今天做的一个简单投票程序

an_six

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urlString sub_gdly="http://";//投票处理的urlString 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 blocke.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.setDoOutput(true);conn.setRequestMethod("POST");conn.setRequestProperty("User-Agent","Mozilla/4.0 (compatible; MSIE 6.0; Windows 2000)");conn.setRequestProperty("host","www.163.com");conn.setRequestProperty("Connection","keep-alive");conn.setRequestProperty("cookie", session_id.substring(0,session_id.indexOf("&")));StringBuffer sb=new StringBuffer();sb.append("name=01&name=10&name=02&name=03&name=04&name=05&name=06&name=24&name=07&name=08&name1=hhhf&sex=%C4%D0&tele=111111111&comp=111111&addr=11111&postcode=010000&verifycode=" +this.id+"&B1=%CC%E1%BD%BB");System.out.println(sb.toString());OutputStream os=conn.getOutputStream();os.write(sb.toString().getBytes("GBK"));os.close();BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));conn.connect();String line = br.readLine();while(line != null){System.out.println(line);line = br.readLine();}} catch (MalformedURLException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}public static void main(String args[]){for(int i=0;i<10;i++){shuapiao u=new shuapiao("http://");u.id=u.getUrl();u.postURL();}}}
