Android send data over HTTP and receive body response

Question

I saw that the version of Android API 22 DefaultHttpClient is deprecated. In my old code I had to send data to a PHP page and get the response that the page php returned. By using this code:

HttpClient client = new DefaultHttpClient(); HttpPost request = new HttpPost("php page"); ArrayList<NameValuePair> parameters = new ArrayList<NameValuePair>(); parameters.add(new BasicNameValuePair("username", "user")); parameters.add(new BasicNameValuePair("password", "pw")); HttpResponse response = client.execute(request); String responseMessage = response.getEntity().toString();

I saw that NameValuePair is deprecated. My question is how can I do the same thing in another way not deprecated. As I said I need to send data (via post) to a php page and get what page PhP printing. (In my case a string JSON). Many thanks in advance!!.

No thanks. The last months many others posted the same problem. So if you google a bit you find many answers on this site. — greenapps

Ma no grazie cosa?... che ti venissero le emorroidi al culo sfigato. Piuttosto che dare una risposta del genere potevi spararti una sega. — federicostudio96

Use HttpURLConnection. Set you values as JSONObject instead of setting it as NameValuePair.

public HttpURLConnection createConnection(){ try{ urlconnection=(HttpURLConnection)url.openConnection(); }catch(Exception e){ Log.e("Can't create connections", e.getMessage()); } return urlconnection; } public String doFunctionPost(JSONObject object){ try{ urlconnection=createConnection(); urlconnection.setDoInput(true); urlconnection.setDoOutput(true); urlconnection.setRequestMethod(method); urlconnection.setUseCaches(false); urlconnection.setConnectTimeout(10000); urlconnection.setReadTimeout(10000); urlconnection.setRequestProperty("json", object.toString()); urlconnection.setRequestProperty("Content-Type", "application/json"); OutputStreamWriter out=new OutputStreamWriter(urlconnection.getOutputStream()); out.write(object.toString()); System.out.println(object.toString()); out.close(); httpResult=urlconnection.getResponseCode(); System.out.println("Response Code"+ httpResult); result=readResponse(); }catch(Exception e){ Log.e("Response Error", e.getMessage()); }finally{ removeConnection(); } return result; } public String readResponse(){ try{ if(httpResult==HttpURLConnection.HTTP_OK){ BufferedReader buffer_reader=new BufferedReader(new InputStreamReader(urlconnection.getInputStream(),"utf-8")); String line=null; sb=new StringBuilder(); while((line=buffer_reader.readLine())!=null){ sb.append(line+"\n"); } buffer_reader.close(); System.out.println("buffer_reader"+sb.toString()); }else{ Log.e("Error on posting", urlconnection.getResponseMessage()); } }catch(Exception e){ Log.e("Error in Response", e.getMessage()); } return sb.toString(); }
