是连接失败.....

import java.io.*;
import java.net.*;

public class shuapiao {
	String myurl="";//投票填写的url
	String sub_gdly="http://";//投票处理的url
	String session_id="";
	String id="";
	String proxyAddr="82.205.237.26";
	int proxyPost=8080;
	//HttpURLConnection conn = (HttpURLConnection)url.openConnection();
	public shuapiao(String myurl){
		this.myurl=myurl;
	}
	public String getUrl(){
		String valid="";
		try {
			InputStream   in;
			Proxy proxy=new Proxy(java.net.Proxy.Type.HTTP,new InetSocketAddress

(this.proxyAddr,this.proxyPost));
			URL url=new URL(myurl);
			HttpURLConnection conn = (HttpURLConnection)url.openConnection();//代理总连接不上,所以没用
			//int size = conn.getHeaderFields().size();
			conn.setDoOutput(true);
			conn.setRequestMethod("GET");
			conn.setRequestProperty("User-Agent","Mozilla/4.0 (compatible; MSIE 6.0; Windows 2000)");
			conn.setRequestProperty("host","www");//主机地址
			conn.setRequestProperty("Connection","keep-alive");//长连接,这个很好用!
			//HttpURLConnection connection = (HttpURLConnection)url.openConnection();
			conn.setRequestProperty("User-Agent","Mozilla/4.0 (compatible; MSIE 6.0; Windows 2000)");
			conn.connect();
		       in = conn.getInputStream();
		      java.io.BufferedReader breader =
		          new BufferedReader(new InputStreamReader(in , "GBK"));
		      String str=breader.readLine();
		      while(str != null){
		        System.out.println(str);
		        if(str.indexOf("验证码：<input type=\"text\" name=\"verifycode\" size=\"4\" /><font color=

\"#0000FF\" face=\"Georgia, Times New Roman, Times, serif\" size=\"3\"><i><b>")>-1){
		        	valid=str.substring(str.indexOf("<b>")+3, str.indexOf("</b>"));
		        }
		         str=breader.readLine();
		      }
		      String cookieval = conn.getHeaderField("set-cookie");
		      System.out.println(cookieval);
		      String sessionid=null;
		      if(cookieval != null){
		    	  sessionid=cookieval.substring(0,cookieval.indexOf(";"));
		    	  
		      }
		      System.out.println(sessionid);
		      this.session_id=sessionid+"&path=/";
		      in.close();
			
			
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return valid;
	}
	public void postURL(){
		try {
			Proxy proxy=new Proxy(java.net.Proxy.Type.HTTP,new InetSocketAddress

(this.proxyAddr,this.proxyPost));
			URL url=new URL(sub_gdly);
			HttpURLConnection conn = (HttpURLConnection)url.openConnection();

			conn.setRequestProperty("host","www.163.com");
			conn.setRequestProperty("Connection","keep-alive");
			conn.setRequestProperty("cookie", session_id.substring(0,session_id.indexOf("&")));

			sb.append

需要完善的是代理,我在网上看到都的基本是用拨号处理,不知道java做拨号程序方便不?
然后就是参数的配置文件化:比如url,post中的参数等
