Java HttpClient未保持登录状态

我尝试在使用HttpClient登录后浏览网站

我首先定义一个HttpClient实例和一个cookie存储：

public HttpClient httpclient = new DefaultHttpClient();
public CookieStore cookieStore = new BasicCookieStore();
public HttpContext localContext = new BasicHttpContext();
localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);

在一个（android）背景任务中，我成功登录了该网站

HttpPost httppost = new HttpPost("http://www.deeproute.com/deeproute/default.asp");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("cookieexists","false"));
nameValuePairs.add(new BasicNameValuePair("name", mUser));
nameValuePairs.add(new BasicNameValuePair("password", mPassword));
nameValuePairs.add(new BasicNameValuePair("subbera", "Login"));

httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
res = httpclient.execute(httppost, localContext);

但是，当我连接到此页面时，我将不再登录。我看了一下，成功登录后的cookies仍然在，所以我不知所措

编辑：作为记录，本网站在普通浏览器中完全正常运行

编辑2:根据Aaron下面的回答，cookies似乎正在保存，因为如果在第一次请求后，我会这样做：

List<Cookie> cookies = cookieStore.getCookies();
    int cookieSize = cookies.size();

    for (int i = 0; i < cookieSize; i++) {
        Log.v(TAG, "Cookie " + i + "name: "
                                + cookies.get(i).getName());
        Log.v(TAG, "Cookie " + i + "value: "
                                + cookies.get(i).getValue());
    }

在第二个请求之后，我有两个会话ID cookie：

name: ASPSESSIONIDSCSCSBCS
value: GBAJALJBOGKBFLAELPNKEDOE

name: ASPSESSIONIDSCSCSBCS
value: MBAJALJBDBOKPEHNCDDFOCBC

看起来不像您在初始请求中保存的cookies，因此在下一个请求中没有任何内容可以告诉站点您已登录。

你需要一个饼干容器。谷歌搜索。我遇到了同样的问题。我实现了cookies，但是它仍然没有保持登录状态。我终于让它工作了，所以我发布这段代码希望能帮助其他人解决同样的问题

以下是Apache中关于如何登录和检索所有cookie的示例：

您还可以在此处查看Apache关于“HTTP状态管理”的HttpClient文档：

以下是我的登录功能的实现方式：

使用

CredentialsProvider设置代理

使用

BasicCookieStore

使用

CloseableHttpClient

设置后请求：目标、主机、参数、路径

执行向

/login.html

发送请求以登录

执行对

/user

的GET请求，查看我们是否正确登录

打印响应的状态代码

谢谢你的回答，但是我认为cookie正在保存，因为如果我打印cookie列表的元素，我确实看到了值。我还在谷歌上搜索了cookie容器，但我唯一能找到的是CookieManager，它似乎只适用于Android网络视图？
