I am developing login and register using the external database from a youtube tutorial that uses HttpClient, HttpParams, HttpPost, HttpResponse and HttpEntity. However, these functions are deprecated. Please help to modify the below code using HttpUrlConnection.
public class ServerRequests {
ProgressDialog progressDialog;
public static final int CONNECTION_TIMEOUT = 1000 * 15;
public static final String SERVER_ADDRESS = "http://classpark.16mb.com/";
public ServerRequests(Context context){
progressDialog = new ProgressDialog(context);
progressDialog.setCancelable(false);
progressDialog.setTitle("Processing");
progressDialog.setMessage("Please wait...");
}
public void storeUserDataInBackground(User user, GetUserCallback userCallback){
progressDialog.show();
new StoreUserDataAsyncTask(user, userCallback).execute();
}
public void fetchUserDataInBackground(User user, GetUserCallback callback){
progressDialog.show();
new fetchUserDataAsyncTask(user,callback).execute();
}
public class StoreUserDataAsyncTask extends AsyncTask<Void,Void,Void> {
User user;
GetUserCallback userCallback;
public StoreUserDataAsyncTask(User user, GetUserCallback userCallback){
this.user = user;
this.userCallback = userCallback;
}
@Override
protected Void doInBackground(Void... Params){
ArrayList<NameValuePair> dataToSend = new ArrayList<>();
dataToSend.add(new BasicNameValuePair("name", user.name));
dataToSend.add(new BasicNameValuePair("email", user.email));
dataToSend.add(new BasicNameValuePair("username", user.username));
dataToSend.add(new BasicNameValuePair("password", user.password));
HttpParams httpRequestParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpRequestParams, CONNECTION_TIMEOUT);
HttpConnectionParams.setSoTimeout(httpRequestParams, CONNECTION_TIMEOUT);
HttpClient client = new DefaultHttpClient(httpRequestParams);
HttpPost post = new HttpPost(SERVER_ADDRESS + "Register.php");
try {
post.setEntity(new UrlEncodedFormEntity(dataToSend));
client.execute(post);
}catch (Exception e){
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Void aVoid){
progressDialog.dismiss();
userCallback.done(null);
super.onPostExecute(aVoid);
}
}
public class fetchUserDataAsyncTask extends AsyncTask<Void,Void,User> {
User user;
GetUserCallback userCallback;
public fetchUserDataAsyncTask(User user, GetUserCallback userCallback){
this.user = user;
this.userCallback = userCallback;
}
@Override
protected User doInBackground(Void... params){
ArrayList<NameValuePair> dataToSend = new ArrayList<>();
dataToSend.add(new BasicNameValuePair("username", user.username));
dataToSend.add(new BasicNameValuePair("password", user.password));
HttpParams httpRequestParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpRequestParams, CONNECTION_TIMEOUT);
HttpConnectionParams.setSoTimeout(httpRequestParams, CONNECTION_TIMEOUT);
HttpClient client = new DefaultHttpClient(httpRequestParams);
HttpPost post = new HttpPost(SERVER_ADDRESS + "FetchUserData.php");
User returnedUser = null;
try {
post.setEntity(new UrlEncodedFormEntity(dataToSend));
HttpResponse httpResponse = client.execute(post);
HttpEntity entity = httpResponse.getEntity();
String result = EntityUtils.toString(entity);
JSONObject j0bject = new JSONObject(result);
if (j0bject.length() == 0){
returnedUser = null;
}else {
String name = j0bject.getString("name");
String email = j0bject.getString("email");
returnedUser = new User(name, email,user.username, user.password);
}
}catch (Exception e){
e.printStackTrace();
}
return returnedUser;
}
@Override
protected void onPostExecute(User returnedUser){
progressDialog.dismiss();
userCallback.done(returnedUser);
super.onPostExecute(returnedUser);
}
}
}
