java使用POST请求模拟登录openstack horizon问题请教

我目前写了一段HttpClient模仿浏览器发送POST请求来登录openstack horizon的代码，目的是自己写一个登录页面来替代掉horizon本身的登录页面来实现登录，POST请求/dashboard/auth/login/，参数和csrftoken均能取到，大概代码如下：

        CloseableHttpClient client = HttpClientBuilder.create().build();

        URI uri = null;



        Kv kv = getCookiesStr();

        System.out.println("kv is :"+kv.toString());



        List<NameValuePair> params = new ArrayList<>();

        params.add(new BasicNameValuePair("username","admin"));

        params.add(new BasicNameValuePair("password","123456"));

        params.add(new BasicNameValuePair("region","http://10.0.11.211:5000/v3"));

        params.add(new BasicNameValuePair("csrfmiddlewaretoken",kv.getStr("csrfmiddlewaretoken")));

        params.add(new BasicNameValuePair("fake_email",""));

        params.add(new BasicNameValuePair("fake_password",""));

        params.add(new BasicNameValuePair("next","/dashboard/"));



        uri = new URIBuilder().setScheme("http").setHost("10.0.11.71").setPort(80)

                .setPath("/dashboard/auth/login/").setParameters(params).build();

        HttpPost post = new HttpPost(uri);





        String csrftoken = kv.getStr("csrftoken").split("=")[1];

        post.setHeader("X-CSRFToken",csrftoken);

        post.setHeader("Cookie",kv.getStr("csrftoken"));

        post.setHeader("User-Agent","Mozilla/5.0 (X11; Linux x86_64; rv:66.0) Gecko/20100101 Firefox/66.0");

        post.setHeader("Host","10.0.11.71");

        post.setHeader("Origin","10.0.11.71");

        post.setHeader("Pragma","10.0.11.71");

        post.setHeader("Cache-Control","no-cache");

        post.setHeader("Connection","keep-alive");

        post.setHeader("Upgrade-Insecure-Requests","1");

        post.setHeader("Content-Type","application/x-www-form-urlencoded");

        post.setHeader("Referer","http://10.0.11.71/dashboard/auth/login/?next=/dashboard/");

        post.setHeader("Accept-Encoding","gzip, deflate");

        post.setHeader("Accept-Language","zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2");

        post.setHeader("Accept","text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");



        CloseableHttpResponse response = client.execute(post);

        System.out.println("status+++:"+response.getStatusLine());

        System.out.println("respone body+++:"+EntityUtils.toString(response.getEntity()));

        System.out.println("respone header++:"+response.getAllHeaders());

        for(Header header:response.getAllHeaders()){

            System.out.println("header==>:"+header.getName()+":"+header.getValue());

        }

        System.out.println("status:++++++"+response.getStatusLine());

返回的response信息如下：

看response body是直接给我返回到horizon自己的登录界面了，而且返回的header里没有sessionid，login_region也是空的，和正常浏览器请求登录返回的状态码302也不同，而keystone和apache2的日志里也没有任何报错日志，不知道哪位大佬试过用post来模拟登录openstack的horizon，情不吝赐教帮助我一下！感谢！
