アプリケーションエンジンの標準環境呼び出しbigquery python

Question

私はPythonで単純な標準のアプリケーションエンジンを配備しようとしています。そこからpython bigqueryクライアントを介してbigqueryクエリを作成しようとしています。

コードは、これらのように簡単です：

from __future__ import absolute_import 
import webapp2 
import os 
from google.cloud import bigquery 

class MainPage(webapp2.RequestHandler): 
    def get(self): 


    client = bigquery.Client(project = "ancient-ceiling-125223") 
    project_name = str(client.project) 

    query_job = client.query("select 1") 

    assert query_job.state == 'RUNNING' 

    iterator = query_job.result(timeout= 30) 

    rows = list(iterator) 

    self.response.write('nothing to see %s' % (project_name)) 


app = webapp2.WSGIApplication(
[('/', MainPage)], debug=True) 

エラーログ：エラーがダミーのクエリ要求

に表示されます私はそれがクライアントライブラリのBigQueryのpythonを使用して動作させることができませんでした、標準のアプリエンジン環境で働いていたことがわかりました。

from __future__ import absolute_import 
import webapp2 

from googleapiclient.discovery import build 
from oauth2client.client import GoogleCredentials 


class MainPage(webapp2.RequestHandler): 
    def get(self): 

    credentials = GoogleCredentials.get_application_default() 
    service = build('bigquery', 'v2', credentials=credentials) 

    datasets = service.datasets().list(projectId="ancient-ceiling-125223").execute() 

    self.response.write('datasets: %s' % datasets) 


app = webapp2.WSGIApplication(
    [('/', MainPage)], debug=True)
