Question

private static HttpClient client = new DefaultHttpClient(); static void login(String txtID,String txtPW) throws IOException {
static void login(String txtID,String txtPW) throws IOException {
// HttpPost post = new HttpPost("http://www.yojj.com");
  HttpGet get1 =  new HttpGet("http://www.yojj.com/login_code.aspx?1");
  HttpResponse res = client.execute(get1);
  File f = new File("d:\\test454ss5.bmp");
  OutputStream ops = new FileOutputStream(f);
  res.getEntity().writeTo(ops);
String imgStr = new GetIbcbetImg().getImg(f);
         ops.close();
  String pw = MD5Util.MD5(txtPW+imgStr);
         EntityUtils.consume(res.getEntity());
HttpGet get =  new HttpGet("http://www.yojj.com/ProcessLogin.aspx?"
+"selLang=en&txtID="+txtID+"&txtPW="+pw+"&txtCode="
+imgStr+"&hidKey=&hidLowerCasePW=&hidServerKey=ibcbet.com");
get.setHeader("Host", "www.yojj.com");
get.setHeader("User-Agent",
"Mozilla/5.0 (Windows NT 6.1) AppleWebKit/536.11 (KHTML, like Gecko) Chrome/20.0.1132.57 Safari/536.11");
get.setHeader("Accept",

get.setHeader("Connection", "keep-alive");
get.setHeader("Referer", "http://www.yojj.com/");
//HttpResponse response = client.execute(get);
System.out.println(res.getStatusLine().getStatusCode());
res = client.execute(get);
HttpEntity entity = res.getEntity();
String result = dumpRes(entity);
if(result.indexOf("www.yojj.com:80/rulesalert.aspx") > 0){
HttpGet get4 = new HttpGet("http://www.yojj.com/rulesalert.aspx?Accept=YES");
HttpResponse response4 = client.execute(get4);
HttpEntity entity4 = response4.getEntity();
System.out.println(response4.getStatusLine().getStatusCode());
System.out.println(EntityUtils.toString(entity4, "UTF-8"));

HttpGet get6 = new HttpGet("http://ytojh.yojj.com/");
HttpResponse response6 = client.execute(get6);
       int statusCode6 = response6.getStatusLine().getStatusCode();


String url = "http://ytojh.yojj.com/ValidateTicket.aspx?c=%2fQGFDRdYp0k%3d&t=1745925191&l=en&f=nReSaj6pl4g%3d&o=16GPeAjqfVU5kfIPYgw1Tg%3d%3d";
HttpGet get5 = new HttpGet(url);
HttpResponse response5 = client.execute(get5);//地址变了这里错误
       int statusCode = response5.getStatusLine().getStatusCode();//网上都说这里302的时候重定向但是我上面一行就错了还没到这里 }

}
这个怎么做啊 可以加分啊

你有福气了，这应该是个Bug：
https://issues.apache.org/jira/browse/HTTPCLIENT-1193
一个可能的临时解决方案是使用SingleClientConnManager或者PoolingClientConnectionManager，类似于：
ClientConnectionManager connManager = new PoolingClientConnectionManager();
DefaultHttpClient httpclient = new DefaultHttpClient(connManager);

Answer 3

HttpGet get6 = new HttpGet("http://ytojh.yojj.com/");
HttpResponse response6 = client.execute(get6);
这里网址换了，client不要用原来的了，再创建一个，用新的。HttpClient client1 = new DefaultHttpClient();
client1.execute(get6);
或者private static HttpClient client = new DefaultHttpClient();
DefaultHttpClient换成PoolingConnectionManager
