Cannot access HTTP headers from Cloud Endpoints Python

Question

I'm implementing custom authentication in Google Cloud Endpoints for an Android app. To do so, I'm sending an auth token in an HTTP header. From Android:

private static final String HEADER_AUTH_TOKEN = "HTTP_AUTHORIZATION";

private GoogleClientRequestInitializer requestInitializer =
    new GoogleClientRequestInitializer() {

   @Override
   public void initialize(AbstractGoogleClientRequest<?> request) throws IOException {
      HttpHeaders headers = request.getRequestHeaders();
      if (authPrefs.authToken().exists()) {
          headers.set(HEADER_AUTH_TOKEN, authPrefs.authToken().get().toString());
      }
      request.setRequestHeaders(headers);
   }
};

Api.Builder apiBuilder = new Api.Builder(
    AndroidHttp.newCompatibleTransport(),
    new GsonFactory(),
    null);

return apiBuilder.setApplicationName(APPLICATION_NAME)
         .setGoogleClientRequestInitializer(requestInitializer)
         .build()

Then in Python I'm trying to retrieve the auth token header:

import os
auth_token = os.getenv('HTTP_AUTHORIZATION')

auth_token is None. What am I missing?

It turns out "HTTP_" was being prepended to any HTTP header sent. HTTP_AUTHORIZATION was being sent as "HTTP_HTTP_AUTHORIZATION".
