Retrofit2 authorization

Question

There is an HTTP client:

 public class App extends Application { public static MessengerApi service; private static OkHttpClient client; private static Retrofit retrofit; @Override public void onCreate() { super.onCreate(); HttpLoggingInterceptor logger = new HttpLoggingInterceptor(); logger.setLevel(HttpLoggingInterceptor.Level.BODY); client = new OkHttpClient.Builder() .connectTimeout(60, TimeUnit.SECONDS) .readTimeout(30, TimeUnit.SECONDS) .addInterceptor(logger) .build(); retrofit = new Retrofit.Builder() .baseUrl(BuildConfig.BASE_URL) .client(client) .addConverterFactory(GsonConverterFactory.create()) .addCallAdapterFactory(RxJavaCallAdapterFactory.create()) .build(); service = retrofit.create(MessengerApi.class); } }

And this interface:

 public interface MessengerApi { @GET("users") Observable<User> users(); }

I need to add authorization (username, password) now. How to do it? A little confused in the tutorials.

If you show us the description of the function, it will be much easier to help you

first, what is your authorization?

if basic, then use as an example

 "Basic " + Base64.encodeToString((username + ":" + password).getBytes("UTF-8"), Base64.NO_WRAP)

and

 @GET("users") Observable<User> users(@Header("Authorization") String auth);

And how to understand the use of basic authorization or not basic?
This line "Basic" + Base64.encodeToString ((username + ":" + password) .getBytes ("UTF-8"), Base64.NO_WRAP) "is the String auth?
en.wikipedia.org/wiki/Basic_access_authentication , a "" Basic "+ Base64.encodeToString ((username +": "+ password) .getBytes (" UTF-8 "), Base64.NO_WRAP)" in auth you shove.

Create an object for login / password

 public class RequestLogin { private String username; private String password; public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } }

Then pass it as a parameter to the service function.

 public interface MessengerApi { @GET("login") Observable<User> login(RequestLogin login); }

And use so

 RequestLogin login = new RequestLogin(); login.setUsername("moylogin"); login.getPassword("moy-parol"); call = messengerApi.login(login);

If you still use get, then something like this

 @GET("users") Observable<User> users(@Query("username") String username,@Query("password") String password);

Then the answer is better to wrap the class:

 class UserResponse { private List<User> user; } class User { private String username; private String name; private String email; private int properties; }

Retrofit function will be such

 @GET("users") Observable<UserResponse> login(@Query("username") String username, @Query("password") String password);

Regarding @Query ("username") username - issues Annotations are not allowed here, Cannot resolve symbol "username"
