Python+；BigQuery+；ResponseNotReady（）

我正在使用“bigquery_service=build（'bigquery'，'v2'，http=http）”，它在我的笔记本电脑中正确执行，但当我在服务器上执行此查询时，我得到以下错误

File "/usr/lib64/python2.6/threading.py", line 532, in __bootstrap_inner
    self.run()
  File "/usr/lib64/python2.6/threading.py", line 484, in run

    raise ResponseNotReady()

http = httplib2.Http()
http = credentials.authorize(http)
service = build('bigquery', 'v2', http=http)

您是否尝试删除“http=http”参数

http = httplib2.Http()
http = credentials.authorize(http)
service = build('bigquery', 'v2', http=http)

以下是使用BQ API的示例：

import httplib2

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

# REPLACE WITH YOUR Project ID
PROJECT_NUMBER = 'XXXXXXXXXXX'
# REPLACE WITH THE SERVICE ACCOUNT EMAIL FROM GOOGLE DEV CONSOLE
SERVICE_ACCOUNT_EMAIL = 'XXXXX@developer.gserviceaccount.com'

# OBTAIN THE KEY FROM THE GOOGLE APIs CONSOLE
# More instructions here: http://goo.gl/w0YA0
f = file('key.p12', 'rb')
key = f.read()
f.close()

credentials = SignedJwtAssertionCredentials(
    SERVICE_ACCOUNT_EMAIL,
    key,
    scope='https://www.googleapis.com/auth/bigquery')

http = httplib2.Http()
http = credentials.authorize(http)

service = build('bigquery', 'v2')
datasets = service.datasets()
response = datasets.list(projectId=PROJECT_NUMBER).execute(http)

print 'Dataset list:'
for dataset in response['datasets']:
  print '%s' % dataset['datasetReference']['datasetId']

http = httplib2.Http()
http = credentials.authorize(http)
service = build('bigquery', 'v2', http=http)

你可以试试。它是围绕Google BigQuery API的一个薄薄的包装

http = httplib2.Http()
http = credentials.authorize(http)
service = build('bigquery', 'v2', http=http)

要登录到BigQuery：

import bigquery as bq

with open('my_key.pem', 'r') as key:
    key_content = key.read()

bq_client = bq.get_client(project_id='foo',
                          service_account='bar',
                          private_key=key_content)

http = httplib2.Http()
http = credentials.authorize(http)
service = build('bigquery', 'v2', http=http)

要提交加载作业，请执行以下操作：

schema = [{'name':'foo', 'type':'STRING'}]
job = bq_client.import_data_from_uris(source_uris=['gs://foo/bar'],
                                        dataset='foo',
                                        table='bar',
                                        schema=schema,
                                        source_format=bq.client.JOB_FORMAT_CSV,
                                        write_disposition=bq.client.JOB_WRITE_TRUNCATE,
                                        field_delimiter=',',
                                        skip_leading_rows=1)


try:
    job_resource = bq_client.wait_for_job(job, timeout=60)        
except bq.errors.BigQueryTimeoutException:
    logging.critical('BigQuery loading timeout.')

http = httplib2.Http()
http = credentials.authorize(http)
service = build('bigquery', 'v2', http=http)

通过为运行此操作的服务器指定代理服务器主机和端口，解决了此问题。在凭据的帮助下启动授权http服务对象时，我对代码进行了如下修改：

http = httplib2.Http()
http = credentials.authorize(http)
service = build('bigquery', 'v2', http=http)

之前：

http = httplib2.Http()
http = credentials.authorize(http)
service = build('bigquery', 'v2', http=http)

修正：

http = httplib2.Http()
http = credentials.authorize(http)
service = build('bigquery', 'v2', http=http)
