I have followed the instructions in https://developers.google.com/bigquery/authorization#service-accounts-appengine to make some queries from app engine to bigquery.
In the step 2, I click on Team in Google Api Console and it redirects to App Engine > Administration > Permissions. I add the service account name as Email and as a role I select developer (the option "can edit" is not available), and then click "Invite user". After that, appears a message: "An email was sent to [email protected] for verification." and the status is Pending. How I could confirm the email?, seems there is a bug here...
Next, I made a test using the following code:
#!/usr/bin/env python
import httplib2
import webapp2
from google.appengine.api import memcache
from apiclient.discovery import build
from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app
from oauth2client.appengine import AppAssertionCredentials
# BigQuery API Settings
PROJECT_NUMBER = 'XXXXXXXX'
credentials = AppAssertionCredentials(scope='https://www.googleapis.com/auth/bigquery')
http = credentials.authorize(httplib2.Http(memcache))
service = build("bigquery", "v2", http=http)
class MainHandler(webapp2.RequestHandler):
def get(self):
query = {'query':'SELECT word,count(word) AS count FROM publicdata:samples.shakespeare GROUP BY word;',
'timeoutMs':10000}
jobRunner = service.jobs()
reply = jobRunner.query(projectId=PROJECT_NUMBER,body=query).execute()
self.response.out.write(reply)
app = webapp2.WSGIApplication([
('/', MainHandler)
], debug=True)
And the reply was (running from google):
HttpError: <HttpError 403 when requesting https://www.googleapis.com/bigquery/v2/projects/XXXXXXXX/queries?alt=json returned "Access Denied: Job YYYYYYYY:job_e57bdde0144c495dbc864ccbfb82b704: RUN_QUERY_JOB">
If I test from localhost, the answer is:
HttpError: <HttpError 401 when requesting https://www.googleapis.com/bigquery/v2/projects/XXXXXXXX/queries?alt=json returned "Invalid Credentials">
Someone could help me? :-)
