登录后的JAVA HttpClient 401

我精通java和web编程。但我必须为android编写应用程序，它可以与http一起工作。 我为http请求编写了类，但有一个问题：当我发送另一个请求时，授权后出现错误401。 它可以是什么？我怎样才能修理它？ 谢谢你的帮助

public void SendRequest(final String url)  {
        Thread t = new Thread(new Runnable() {
            @Override
            public void run() {

                URI website = null;
                try {
                    website = new URI(baseUri+url);
                } catch (URISyntaxException e) {
                    e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
                }
                HttpGet request = new HttpGet();
                request.setURI(website);
                HttpResponse response = null;
                try {
                    response = client.execute(request, localContext);
                } catch (IOException e) {
                    e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
                }
                if (response != null)
                {
                    HttpEntity entity = response.getEntity();
                    try {
                        InputStream is = entity.getContent();
                        httpEvent.HttpResponseArrived(convertStreamToString(is),response.getStatusLine().getStatusCode());
                    } catch (IOException e) {
                        e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
                    }
                }
            }
        });
        t.start();
    }

public void Login(String login, String password, boolean isRemember)
    {
        String mess = "logon?username="+login+"&password="+password+"&remember="+ Boolean.toString(isRemember);

            SendRequest(mess);
            httpEvent = new HttpHandler()
            {
                @Override
                public void HttpResponseArrived(String data, int code)
                {
                    String mess = "Error";
                    switch (code)
                    {
                        case 401:
                            mess = "Incorrect login/password";
                            break;
                        case 200:
                            mess = "";
                            break;
                    }
                    events.LoginArrived(Boolean.valueOf(data), mess);
                }
            };
    }

您是否发送了会话id以便服务器识别您？I jast发送了登录名和密码：）当您登录到某个对象时，会在服务器上保存一个会话以记住您。cookie可能会被发回，您应该在以后的请求中使用它。我尝试过类似的方法，但它不起作用：CookieStore CookieStore=new BasicCookieStore（）；HttpContext HttpContext=新的BasicHttpContext（）；setAttribute（ClientContext.COOKIE_存储，cookieStore）；你有没有问过自己这些代码行是做什么的？这些有什么帮助吗？
