我正在尝试使用 Python 查询 Google Analytics API。我已经按照文档中的示例进行操作。（我做了非常小的改动来帮助我调试我遇到的问题）。我不断得到一个“NoneType”对象没有属性“ __ getitem __ ”，我似乎无法解释。我只是按照 Google 提供的文档中的示例尝试获取 2012 年 3 月 3 日的 ga:visits 数据。
我正在运行的代码是：
#!/usr/bin/python
# -*- coding: utf-8 -*-
import sys
# import the Auth Helper class
import hello_analytics_api_v3_auth
from apiclient.errors import HttpError
from oauth2client.client import AccessTokenRefreshError
def main(argv):
# Step 1. Get an analytics service object.
print "I got here twice"
service = hello_analytics_api_v3_auth.initialize_service()
try:
# Step 2. Get the user's first profile ID.
profile_id = get_first_profile_id(service)
print profile_id
if profile_id:
# Step 3. Query the Core Reporting API.
results = get_results(service, profile_id)
print "I got the results"
# Step 4. Output the results.
print_results(results)
print "I printed the results"
except TypeError, error:
# Handle errors in constructing a query.
print ('There was an error in constructing your query : %s' % error)
except HttpError, error:
# Handle API errors.
print ('Arg, there was an API error : %s : %s' %
(error.resp.status, error._get_reason()))
except AccessTokenRefreshError:
# Handle Auth errors.
print ('The credentials have been revoked or expired, please re-run '
'the application to re-authorize')
def get_first_profile_id(service):
# Get a list of all Google Analytics accounts for this user
print "I am trying to get first profile ID"
accounts = service.management().accounts().list().execute()
if accounts.get('items'):
# Get the first Google Analytics account
firstAccountId = accounts.get('items')[0].get('id')
# Get a list of all the Web Properties for the first account
webproperties = service.management().webproperties().list(accountId=firstAccountId).execute()
if webproperties.get('items'):
# Get the first Web Property ID
firstWebpropertyId = webproperties.get('items')[0].get('id')
# Get a list of all Profiles for the first Web Property of the first Account
profiles = service.management().profiles().list(
accountId=firstAccountId,
webPropertyId=firstWebpropertyId).execute()
if profiles.get('items'):
# return the first Profile ID
return profiles.get('items')[0].get('id')
return None
def get_results(service, profile_id):
# Use the Analytics Service Object to query the Core Reporting API
return service.data().ga().get(
ids='ga:' + profile_id,
start_date='2012-03-03',
##The start date dates range is hard coded here
##We have to change this so it becomes an input parameter
end_date='2012-03-03',
##The end date is also hard coded in
##Change this to be an input parameter
##If you run out of ideas, read the start date off a txt file
##And then have the user change the text file before running
##the program
metrics='ga:visits').execute()
def print_results(results):
# Print data nicely for the user.
print results
if results:
print 'First Profile: %s' % results.get('profileInfo').get('profileName')
print 'Total Visits: %s' % results.get('rows')[0][0]
else:
print 'No results found'
##if __name__ == '__main__':
main(sys.argv)
这将返回以下结果：
I got here twice
I am trying to get first profile ID
REDACT PROFILE ID
I got the results

There was an error in constructing your query : 'NoneType' object has no attribute '__getitem__'
任何人都可以通过解释出了什么问题并向我们展示我们需要解决的问题来帮助我们吗？:)
谢谢
