Handling Authentication in Okhttp

Question

I'm using OkHttp 2.3 with basic authentication requests, according to OKHttp docs, it automatically retries unauthenticated requests, but whenever I provide invalid credentials, the request takes too much time and I get this exception in the end:

java.net.ProtocolException: Too many follow-up requests: 21

How can I prevent OkHttp from automatically retrying unauthenticated requests, and return 401 Unauthorized instead?

Answer 1

protected Authenticator getBasicAuth(final String username, final String password) {
    return new Authenticator() {
        private int mCounter = 0;

        @Override
        public Request authenticate(Proxy proxy, Response response) throws IOException {
            if (mCounter++ > 0) {
                throw new AuthenticationException(
                        AuthenticationException.Type.INVALID_LOGIN, response.message());
            }

            String credential = Credentials.basic(username, password);
            return response.request().newBuilder().header("Authorization", credential).build();
        }

        @Override
        public Request authenticateProxy(Proxy proxy, Response response) throws IOException {
            return null;
        }
    };
}

In my Authenticator I simply count the tries - after X tries, I throw an exception.
