Question

我正在开发一个Android应用程序，它将带有用户名和密码的发布请求发送到服务器，然后我成功地获得了正确的响应。但是，当我在登录后尝试单击发送另一个帖子请求的按钮时，我从服务器收到一条消息，说我还没有登录。我知道这与存储cookie有关，有人可以帮我解决这样做？这是html客户端代码：

    public class SimpleHttpClient {

  private static HttpClient mHttpClient;


    private static HttpClient getHttpClient() {
    if (mHttpClient == null) {
        mHttpClient = new DefaultHttpClient();
        final HttpParams params = mHttpClient.getParams();
        HttpConnectionParams.setConnectionTimeout(params, HTTP_TIMEOUT);
        HttpConnectionParams.setSoTimeout(params, HTTP_TIMEOUT);
        ConnManagerParams.setTimeout(params, HTTP_TIMEOUT);
    }
    return mHttpClient;
}


public static String executeHttpPost(String url, ArrayList<NameValuePair> postParameters) throws Exception {
    BufferedReader in = null;
    try {
        HttpClient client = getHttpClient();
        HttpPost request = new HttpPost(url);
        UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(postParameters);
        request.setEntity(formEntity);
        HttpResponse response = client.execute(request);
        in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

        StringBuffer sb = new StringBuffer("");
        String line = "";
        String NL = System.getProperty("line.separator");
        while ((line = in.readLine()) != null) {
            sb.append(line + NL);
        }
        in.close();

        String result = sb.toString();
        return result;
    }
    finally {
        if (in != null) {
            try {
                in.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

我前段时间遇到过同样的问题。
您可以在CookieStore中序列化Cookie并在登录时将其保存在某处。

httpclient.execute(//login);
CookieStore cookieStore = httpclient.getCookieStore();
saveCookieData(cookieStore);

在发出帖子请求之前，请对其进行反序列化，然后将其设置为http客户端。

httpclient.setCookieStore(retrieveCookieStore());

如何保持登录/维护cookie会话？
