登录到Url并获取个人资料数据并对网站进行更多操作

Question

假设有一个网站没有提供api服务。但是，合法的Android应用程序想要提供有用的服务。首先，他们要求用户在该网站上创建一个帐户。然后，一旦用户登录，他们就能够从应用程序中执行某些功能，例如“喜欢”帖子或评论内容。但很明显，CSRF令牌用于所有表单提交。 Android应用程序是否能够获取此令牌？如果没有，是否有办法要求用户获取权限

那么如何在android中执行此过程有任何一个答案？

这是我的代码我所做的，但我无法弄清楚当我们发出HttpPost请求时它说没有正确使用csrf令牌/ Csrf令牌......

    void sendGet() throws Exception {

    String url = "http://manch.net.in/adda/accounts/login/";
    String sessionId = "";
    String key="";
    URL obj = new URL(url);
    HttpURLConnection con = (HttpURLConnection) obj.openConnection();
    String cs = CookieManager.getInstance().getCookie("http://manch.net.in/adda/accounts/login/");
    DefaultHttpClient httpclient = new DefaultHttpClient();

    httpclient.execute(new HttpGet(url));
    CookieStore cookieStore = httpclient.getCookieStore();
    List <Cookie> cookies =  cookieStore.getCookies();

    System.out.println("cookieeeee"+cookies);
    for (Cookie cookie: cookies) {
        if (cookie.getName().equals("csrftoken")) {
            CSRFTOKEN = cookie.getValue();
            System.out.println("cccc"+CSRFTOKEN);
        }
        if (cookie.getName().equals("sessionid")) {
            String session = cookie.getValue();
            System.out.println("session"+session);
        }


    }
    MunchWebViewClientDemoActivity d=new MunchWebViewClientDemoActivity();
    int responseCode = con.getResponseCode();
    System.out.println("\nSending 'GET' request to URL : " + url);
    System.out.println("Response Code : " + responseCode);
    BufferedReader in = new BufferedReader(
            new InputStreamReader(con.getInputStream()));
    String inputLine;
    StringBuffer response = new StringBuffer();
    while ((inputLine = in.readLine()) != null) {
        response.append(inputLine);
    }
    in.close();
    }

// HTTP POST request
void sendPost() throws Exception {

try {
        HttpClient client = new DefaultHttpClient();  
        String postURL = "http://manch.net.in/adda/get_my_activity/";
        HttpPost post = new HttpPost(postURL);
            //post.addHeader("csrftoken", CSRFTOKEN);
            List<NameValuePair> params = new ArrayList<NameValuePair>();
            params.add(new BasicNameValuePair("username", "abhishekkeshri"));
            params.add(new BasicNameValuePair("password", "1234"));
            params.add(new BasicNameValuePair("csrftoken",CSRFTOKEN ));

            UrlEncodedFormEntity ent = new UrlEncodedFormEntity(params,HTTP.UTF_8);
            post.setEntity(ent);
            HttpResponse responsePOST = client.execute(post);  
            HttpEntity resEntity = responsePOST.getEntity();
             System.out.println("ressss"+resEntity.toString());
            if (resEntity != null) {    
                Log.i("RESPONSE",EntityUtils.toString(resEntity));
            }
    } catch (Exception e) {
        e.printStackTrace();
         }
         }      

提前知道。
