Retrofit Logging Error

I am authenticating against an API EndPoint using the Password Grant Flow for OAuth2. The library I am using is Retrofit.
I get the following error:
D/OkHttp: {"error":"invalid_clientId","error_description":"ClientId should be sent."}
I would like to see exactly what API Call I am sending so I can check it for errors.. I have searched the web and found that you need to add a LoggingInterceptor, which I am doing. Still not getting the full API Call..
In my log I get a track of the headers I am sending, as well as the URL, but not the body parameters.. Is there a way to also get the body parameters in the logging?
I would like to see each parameter with its sent value..
The code with provisional credentials can be found at:
https://github.com/NVwingh84/ATTAPITest
Code that I am using is:
public class MainActivity extends AppCompatActivity {
private String grant_type = "password";
private String username = "xxxxx";
private String password = "xxxxx";
private String clientId = "xxxxx";
private String client_secret = "xxxxx";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
AccessTokenRequest mytokenrequest = new AccessTokenRequest(grant_type,username,password,clientId,client_secret);
sendNetworkRequest(mytokenrequest);
}
public void sendNetworkRequest(AccessTokenRequest accessTokenRequest){
//create okhttpclientbuilder and set up logging for full logging level "Body"
OkHttpClient.Builder okhttpclientbuilder = new OkHttpClient.Builder();
HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
//App will only log if you are in development mode
if (BuildConfig.DEBUG){
okhttpclientbuilder.addInterceptor(loggingInterceptor);
}
Retrofit.Builder builder = new Retrofit.Builder()
.baseUrl("https://api.allthingstalk.io")
.addConverterFactory(GsonConverterFactory.create())
.client(okhttpclientbuilder.build());
Retrofit retrofit = builder.build();
AccessTokenClient client = retrofit.create(AccessTokenClient.class);
Call<AccessTokenRequest> call = client.getAccessToken();
call.enqueue(new Callback() {
#Override
public void onResponse(Call call, Response response) {
Toast.makeText(MainActivity.this, "EndPoint Response", Toast.LENGTH_SHORT).show();
}
#Override
public void onFailure(Call call, Throwable t) {
Toast.makeText(MainActivity.this, "Something went wrong", Toast.LENGTH_SHORT).show();
}
});
};
}

Try this code.
add below dependency into app level gradle file..
implementation 'com.squareup.okhttp3:logging-interceptor:3.4.1'
and make separate class for retrofit object define and it is easy to access like below code..
public class ApiClient {
private final static String BASE_URL = "https://dog.ceo/api/breed/";
public static ApiClient apiClient;
private Retrofit retrofit = null;
public static ApiClient getInstance() {
if (apiClient == null) {
apiClient = new ApiClient();
}
return apiClient;
}
//private static Retrofit storeRetrofit = null;
public Retrofit getClient() {
return getClient(null);
}
private Retrofit getClient(final Context context) {
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient.Builder client = new OkHttpClient.Builder();
client.readTimeout(60, TimeUnit.SECONDS);
client.writeTimeout(60, TimeUnit.SECONDS);
client.connectTimeout(60, TimeUnit.SECONDS);
client.addInterceptor(interceptor);
client.addInterceptor(new Interceptor() {
#Override
public okhttp3.Response intercept(Chain chain) throws IOException {
Request request = chain.request();
return chain.proceed(request);
}
});
retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.client(client.build())
.addConverterFactory(GsonConverterFactory.create())
.build();
return retrofit;
}
}

Retrofit json data passing

Below are the files for retrofit.
While passing the data in the form of JSON I am getting a null response.
Could anyone guide where can be the issue occurring?
I am trying to post the data in the form of JSON using the retrofit library. Can you suggest me the right approach?
My code:
public class ApiSellarClient {
public static final String BASE_URL = "Constant.BASE_URL";// it is from constant file..
private static Retrofit retrofit = null;
public static Retrofit getClient() {
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();
if (retrofit == null) {
retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.client(client)
.addConverterFactory(ScalarsConverterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.build();
}
return retrofit;
}
}
public class ApiSellarConnection {
public static Call<String> getSignInData(JSONObject json) {
return ApiSellarClient.getClient().create(ApiSellarInterface.class).getSignInData(json);
}
}
public interface ApiSellarInterface {
#Headers("Content-Type: application/json")
#POST("integration/customer/token")
Call<String> getSignInData(#Body JSONObject json);
}
// Below is the controller class.
JSONObject paramObject = new JSONObject();
try {
paramObject.put("username", etUserName.getText().toString());
paramObject.put("password", etPassword.getText().toString());
ApiSellarConnection.getSignInData(paramObject).enqueue(new Callback<String>() {
#Override
public void onResponse(Call<String> call, Response<String> response) {
Log.d("tag", "helper" + response.body());
}
#Override
public void onFailure(Call<String> call, Throwable t) {
}
});
} catch (JSONException e) {
e.printStackTrace();
}

