java httpclient 模拟登陆开心001的问题

Question

public void login(String email,String pwd){

httpClient = new HttpClient();
httpClient.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);

String url = "http://www.kaixin001.com/login/login.php";

PostMethod postMethod = new PostMethod(url);
NameValuePair[] data = { new NameValuePair("email", email),
new NameValuePair("password", pwd),
new NameValuePair("url", "/home/") };

postMethod.setRequestBody(data);

try {
statusCode = httpClient.executeMethod(postMethod);
         if (statusCode == HttpStatus.SC_MOVED_TEMPORARILY) { Header locationHeader = postMethod.getResponseHeader("location");


postMethod.releaseConnection();
if (locationHeader != null){
String cookieUrl = locationHeader.getValue();
GetMethod getMethod = new GetMethod(cookieUrl);
                                             //就在这个地方登陆失败
httpClient.executeMethod(getMethod);
getMethod.releaseConnection();
}


} 
postMethod.releaseConnection();
} catch (Exception e) {
// System.err.println(e.getMessage());
}
}
=================================================================================
statusCode 是302 ，不过重定向时，总是出异常，有人做过吗？  是不是我的cookie没有做处理？

www.kaixin.com的我写出来了，她和www.kaixin001.com不一样

Answer 3

修正后的代码如下：
  public static void login(String email,String pwd){  HttpClient httpClient = new HttpClient(); 
                //去掉cookie设置，采用httpclient的默认cookie设置 String url = "http://www.kaixin001.com/login/login.php";  PostMethod postMethod = new PostMethod(url); 
NameValuePair[] data = { new NameValuePair("email", email), 
new NameValuePair("password", pwd), 
new NameValuePair("url", "/home/") };  postMethod.setRequestBody(data);  try { 
int statusCode = httpClient.executeMethod(postMethod); 
System.out.println("statusCode--"+statusCode);
//Cookie[] cookies=httpClient.getState().getCookies(); 
        if (statusCode == HttpStatus.SC_MOVED_TEMPORARILY) {  Header locationHeader = postMethod.getResponseHeader("location"); 
                postMethod.releaseConnection(); 
if (locationHeader != null){ 
String cookieUrl = locationHeader.getValue(); 
System.out.println("cookieUrl--"+cookieUrl);
String r_url="http://www.kaixin001.com"+cookieUrl;//修改302后的url
System.out.println("r_url--"+r_url);
GetMethod getMethod = new GetMethod(r_url); 
//httpClient.getState().addCookies(cookies);
                                           
int status=httpClient.executeMethod(getMethod); 
System.out.println("status---"+status);
System.out.println(getMethod.getResponseBodyAsString());

getMethod.releaseConnection(); 
} 
} 
postMethod.releaseConnection(); 
} catch (Exception e) { 
// System.err.println(e.getMessage()); 
} 
} 
这可是我花了半个晚上搞定的，呵呵！

Answer 4

Header locationHeader = postMethod.getResponseHeader("location"); ??我记得，在URLConnection里面，是可以后台自动重定向的，难道HttpClient不支持？还需要自己解析？
