Before Android API 22 i simply did the following:
/**
*
* @param url
* @param params
* @return
* @throws ClientProtocolException
* @throws IOException
*/
public InputStream getStreamFromConnection(String url, List<NameValuePair> params) throws ClientProtocolException, IOException {
if(ConnectionDetector.isConnectedToInternet(this.context)) {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params, "utf-8"));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
return httpEntity.getContent();
} else {
return null;
}
}
Nearly everything in the above code now is deprecated (NameValuePair
, DefaultHttpClient
, HttpPost
, UrlEncodedFormEntity
, HttpResponse
, HttpEntity
, ClientProtocolException
) and i cant find a recommend way to do in API 22+. How should i do my post now?
You can use HttpURLConnection now, you can find complete description at below link:
http://developer.android.com/reference/java/net/HttpURLConnection.html
this is an example for async task with POST method:
private class SendMessageTask extends AsyncTask<String, Void, String> {
Graduate targetGraduate;
public SendMessageTask(Graduate targetGraduate){
this.targetGraduate = targetGraduate;
}
@Override
protected String doInBackground(String... params) {
URL myUrl = null;
HttpURLConnection conn = null;
String response = "";
String data = params[0];
try {
myUrl = new URL("http://your url");
conn = (HttpURLConnection) myUrl.openConnection();
conn.setReadTimeout(10000);
conn.setConnectTimeout(15000);
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);
//one long string, first encode is the key to get the data on your web
//page, second encode is the value, keep concatenating key and value.
//theres another ways which easier then this long string in case you are
//posting a lot of info, look it up.
String postData = URLEncoder.encode("TOKEN", "UTF-8") + "=" +
URLEncoder.encode(targetGraduate.getToken(), "UTF-8") + "&" +
URLEncoder.encode("SENDER_ID", "UTF-8") + "=" +
URLEncoder.encode(MainActivity.curretUser.getId(), "UTF-8") + "&" +
URLEncoder.encode("MESSAGE_DATA", "UTF-8") + "=" +
URLEncoder.encode(data, "UTF-8");
OutputStream os = conn.getOutputStream();
BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(os, "UTF-8"));
bufferedWriter.write(postData);
bufferedWriter.flush();
bufferedWriter.close();
InputStream inputStream = conn.getInputStream();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"));
String line = "";
while ((line = bufferedReader.readLine()) != null) {
response += line;
}
bufferedReader.close();
inputStream.close();
conn.disconnect();
os.close();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return response;
}
@Override
protected void onPostExecute(String s) {
//do what ever you want with the response
Log.d("roee", s);
}
}