Retrofit and OkHttp basic authentication

I am trying to add basic authentication (username and password) to a Retrofit OkHttp client. This is the code I have so far:
private static Retrofit createMMSATService(String baseUrl, String user, String pass) {
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(baseUrl)
.client(client)
.addConverterFactory(GsonConverterFactory.create())
.build();
return retrofit;
}
I am using Retrofit 2.2 and this tutorial suggests using AuthenticationInterceptor, but this class is not available.
Where is the correct place to add the credentials? Do I have to add them to my interceptor, client or Retrofit object? And how do I do that?

Find the Solution
1.Write a Interceptor class
import java.io.IOException;
import okhttp3.Credentials;
import okhttp3.Interceptor;
import okhttp3.Request;
import okhttp3.Response;
public class BasicAuthInterceptor implements Interceptor {
private String credentials;
public BasicAuthInterceptor(String user, String password) {
this.credentials = Credentials.basic(user, password);
}
#Override
public Response intercept(Chain chain) throws IOException {
Request request = chain.request();
Request authenticatedRequest = request.newBuilder()
.header("Authorization", credentials).build();
return chain.proceed(authenticatedRequest);
}
}
2.Finally, add the interceptor to an OkHttp client
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(new BasicAuthInterceptor(username, password))
.build();

Retrofit 2
public class ServiceGenerator {
public static final String API_BASE_URL = "https://your.api-base.url";
private static OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
private static Retrofit.Builder builder =
new Retrofit.Builder()
.baseUrl(API_BASE_URL)
.addConverterFactory(GsonConverterFactory.create());
private static Retrofit retrofit = builder.build();
public static <S> S createService(Class<S> serviceClass) {
return createService(serviceClass, null, null);
}
public static <S> S createService(
Class<S> serviceClass, String username, String password) {
if (!TextUtils.isEmpty(username)
&& !TextUtils.isEmpty(password)) {
String authToken = Credentials.basic(username, password);
return createService(serviceClass, authToken);
}
return createService(serviceClass, null);
}
public static <S> S createService(
Class<S> serviceClass, final String authToken) {
if (!TextUtils.isEmpty(authToken)) {
AuthenticationInterceptor interceptor =
new AuthenticationInterceptor(authToken);
if (!httpClient.interceptors().contains(interceptor)) {
httpClient.addInterceptor(interceptor);
builder.client(httpClient.build());
retrofit = builder.build();
}
}
return retrofit.create(serviceClass);
}
}
Retrofit 1.9
public class ServiceGenerator {
public static final String API_BASE_URL = "https://your.api-base.url";
private static RestAdapter.Builder builder = new RestAdapter.Builder()
.setEndpoint(API_BASE_URL)
.setClient(new OkClient(new OkHttpClient()));
public static <S> S createService(Class<S> serviceClass) {
return createService(serviceClass, null, null);
}
public static <S> S createService(Class<S> serviceClass, String username, String password) {
if (username != null && password != null) {
// concatenate username and password with colon for authentication
String credentials = username + ":" + password;
// create Base64 encodet string
final String basic =
"Basic " + Base64.encodeToString(credentials.getBytes(), Base64.NO_WRAP);
builder.setRequestInterceptor(new RequestInterceptor() {
#Override
public void intercept(RequestFacade request) {
request.addHeader("Authorization", basic);
request.addHeader("Accept", "application/json");
}
});
}
RestAdapter adapter = builder.build();
return adapter.create(serviceClass);
}
}
AuthenticationInterceptor.java
public class AuthenticationInterceptor implements Interceptor {
private String authToken;
public AuthenticationInterceptor(String token) {
this.authToken = token;
}
#Override
public Response intercept(Chain chain) throws IOException {
Request original = chain.request();
Request.Builder builder = original.newBuilder()
.header("Authorization", authToken);
Request request = builder.build();
return chain.proceed(request);
}
}

