旧版本DefaultHttpClient 使用getCookieStore可以直接获取cookies信息，但apache升级4.5后，DefaultHttpClient过期了，可以使用CloseableHttpClient做为替换获取cookies，代码如下：

//存储cookies信息变量
CookieStore store = new BasicCookieStore();
//设置cookies信息
CloseableHttpClient client = HttpClients.custom().setDefaultCookieStore(store).build();
 HttpResponse response = client.execute(get);
        result = EntityUtils.toString(response.getEntity(), "utf-8");
        System.out.println(result);

        //获取cookies信息
        List<Cookie> cookieList = store.getCookies();

        for (Cookie cookie:cookieList) {
            String name = cookie.getName();
            String value = cookie.getValue();
            System.out.println("cookie name = " + name
                    + ";  cookie value = " + value);
        }
