  • Fix Google Compute Engine breakage (#411, breakage introduced in #387) that made it impossible to obtain access tokens
  • Implement ServiceAccountCredentials.from_p12_keyfile_buffer() to allow passing a file-like object in addition to the factory constructor that uses a filename directly (#413)

v2.0.0

  • Add django_util (#332)
  • Avoid OAuth2Credentials id_token going out of sync after a token refresh (#337)
  • Move to a contrib sub-package code not considered a core part of the library (#346, #353, #370, #375, #376, #382)

  • Fall back to read-only credentials on EACCES errors (#389)
  • Coalesced the two ServiceAccountCredentials classes (#395, #396, #397, #398, #400)

Special Note About ServiceAccountCredentials:

For JSON keys, you can create a credential via

from oauth2client.service_account import ServiceAccountCredentials
credentials = ServiceAccountCredentials.from_json_keyfile_name(
    key_file_name, scopes=[...])

You can still rely on

from oauth2client.client import GoogleCredentials
credentials = GoogleCredentials.get_application_default()

returning these credentials when you set the GOOGLE_APPLICATION_CREDENTIALS environment variable.

For .p12 keys, construct via

credentials = ServiceAccountCredentials.from_p12_keyfile(
    service_account_email, key_file_name, scopes=[...])

though we urge you to use JSON keys (rather than .p12 keys) if you can.

This is equivalent to the previous method

# PRE-oauth2client 2.0.0 EXAMPLE CODE!
from oauth2client.client import SignedJwtAssertionCredentials

with open(key_file_name, 'rb') as key_file:
    private_key = key_file.read()

credentials = SignedJwtAssertionCredentials(
    service_account_email, private_key, scope=[...])

    • Some calls, for example, taskqueue().lease() used to require a parameter named body. In this new release only methods that really need to send a body require a body parameter, and so you may get errors about an unknown body parameter in your call. The solution is to remove the unneeded body={} parameter.

v1.0beta7

  • Support for batch requests.
  • Support for media upload.
  • Better handling for APIs that return something other than JSON.
