public static String excutePost(String targetURL, String urlParameters) { URL url; HttpURLConnection connection = null; try { //Create connection url = new URL(targetURL); connection = (HttpURLConnection)url.openConnection(); connection.setRequestMethod("POST"); connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); connection.setRequestProperty("Content-Length", "" + Integer.toString(urlParameters.getBytes().length)); connection.setRequestProperty("Content-Language", "en-US"); connection.setUseCaches (false); connection.setDoInput(true); connection.setDoOutput(true); //Send request DataOutputStream wr = new DataOutputStream ( connection.getOutputStream ()); wr.writeBytes (urlParameters); wr.flush (); wr.close (); //Get Response InputStream is = connection.getInputStream(); BufferedReader rd = new BufferedReader(new InputStreamReader(is)); String line; StringBuffer response = new StringBuffer(); while((line = rd.readLine()) != null) { response.append(line); response.append('\r'); } rd.close(); return response.toString(); } catch (Exception e) { e.printStackTrace(); return null; } finally { if(connection != null) { connection.disconnect(); } } } ... The urlParameters is a URL encoded string. String urlParameters = "fName=" + URLEncoder.encode("???", "UTF-8") + "&lName=" + URLEncoder.encode("???", "UTF-8")
