AttributeError: 'module' object has no attribute 'SignedJwtAssertionCredentials'

Problem: I've been using Python Script Samples by Google to upload the apk to Play Store and to get list of apps published via my account (list_apks.py and upload_apk.py). However recently it started breaking. I've tried to update the packages like google-api-python-client, oath2client etc by doing pip install --update packagename but it didn't help.

Logs:

This if while listing apk's:

This is when uploading apk:

Code sniplet:

import argparse

from apiclient.discovery import build
import httplib2
from oauth2client import client


SERVICE_ACCOUNT_EMAIL = (
    'myaccountemail.com')

# Declare command-line flags.
argparser = argparse.ArgumentParser(add_help=False)
argparser.add_argument('package_name',
                       help='The package name. Example: com.android.sample')


def main():
  # Load the key in PKCS 12 format that you downloaded from the Google APIs
  # Console when you created your Service account.
  f = file('mykeyname.p12', 'rb')
  key = f.read()
  f.close()

  # HERE IS THE EXCEPTION 
  credentials = client.SignedJwtAssertionCredentials(
      SERVICE_ACCOUNT_EMAIL,
      key,
      scope='https://www.googleapis.com/auth/androidpublisher')
  http = httplib2.Http()
  http = credentials.authorize(http)
  ...

What else I can try? I would appreciate your help.

Solution

  • Finally after so many days, I was able to find answer to it. It turns out that the class SignedJwtAssertionCredentials was removed from the oath2client python package in the 2.0.0 update. It was no more under oauth2client.client. The behaviour has been moved onto oauth2client.service_account.ServiceAccountCredentials.

    Following worked for me:

    import argparse

from apiclient.discovery import build
from oauth2client.service_account import ServiceAccountCredentials

import httplib2
from oauth2client import client

SERVICE_ACCOUNT_EMAIL = ('myaccountemail.com')

# Declare command-line flags.
argparser = argparse.ArgumentParser(add_help=False)
argparser.add_argument('package_name',
                   help='The package name. Example: com.android.sample')

def main():
  key='mykeyname.p12'
  scope = 'https://www.googleapis.com/auth/androidpublisher'

  credentials = ServiceAccountCredentials.from_p12_keyfile(
      SERVICE_ACCOUNT_EMAIL,
      key,
      scopes=[scope]
  )
  http = httplib2.Http()
  http = credentials.authorize(http)
  ....
