a digest authenticator for okhttp

okhttp-digest

A digest authenticator for okhttp. Most of the code is ported from Apache Http Client.

Usage

        client = new OkHttpClient();
        final DigestAuthenticator authenticator = new DigestAuthenticator(new Credentials("username", "pass"));

        final Map<String, CachingAuthenticator> authCache = new ConcurrentHashMap<>();
        client.interceptors().add(new AuthenticationCacheInterceptor(authCache));
        client.setAuthenticator(new CachingAuthenticatorDecorator(authenticator, authCache));

        Request request = new Request.Builder()
          .url(url);
          .get()
          .build();
        Response response = client.newCall(request).execute();

If you want to support multiple authentication schemes (including auth caching) then this should work:

            OkHttpClient.Builder builder = new OkHttpClient.Builder();
            final Map<String, CachingAuthenticator> authCache = new ConcurrentHashMap<>();

            Credentials credentials = new Credentials("username", "pass");
            final BasicAuthenticator basicAuthenticator = new BasicAuthenticator(credentials);
            final DigestAuthenticator digestAuthenticator = new DigestAuthenticator(credentials);

            // note that all auth schemes should be registered as lowercase!
            DispatchingAuthenticator authenticator = new DispatchingAuthenticator.Builder()
                    .with("digest", digestAuthenticator)
                    .with("basic", basicAuthenticator)
                    .build();

            client = builder
                    .authenticator(new CachingAuthenticatorDecorator(authenticator, authCache))
                    .addInterceptor(new AuthenticationCacheInterceptor(authCache))
                    .addNetworkInterceptor(logger)
                    .build();
