How to get token from wordpress-rest-api using Retrofit Android?

How to get token from wordpress-rest-api using Retrofit Android? - java

I’m developing Android app that’s based on a WordPress website, so I need to get a token to login the user to the app using the JWT method.
When I send a request, I don’t get any response from the server; probably there something wrong with my code. I installed the wordpress-rest-api plugin and jwt-auth-plugin on the website.
My code contains userModel.java which contains getters and setters for the user id, email, and token.
retroFitInterface.java:
#POST ("Authorization: Bearer")
Call<User> login (#Body Login login);
#GET ("secretinfo")
Call<ResponseBody>getSecret(#Header("Authorization")String authToken);
Login.java:
private String email,password;
public Login (String email,String password) {
this.email = email;
this.password = password;
}
}
MainActivity.java
Retrofit.Builder builder = new Retrofit.Builder().baseUrl("https://taqoh.com/wp-json/jwt-auth/v1/token").addConverterFactory(GsonConverterFactory.create());
Retrofit retrofit = builder.build();
RetroFitInterface retroFitInterface = retrofit.create(RetroFitInterface.class);
private Button button, button1;
private static String token;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = findViewById(R.id.login_btn);
button1 = findViewById(R.id.get_token_btn);
}
private void login() {
Login login = new Login("isohunter1#hotmail.com", "qweqweqwe123");
Call<User>call = retroFitInterface.login(login);
call.enqueue(new Callback<User>() {
#Override
public void onResponse(Call<User> call, Response<User> response) {
if (response.isSuccessful()) {
Toast.makeText(MainActivity.this, response.body().getEmail(), Toast.LENGTH_LONG).show();
token = response.body().getToken();
}
}
#Override
public void onFailure(Call<User> call, Throwable t) {
Toast.makeText(MainActivity.this, "error", Toast.LENGTH_LONG).show();
}
});
}
private void getSecret() {
Call<ResponseBody>secret = retroFitInterface.getSecret(token);
secret.enqueue(new Callback<ResponseBody>() {
#Override
public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
}
#Override
public void onFailure(Call<ResponseBody> call, Throwable t) {
}
});
}
#Override
public void onClick(View v) {
if (v.getId() == R.id.login_btn) {
login();
} else if (v.getId() == R.id.get_token_btn) {
getSecret();
}
}

How do I execute two methods using onClickListener?

I'm new to android studio and I'm trying to create a simple weather app using OpenWeatherMap API. I am using OkHttp library to perform a GET request. All it does is take an input throught EditText and update the TextView on button click using a Button.
But the problem is, the TextView updates after two clicks on the Button. I want to update it right after the first click. So, how do I go over this?
Here is my code:
public class MainActivity extends AppCompatActivity {
private EditText cityName;
private TextView weatherData;
private TextView hiddenText;
private Button getBtn;
public String s = "";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
weatherData = (TextView)findViewById(R.id.weatherText);
getBtn = (Button)findViewById(R.id.getData);
cityName = (EditText)findViewById(R.id.cityName);
getBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
getWeatherData(cityName.getText().toString());
weatherData.setText(s);
}
});
}
public void getWeatherData(String cityText){
String url = "https://api.openweathermap.org/data/2.5/weather?q=" + cityText + "&appid=ba45ceb57328448f7wd666hdc6d57aaf";
OkHttpClient client = new OkHttpClient();
final Request request = new Request.Builder().url(url).build();
client.newCall(request).enqueue(new Callback() {
#Override
public void onFailure(Call call, IOException e) {
MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
s = "Something went wrong!";
}
});
}
#Override
public void onResponse(Call call, final Response response) throws IOException {
if(response.isSuccessful()){
MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
try{
s = response.body().string();
}
catch (IOException ioe){
s = "Error while getting JSON.";
}
}
});
}
}
});
}
}
I know that I can update the TextView in onResponse itself but I wanna know if it is possible to update it through onClickListener. If it's not possible, which method should I use? Any help would be appreciated.

