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 createMM         


        

Answer 1

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();
