Retrofit and OkHttp basic authentication

Question

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?

Answer 1

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();
