Question

我需要从Adwords到Python中获取关键字效果报告。我正在使用带有googleads库的服务帐户通过de Adwords API将Python连接到Adwords。在我尝试使用data_downloader.DownloadReportWithAwql下载报告之前，一切似乎都运行顺利。 “ AttributeError：'str'对象没有属性'CreateHttpHeader'”。

我正在使用adwords模块对服务帐户进行身份验证，然后使用相应的adwords客户端调用“ ReportDefinitionService”。之后，我将创建数据下载器对象并构建adwords查询，最后使用Awql下载报告。

我看过：

How To Pull Data From the Adwords API and put into a Pandas Dataframe

https://developers.google.com/adwords/api/docs/samples/python/reporting

https://github.com/googleads/googleads-python-lib/issues/253

https://developers.google.com/adwords/api/docs/reference/v201809/ReportDefinitionService

我没有MCC帐户访问权限（越来越难获得），但是我应该在Google Cloud中进行所有设置。这是我的代码：

from googleads import oauth2
from googleads import adwords
import pandas as pd
import numpy as np
import os



# Initialize the GoogleRefreshTokenClient

oauth2_client = oauth2.GoogleServiceAccountClient("marketing-analytics93839202-038212.json", oauth2.GetAPIScope('adwords'))

# Initialize the Adwords client.
adwords_client = adwords.AdWordsClient(oauth2_client, 'AdWords')
ad_report_service = adwords_client.GetService('ReportDefinitionService', 
version='v201809')


# Construct query

data_downloader = adwords_client.GetReportDownloader(version='v201809')



# Create report query.
 report_query = (adwords.ReportQueryBuilder()
              .Select('CampaignId', 'AdGroupId', 'Id', 'Criteria',
                      'Conversions', 'Impressions', 'Clicks','Ctr',
                      'Cost')
              .From('KEYWORDS_PERFORMANCE')
              .Where('Status').In('ENABLED', 'PAUSED')
              .During('LAST_30_DAYS')
              .Build())

# Up to this point there are no apparent errors. Now write the output

data_downloader.DownloadReportWithAwql(report_query, 
file_format='CSV',client_customer_id='xxx-xxx-xxxx',
skip_report_header=True, skip_column_header=False, 
skip_report_summary=True,include_zero_impressions=False)

>> AttributeError: 'str' object has no attribute 'CreateHttpHeader'

我得到AttributeError：'str'对象没有属性'CreateHttpHeader'。我希望查询的报告是熊猫数据框。

Answer 1

AdWordsClient的构造函数的签名为

def __init__(self, developer_token, oauth2_client,
               user_agent=_DEFAULT_USER_AGENT, soap_impl='zeep',
               timeout=3600, **kwargs):

您将oauth2_client实例用作developer_token参数，并在OAuth2客户端应该运行的地方传递'AdWords'：

adwords_client = adwords.AdWordsClient(oauth2_client, 'AdWords')

将开发者令牌添加为adwords.AdWordsClient的第一个参数后，错误就会消失：

adwords_client = adwords.AdWordsClient(DEV_TOKEN, oauth2_client, 'AdWords')

Answer 2

要将报告下载到熊猫数据框中，请使用以下方法：

oauth2_client = oauth2.GoogleServiceAccountClient("marketing-analytics93839202-038212.json", oauth2.GetAPIScope('adwords'))

# Initialize the Adwords client.
adwords_client = adwords.AdWordsClient(oauth2_client, 'AdWords')
# Define output as a string
output = io.StringIO()

report_downloader = adwords_client.GetReportDownloader(version='v201809')

# Create report query.
report_query = ('''
SELECT CampaignName, CampaignId, AdGroupId, AdGroupName,QueryMatchTypeWithVariant, Query,Cost,Clicks,Conversions,Impressions
from SEARCH_QUERY_PERFORMANCE_REPORT
WHERE CampaignId IN [''' + str(activeCampaignId) +''']''')

# Write query result to output file
report_downloader.DownloadReportWithAwql(
    report_query, 
    'CSV',
    output,
    #client_customer_id='xxx-xxx-xxx', # denotes which adw account to pull from
    skip_report_header=True, 
    skip_column_header=False,
    skip_report_summary=True, 
    include_zero_impressions=False)

output.seek(0)

df = pd.read_csv(output)

通过服务帐户连接的Python googleads库。错误：AttributeError：'str'对象没有属性'CreateHttpHeader'
