Question

我使用python从GA API获取数据。这是我的代码：

    # -*- coding: utf-8 -*-
"""Hello Analytics Reporting API V4."""

import argparse
import pandas as pd
import time

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

import httplib2

from oauth2client import file
from oauth2client import tools
from pandas import Series, DataFrame
from multiprocessing import Pool
from functools import partial


SCOPES = ['https://www.googleapis.com/auth/analytics.readonly']

KEY_FILE_LOCATION = '/Users/mac/Documents/python-f/client_secrets.p12'
SERVICE_ACCOUNT_EMAIL = 'mac-test3@prime-imagery-150409.iam.gserviceaccount.com'
VIEW_ID = '108573919'
FILE_NAME = '/Users/mac/Documents/python-f/12ios_bbs_user.csv'
DATE_RANGE = pd.date_range('1/1/2016','12/11/2016')
FILTERS = 'ga:screenName=~论坛'
SEGMENTS_ID = 'gaid::gKXoOymDSxKWjmKVPpPsbA'


def initialize_analyticsreporting():
  """Initializes an analyticsreporting service object.

  Returns:
    analytics an authorized analyticsreporting service object.
  """

  credentials = ServiceAccountCredentials.from_p12_keyfile(
    SERVICE_ACCOUNT_EMAIL, KEY_FILE_LOCATION, scopes=SCOPES)

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

  # Build the service object.
  analytics = build('analytics', 'v4', http=http, discoveryServiceUrl=DISCOVERY_URI)

  return analytics


def get_report(q_date):
  # Use the Analytics Service Object to query the Analytics Reporting API V4.
  analytics = initialize_analyticsreporting()
  return analytics.reports().batchGet(
      body={
        'reportRequests': [
        {
          'viewId': VIEW_ID,
          'dateRanges': [{'startDate': q_date, 'endDate': q_date}],
          'metrics': [{'expression': 'ga:screenviews'},{'expression': 'ga:users'}],
          'dimensions': [{'name': 'ga:date'},{'name': 'ga:segment'}],

def print_response(response):
  content=[]
  for report in response.get('reports', []):
    columnHeader = report.get('columnHeader', {})
    dimensionHeaders = columnHeader.get('dimensions', [])
    metricHeaders = columnHeader.get('metricHeader', {}).get('metricHeaderEntries', [])
    rows = report.get('data', {}).get('rows', [])
    hed_r = []
    con_r = []

    mer_h = []
    for m in metricHeaders:
      mer_h.append(m.get('name'))

    hed_r = dimensionHeaders + mer_h

    con_r.append(hed_r)

    for row in rows:
      dimensions = row.get('dimensions', [])
      dateRangeValues = row.get('metrics', [])
      line=[]
      for di in dimensions:
        line.append(di)
      for values in dateRangeValues:
        for value in values.get('values'):
          line.append(value)
      con_r.append(line)
    content.append(con_r)
  df = DataFrame(content[0])
  df.columns = df.ix[0]

  return df[1:]


def main():

 #analytics1 = initialize_analyticsreporting()
 #startTime = time.time()
  results = []
  date_range = []

  for t in DATE_RANGE:
    date_range.append(t.strftime('%Y-%m-%d'))

  pool = Pool()
  rrr=pool.map(get_report, date_range)
  pool.close()
  pool.join()

  for rlt in rrr:
    rlt = print_response(rlt)
    results.append(rlt)

  results = pd.concat(results, ignore_index=True)
 #endTime = time.time()
  results.to_csv(FILE_NAME,encoding='utf-8')




  '''
  for i, t in enumerate(DATE_RANGE):
    rlt = get_report(analytics, t.strftime('%Y-%m-%d'))
    rlt_r = print_response(rlt)
    if i==0:
      results = rlt_r
    else:
      results = pd.concat([results, rlt_r])

    results.index = range(len(results))
    results.to_csv(FILE_NAME,encoding='utf-8')
'''

if __name__ == '__main__':
  main()

我第一次破坏它，它成功了。但第二次，有一些错误，看起来像是多线程。错误讯息：

Exception in thread Thread-3:
Traceback (most recent call last):
  File "/Users/mac/.edm/envs/edm/lib/python2.7/threading.py", line 801, in __bootstrap_inner
    self.run()

    self.__target(*self.__args, **self.__kwargs)

    task = get()
  File "build/bdist.macosx-10.6-x86_64/egg/oauth2client/_helpers.py", line 133, in positional_wrapper
    return wrapped(*args, **kwargs)
TypeError: ('__init__() takes at least 3 arguments (1 given)', <class 'googleapiclient.errors.HttpError'>, ())

我该如何解决？
