如何执行POST请求并从服务器获取响应？

Question

I need to do a POST request to SERVER by such example:

REQUEST FORMAT:

POST /oauth/authorize HTTP/1.1
Host: m.sp-money.yandex.ru (для мобильных устройств) или sp-money.yandex.ru (для остальных  устройств)
Content-Type: application/x-www-form-urlencoded
Content-Length: <content-length>

client_id=<client_id>&response_type=code
&redirect_uri=<redirect_uri>&scope=<scope>

REQUEST PARAMETERS EXAMPLE:

client_id=092763469236489593523464667
response_type=code
redirect_uri=https://client.example.com/cb
scope=account-info operation-history

Now, I have been done a transfer for headers:

protected Void doInBackground(Void... arg)
        {
            List<NameValuePair> params = new ArrayList<NameValuePair>();
            params.add(new BasicNameValuePair("HOST", "sp-money.yandex.ru"));
            params.add(new BasicNameValuePair("Content-Type", "application/x-www-form-urlencoded"));
            params.add(new BasicNameValuePair("Content-Length", "154"));

            JSONObject testJSON = makeHttpRequest("https://money.yandex.ru/oauth/authorize", "POST", params);
            int test = 1;
            return null;
        }

public JSONObject makeHttpRequest(String url, String method, List<NameValuePair> params) 
        {
            try 
            {
                if(method == "POST")
                {
                    String responseText = null;
                    DefaultHttpClient httpClient = new DefaultHttpClient();
                    HttpPost httpPost = new HttpPost(url);
                    httpPost.setEntity(new UrlEncodedFormEntity(params));
                    String testStr = httpPost.toString();
                    HttpResponse httpResponse = httpClient.execute(httpPost);
                    responseText = EntityUtils.toString(httpResponse.getEntity());                
                    int test = 1;
                    test = 0;
                }          
            }
//.............................................
}

How can I do a transfer for parameters(client_id, response_type, redirect_uri, scope)? And how can I get response from server? RESPONSE EXAMPLE:

HTTP/1.1 302 Found
Location: https://client.example.com/cb?code=i1WsRn1uB1ehfbb37

In your doInBackground you can try something like this.

HttpClient client = new DefaultHttpClient();
            HttpPost post = new HttpPost(HTTP_REQUEST_URL);

            //create and assign post request server data
            String latitude = loc.getLatitude() + "";
            String longitude = loc.getLongitude() + "";
            String time = DateFormat.getDateTimeInstance().format(Calendar.getInstance().getTime()) + "";
            String whr = WhereAmI(loc.getLatitude(), loc.getLongitude());

            //data back from server
            String responseBackFromServer = "";

            try {
                List<NameValuePair> pairs = new ArrayList<NameValuePair>();

                pairs.add(new BasicNameValuePair("latitude", latitude));
                pairs.add(new BasicNameValuePair("longitude", longitude));
                pairs.add(new BasicNameValuePair("whereAmI", whr));
                pairs.add(new BasicNameValuePair("time", time));

                post.setEntity(new UrlEncodedFormEntity(pairs));
                HttpResponse server_response = client.execute(post);

                responseBackFromServer = EntityUtils.toString(server_response.getEntity());

            } catch (UnsupportedEncodingException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            } catch (Exception e) {
                e.printStackTrace();
            }

            return "Response Back: " + responseBackFromServer;

and In onPostExecute you can do whatever with the reponse.
