Retrofit - Intercept responses globally

Question

I\'d like to intercept all responses received by the retrofit engine, and scan for HTTP error code, for example error 403.

I\'m aware I can use the failure(RetrofitE

Another possibility is to override the execute method in Retrofit's OkClient. In my case I was looking for a specific response header, so it went something like this:

OkClient client = new OkClient(okHttpClient) {
    @Override
    public retrofit.client.Response execute(retrofit.client.Request request) throws IOException {
        retrofit.client.Response response = super.execute(request);

        // Do whatever with 'response', such as looking for the value of a particular header:

        List headers = response.getHeaders();
        for (retrofit.client.Header header : headers) {
            if (MY_HEADER.equalsIgnoreCase(header.getName())) {
                this.savedValue = header.getValue();
                break;
            }
        }

        return response;
    }
};

RestAdapter.Builder restAdapterBuilder = new RestAdapter.Builder()
        .setEndpoint(API_BASE_URL)
        .setClient(client);