you have to update text value in server response call back
public class MainActivity extends AppCompatActivity {
private EditText cityName;
private TextView weatherData;
private TextView hiddenText;
private Button getBtn;
public String s = "";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
weatherData = (TextView)findViewById(R.id.weatherText);
getBtn = (Button)findViewById(R.id.getData);
cityName = (EditText)findViewById(R.id.cityName);
getBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
getWeatherData(cityName.getText().toString());
}
});
}
public void getWeatherData(String cityText){
String url = "https://api.openweathermap.org/data/2.5/weather?q=" + cityText + "&appid=ba45ceb57328448f7wd666hdc6d57aaf";
OkHttpClient client = new OkHttpClient();
final Request request = new Request.Builder().url(url).build();
client.newCall(request).enqueue(new Callback() {
#Override
public void onFailure(Call call, IOException e) {
MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
s = "Something went wrong!";
}
});
}
#Override
public void onResponse(Call call, final Response response) throws IOException {
if(response.isSuccessful()){
MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
try{
s = response.body().string();
weatherData.setText(s);
}
catch (IOException ioe){
s = "Error while getting JSON.";
}
}
});
}
}
});
}
}

You are setting data on edit text on click after calling GET Request.
Update the textview with the data , once you get the response.
public class MainActivity extends AppCompatActivity {
private EditText cityName;
private TextView weatherData;
private TextView hiddenText;
private Button getBtn;
public String s = "";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
weatherData = (TextView)findViewById(R.id.weatherText);
getBtn = (Button)findViewById(R.id.getData);
cityName = (EditText)findViewById(R.id.cityName);
getBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
getWeatherData(cityName.getText().toString());
}
});
}
public void getWeatherData(String cityText){
String url = "https://api.openweathermap.org/data/2.5/weather?q=" + cityText + "&appid=ba45ceb57328448f7wd666hdc6d57aaf";
OkHttpClient client = new OkHttpClient();
final Request request = new Request.Builder().url(url).build();
client.newCall(request).enqueue(new Callback() {
#Override
public void onFailure(Call call, IOException e) {
MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
s = "Something went wrong!";
}
});
}
#Override
public void onResponse(Call call, final Response response) throws IOException {
if(response.isSuccessful()){
MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
try{
s = response.body().string();
weatherData.setText(s);
}
catch (IOException ioe){
s = "Error while getting JSON.";
}
}
});
}
}
});
}
}

Please, help me)

You need to override the ToString() method in this class using the IDE or by typing it your self as now you are accessing the object allocation id and not the object values.

Retrofit, TimeoutException

I'm using retrofit authentication, and I have a timeoutexception. I saw many questions, but I can't solve this.
Here's the code

I have no error in retrofit, I'm doing debugging and I see all the process, so I getting client id and secret successfully, then I'm getting a timeoutexception in the last onfailure(),
#Override
public void onFailure(Call<ResponseBody> call, Throwable t)
{
Toast.makeText(getContext(), "You're onfailure",Toast.LENGTH_SHORT).show();
}
watch the code, that's the last line. How to fix it? The app not crashes, but in debug he drops timeoutexception like this. t={SocketTimeoutException#830038722120}java.net.SocketTimeoutException: timeout . In OkHttpClient the
readTimeout(10, TimeUnit.SECONDS).connectTimeout(10, TimeUnit.SECONDS).writeTimeout(10, TimeUnit.SECONDS); all are 10, i tried to set it 100, not helps. Help me. Thanks.

Correct code location to check Firebase if a user has been created already?

I've created a method to take a users facebook data, after they login, and create a "user" for them on my firebase database. this method, addUser(), also creates and sets the variables for said user. But I have to leave the method in, login, so it creates my variables, then comment the method out for future testing, or it will reset all the values.
So where can I add "addUser()" to create said user the first time, and make sure it never call it again, as long as the user already exists?

