Is there a way to use Simple Access API (Developer Key) instead of oAuth2 key with Google Cloud Endpoint?
回答1:
Extra fields in your protorpc request object that aren't part of the definition are still stored with the request.
If you wanted to use a key field as a query parameter, you could access it via
request.get_unrecognized_field_info('key')
even if key is not a field in your message definition.
This is done in users_id_token.py (the Auth part of the endpoints library) to allow sending bearer_token or access_token as query parameters instead of as header values.
Unfortunately, the nice quota checking and other associated pieces that a "Simple API Access" key gives are not readily available. However, you could issue your own keys and manually check a key against your list and potentially check against quotas that you have defined.

P.S. I tried to make this a comment in @bossylobster's answer, but I don't have the reputation to do that. Feel free to clean up this answer so that other's can follow the path
