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
}

I am trying to use an Interceptor to add a header when using Retrofit. I think I have created my Interceptor in the right way but I don't know what should I do to call it and connect it with my GET Retrofit method.
This is my Interceptor:
public class HeaderInterceptor
implements Interceptor {
#Override
public Response intercept(Chain chain)
throws IOException {
Request request = chain.request();
request = request.newBuilder()
.addHeader(Constants.VersionHeader.NAME, Constants.VersionHeader.VALUE)
.addHeader("Authorization", "Bearer " + token)
.addHeader("Origin","MY URL")
.build();
Response response = chain.proceed(request);
return response;
}
}
And this is my interface:
public interface CategoryService {
#GET("/v3/projects/{projectId}/categories/")
Call<ArrayList<Category2>> getProjectCategories(#Path("projectId") String projectId);
}
I also have this client which I don't know if I should use it anymore considering that I am using an Interceptor:
public class CategoryClient {
public static final String BASE_URL = "MY URL";
private static Retrofit retrofit = null;
public static Retrofit getClient() {
if (retrofit==null) {
retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();
}
return retrofit;
}
}
So I have this GET method getProjectCategories, where I pass the projectID and it returns the contents. What I want to know is how can I call the method using the Interceptor and be able to get the results from the request.
I was able to fix my problem by creating a method called SendNetworkRequest sending the projectId as a parameter, and inside this class I created my OkHttpClient, my Interceptor and my retrofit builder to handle everything that i needed.
private void SendNetworkRequest(String projectID) {
OkHttpClient.Builder okhttpBuilder = new OkHttpClient.Builder();
okhttpBuilder.addInterceptor(new Interceptor() {
#Override
public okhttp3.Response intercept(Chain chain) throws IOException {
Request request = chain.request();
Request.Builder newRequest = request.newBuilder().header("Authorization", "Bearer " + token);
return chain.proceed(newRequest.build());
}
});
Retrofit.Builder builder = new Retrofit.Builder()
.baseUrl("MY URL")
.client(okhttpBuilder.build())
.addConverterFactory(GsonConverterFactory.create());
Retrofit retrofit = builder.build();
CategoryService category = retrofit.create(CategoryService.class);
Call<ArrayList<Category2>> call = category.getProjectCategories(projectID, token);
call.enqueue(new Callback<ArrayList<Category2>>() {
#Override
public void onResponse(Call<ArrayList<Category2>> call, Response<ArrayList<Category2>> response) {
listCategories = response.body();
listCategories.remove(response.body().size() - 1);
if (response.body().size() > 0){
add_category_layout.setVisibility(View.VISIBLE);
layout_bar.setVisibility(View.VISIBLE);
message_body.setVisibility(View.INVISIBLE);
message_title.setVisibility(View.INVISIBLE);
edit_image.setVisibility(View.INVISIBLE);
adapter2 = new CategoryAdapter2(getApplicationContext(), listCategories);
recyclerView.setAdapter(adapter2);
recyclerView.setVisibility(View.VISIBLE);
}
}
#Override
public void onFailure(Call<ArrayList<Category2>> call, Throwable t) {
// Log error here since request failed
Log.e(TAG, t.toString());
}
});
}
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.

String credentials = email + ":" + password;
String basic = "Basic " + Base64.encodeToString(credentials.getBytes(),Base64.NO_WRAP);
OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
httpClient.addInterceptor(chain -> {

.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!