You need to set a preference like FIRST_LAUNCH and check if its true each time your user logs in. First time the application launches, the FIRST_LAUNCH preference won't be found. So call your addUser() function to create a new entry in your FireBase database.
SharedPreferences pref = getSharedPreferences(Constants.ApplicationTag, Activity.MODE_PRIVATE);
if (!pref.contains(Constants.FIRST_LAUNCH)) {
addUser();
pref.edit().putBoolean(Constants.FIRST_LAUNCH, true).commit();
}
So you might be thinking of if an user uninstalls your application and then reinstalls it, the preferences will be gone and the addUser() function will be called again. No problem, you won't get a new Firebase entry as long as the path to the child attribute is the same. The values will be replaced to the specific path (if it does exist), with current information of user.
Now if you want to check if your user already exists in Firebase database you need to add a listener like this. I'm attaching a code sample for better understanding.
Firebase rootRef = new Firebase("https://<url>.firebaseio.com/users/");
Firebase userRef = rootRef.child(mAuthData.getUid() + "/");
userRef.addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
if (dataSnapshot.exists()) {
// User exists. Do nothing
} else addUser();
}
#Override
public void onCancelled(FirebaseError firebaseError) {}
});

Android Facebook SDK 4.X , how to get Email address and Facebook Access Token to pass it to Web Service

EDIT :
My Question is how to get Email , UserId , Facebook Authentication with Facebook SDK 4.X , at this moment , with Ming Respond , i know how can i get Email , User Id , so my question is how to get Facebook Authentication since Session and GraphUser has just been replaced by LoginManager and AccessToken and there is no information about it?

Easiest answer that i found after hours of searching is as follows,the highest voted answer didn't work for me and email was alway empty
LoginManager.getInstance().registerCallback(mCallbackManager,
new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
GraphRequest request = GraphRequest.newMeRequest(AccessToken.getCurrentAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(JSONObject object,GraphResponse response) {
JSONObject json = response.getJSONObject();
try {
if(json != null){
String text = json.getString("email");
Log.d("email",text);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,link,email,picture");
request.setParameters(parameters);
request.executeAsync();
}
#Override
public void onCancel() {
// App code
}
#Override
public void onError(FacebookException exception) {
// App code
}
});
I believe setting parameters as required fields to the Graph Request is a crucial thing here. You can also use this code with LoginButton, works without issue.
****** Update********
After using this code with many accounts found that if the email isn't verified it won't be returned, in such case following code helped along with abo
facebookLoginButton.setReadPermissions("email");
Hope this helps further

I must add extra field for user Email.
//register facebook login callback
LoginManager.getInstance().registerCallback(mCallbackManager, new FacebookCallback<LoginResult>()
{
#Override
public void onSuccess (LoginResult loginResult)
{
Log.d(TAG, "FB: login success");
showLoading(true);
final String token = loginResult.getAccessToken().getToken();
//prepare fields with email
String[] requiredFields = new String[]{"email"};
Bundle parameters = new Bundle();
parameters.putString("fields", TextUtils.join(",", requiredFields));
GraphRequest requestEmail = new GraphRequest(loginResult.getAccessToken(), "me", parameters, null, new GraphRequest.Callback()
{
#Override
public void onCompleted (GraphResponse response)
{
if (response != null)
{
GraphRequest.GraphJSONObjectCallback callbackEmail = new GraphRequest.GraphJSONObjectCallback()
{
#Override
public void onCompleted (JSONObject me, GraphResponse response)
{
if (response.getError() != null)
{
Log.d(TAG, "FB: cannot parse email");
showDialog(getString(R.string.dialog_message_unknown_error));
showLoading(false);
}
else
{
String email = me.optString("email");
// send email and id to your web server
//...
}
}
};
callbackEmail.onCompleted(response.getJSONObject(), response);
}
}
});
requestEmail.executeAsync();
}
#Override
public void onCancel ()
{
Log.d(TAG, "FB: login cancel");
showDialog(getString(R.string.dialog_message_unknown_error));
}
#Override
public void onError (FacebookException e)
{
Log.d(TAG, "FB: login error " + e.getMessage());
showDialog(getString(R.string.dialog_message_unknown_error));
}
});
