httpClient 3如何session会话保持？

Question

问题场景：
通过httpClient请求同一门户的接口地址，因为登录后和未登录的时候返回的数据不一样。所以当用户在门户上登录的情况下，访问接口返回的数据也应该是要登录口的数据。现在返回的都是未登录的情况。‘请问大神们此问题如何解决。

代码如下：

String url = "http://192.168.41.56/portal/480/home/wap/xqy/ljjk/dbjqbf/index.jsp";
String result = "";

    HttpClient client = new HttpClient(); 
    //client.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);
    HttpConnectionManagerParams managerParams = client.getHttpConnectionManager().getParams(); 
    // 设置连接超时时间(单位毫秒) 
    managerParams.setConnectionTimeout(500);
    managerParams.setSoTimeout(5000); 
    GetMethod getMethod=new GetMethod();
    URI base = new URI(url,false);     
    getMethod.setURI(new URI(base,"",false));
    int resultCode = client.executeMethod(getMethod);
    if(resultCode == 200 ) {    
        byte[] body=getMethod.getResponseBody();
        if(body!=null && body.length>0){
            result=new String(body,"UTF-8");
            System.out.println(result);
        }else{
            System.out.println(" 无返回值  url ="+url);
        }
    }else{
        System.out.println(" HTTP 返回异常 url ="+url +", resultCode= "+ resultCode);
    }
    getMethod.releaseConnection();
