This includes `OAuth error handling`_ and `Client authentication for OAuth flows`_. OAuth error handling -------------------- This will define interfaces for handling OAuth related error responses as stated in `RFC 6749 section 5.2`_. This will include a common function to convert these HTTP error responses to a :class:`google.auth.exceptions.OAuthError` exception. Client authentication for OAuth flows ------------------------------------- We introduce an interface for defining client authentication credentials based on `RFC 6749 section 2.3.1`_. This will expose the following capabilities: * Ability to support basic authentication via request header. * Ability to support bearer token authentication via request header. * Ability to support client ID / secret authentication via request body. .. _RFC 6749 section 2.3.1: https://tools.ietf.org/html/rfc6749#section-2.3.1 .. _RFC 6749 section 5.2: https://tools.ietf.org/html/rfc6749#section-5.2 N) exceptionsceZdZdZdZy)ClientAuthTypeN)__name__ __module__ __qualname__basic request_bodyH/var/www/openai/venv/lib/python3.12/site-packages/google/oauth2/utils.pyrr5s ELrrceZdZdZddZy)ClientAuthenticationzDefines the client authentication credentials for basic and request-body types based on https://tools.ietf.org/html/rfc6749#section-2.3.1.
