应用引擎标准环境调用bigquery python

Question

我正在尝试在 python 中部署一个简单的标准应用引擎，并从那里通过 python bigquery 客户端进行 bigquery 查询。

代码就这么简单：

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)

错误日志：错误出现在虚拟查询请求中

我无法使用 python bigquery 客户端库使其工作，这是我在标准应用引擎环境中发现的工作，

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)