add header interceptor
public class HeaderInterceptor implements Interceptor {
private PreferencesRepository mPrefs;
private String mAuth;
public HeaderInterceptor(PreferencesRepository p) {
mPrefs = p;
}
#Override
public Response intercept(Chain chain) throws IOException {
mAuth = (mPrefs.getAuthToken() != null)?mPrefs.getAuthToken():"";
Request r = chain.request()
.newBuilder()
.addHeader("Accept", "application/json")
// authorization token here
.addHeader("Authorization", "Bearer" + mAuth)
.build();
return chain.proceed(r);
}
}
add cacheinterceptor (optional)
public class CacheInterceptor implements Interceptor {
Context mContext;
public CacheInterceptor(Context context) {
this.mContext = context;
}
#Override
public Response intercept(Chain chain) throws IOException {
Request request = chain.request();
if (request.method().equals("GET")) {
if (DeviceUtils.isConnected(mContext)) {
request = request.newBuilder()
.header(Constant.CACHE_CONTROL, "only-if-cached")
.build();
} else {
request = request.newBuilder()
.header(Constant.CACHE_CONTROL, "public, max-stale=2419200")
.build();
}
}
Response originalResponse = chain.proceed(request);
return originalResponse.newBuilder()
.header(Constant.CACHE_CONTROL, "max-age=600")
.build();
}
}
implement it
HttpLoggingInterceptor logger = new HttpLoggingInterceptor();
logger.setLevel(HttpLoggingInterceptor.Level.BODY);
long SIZE_OF_CACHE = 10 * 1024 * 1024; // 10 MiB
Cache cache = new Cache(new File(mContext.getCacheDir(), "http"), SIZE_OF_CACHE);
new OkHttpClient.Builder()
.addInterceptor(logger)
.addInterceptor(new HeaderInterceptor(u))
.cache(cache)
.addNetworkInterceptor(new CacheInterceptor(mContext))
.connectTimeout(Constant.CONNECTTIMEOUT, TimeUnit.SECONDS)
.readTimeout(Constant.READTIMEOUT, TimeUnit.SECONDS)
.writeTimeout(Constant.WRITETIMEOUT, TimeUnit.SECONDS)
.build();

Of course using auth interceptor is correct way (as explained in other answers). Although, if you need basic authentication only for single call, then auth header can be added directly in Retrofit request:
import okhttp3.Credentials
// Create credentials
val login = "some login"
val password = "some password"
// Below code will create correct Base64 encoded Basic Auth credentials
val credentials = Credentials.basic(login, password)
// Then in your Retrofit API interface
interface MyApi {
#POST("get_user")
fun getUser(#Header("Authorization") credentials: String): ResponseBody
}

HTTPS not working with OkHttp3 and Retrofit2

Well, I'm having problems to connect with my https URL, all works with postman, but I can´t do it with my Android App, Can someone help me?
Image of code.
public class NetworkUtil{
public static RetrofitInterface getRetrofit(){
return new Retrofit.Builder()
.baseUrl(Constants.BASE_URL)
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.build().create(RetrofitInterface.class);
}
public static RetrofitInterface getRetrofit(String email, String password) {
String credentials = email + ":" + password;
String basic = "Basic " + Base64.encodeToString(credentials.getBytes(),Base64.NO_WRAP);
OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
httpClient.addInterceptor(chain -> {
Request original = chain.request();
Request.Builder builder = original.newBuilder()
.addHeader("Authorization", basic)
.method(original.method(),original.body());
return chain.proceed(builder.build());
});
return new Retrofit.Builder()
.baseUrl(Constants.BASE_URL)
.client(httpClient.build())
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.build().create(RetrofitInterface.class);
}
I need to authenticate the tokens, how can i add that to the okhttp?
public static RetrofitInterface getRetrofit(String token) {
OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
httpClient.addInterceptor(chain -> {
Request original = chain.request();
Request.Builder builder = original.newBuilder()
.addHeader("x-access-token", token)
.method(original.method(),original.body());
return chain.proceed(builder.build());
});
return new Retrofit.Builder()
.baseUrl(Constants.BASE_URL)
.client(okHttpClient)
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.build().create(RetrofitInterface.class);
}
}
Thanks in advance!

Sometimes Retrofit 2.1.0 callback is not working

Callback is not working on some screens sometimes while many times it's working perfectly. I have almost done project with this library. So kindly help
My ApiClient code is:
