HttpClient4模拟登录总是失败，Cookie不工作，

Question

第一个请求是成功的，但是第二个请求总是被重定向到登录页面。我使用httpclient4.0.1。

public class HttpClientLoginTest {
    <!-- The configuration items-->
    private static String userName = "admin";
    private static String password = "12315";
    private static String redirectURL = "/manager/index.php";

    private static String LoginURL = "http://localhost/manager/login.php";

    private HttpResponse response;

    private static DefaultHttpClient httpclient = new DefaultHttpClient();
    <!-- the first request is login-->
    private void login() throws Exception {

        HttpPost httpost = new HttpPost("http://localhost/manager/login.php");
        <!--  All the parameters post to the web site-->
        List<NameValuePair> nvps = new ArrayList<NameValuePair>();
        nvps.add(new BasicNameValuePair("gotopage", redirectURL));
        nvps.add(new BasicNameValuePair("dopost", "login"));
        nvps.add(new BasicNameValuePair("adminstyle", "newdedecms"));
        nvps.add(new BasicNameValuePair("userid", userName));
        nvps.add(new BasicNameValuePair("pwd", password));
        nvps.add(new BasicNameValuePair("sm1", ""));

        httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));

        response = httpclient.execute(httpost);

        int responseCode = response.getStatusLine().getStatusCode();

        System.out.println("Sending 'POST' request to URL : " + LoginURL);
        System.out.println("Response Code : " + responseCode);
            <!-- print reponsebody-->
        BufferedReader rd = new BufferedReader(new InputStreamReader(response
                .getEntity().getContent()));

        StringBuffer result = new StringBuffer();
        String line = "";
        while ((line = rd.readLine()) != null) {
            result.append(line);
        }

        System.out.println(result.toString());

        httpost.abort();

    }
    <!-- the second request-->
    private String getText(String redirectLocation) throws Exception,
            IOException {
        HttpGet request = new HttpGet(redirectLocation);

        response = httpclient.execute(request);

        int responseCode = response.getStatusLine().getStatusCode();

        System.out.println("request to URL : " + redirectLocation);
        System.out.println("Response Code : " + responseCode);
            <!-- print reponsebody-->
        BufferedReader rd = new BufferedReader(new InputStreamReader(response
                .getEntity().getContent()));

        StringBuffer result = new StringBuffer();
        String line = "";
        while ((line = rd.readLine()) != null) {
            result.append(line);
        }

        return result.toString();
    }

    public void printText() {
        try {
            login();
            getText("http://localhost/manager/index.php");
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

    public static void main(String[] args) {
        HttpClientLoginTest test = new HttpClientLoginTest();
        test.printText();
        httpclient.getConnectionManager().shutdown();
    }

}

在这里，日志！非常感谢你！

我得到了一些情况下的annswer.in，在表单发布之前，我们需要访问的页面first.when我们访问的页面，它会给我们一个sessionid.then的表单和会话i发布到服务器together.if我们没有先访问页面，我们直接发布的表单，我们不能登录。
