使用 python 脚本生成 google Admob 网络报告时获取 HttpError 401

Question

下面是我用来生成 Admob 网络报告的代码

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


base_path=os.path.dirname(os.path.realpath(__file__))
scopes=['https://www.googleapis.com/auth/admob.report']
key_file_location = base_path+'/config/service_account.json'

credentials = ServiceAccountCredentials.from_json_keyfile_name(key_file_location, scopes)



account_id='accounts/pub-XXXXXXXXXXXXXXXX'
network_report_filter = {
  'dateRange': {
    'startDate': {'year': 2020, 'month': 1, 'day': 1},
    'endDate': {'year': 2020, 'month': 2, 'day': 10}
  },
  'dimensions': ['DATE', 'APP', 'COUNTRY'],
  'metrics': ['CLICKS', 'ESTIMATED_EARNINGS'],
  'dimensionFilters': [
    {
      'dimension': 'COUNTRY',
      'matchesAny': {'values': [{'value': 'US', 'value': 'CN'}]}
    }
  ],
  'sortConditions': [
    {'dimension':'APP', 'order': 'ASCENDING'},
    {'metric':'CLICKS', 'order': 'DESCENDING'}
  ],
  'localizationSettings': {
    'currencyCode': 'USD',
    'languageCode': 'en-US'
  }
}


# Build the service object.
admob = build('admob', 'v1', credentials=credentials)

admob._resourceDesc=network_report_filter
accounts=admob.accounts()
network_report=accounts.networkReport().generate(parent=account_id)
data=network_report.execute()

它会抛出以下错误

*** HttpError: https://admob.googleapis.com/v1/accounts/pub-XXXXXXXXXXXXXXXX/networkReport:generate?alt=json 返回“请求缺少所需的身份验证凭据。预期的 OAuth 2 访问令牌、登录 cookie或其他有效的身份验证凭据。请参阅https://developers.google.com/identity/sign-in/web/devconsole-project。">

我已在启用 Admob API 的情况下生成服务帐户凭据。 但无法弄清楚为什么会出现身份验证错误。

Answer 1

主要问题是，上面的代码尝试使用服务帐户来查询 api。但是，它不受支持。可以通过OAuth2.0 Client Id查询。

OAth2.0 Client ID生成步骤：

• 打开项目的凭据页面 (https://console.cloud.google.com/apis/credentials?project=REPLACE_WITH_YOUR_PROJECT_ID)；
• 生成 OAuth2.0 客户端 ID；
• 下载生成的 json 文件；
• 在下面的代码中使用它；

以下内容对我很有效：

库：

pip3 install --upgrade google-api-python-client --user
pip3 install --upgrade oauth2client --user

代码示例：

import csv
import sys

from googleapiclient import discovery
from googleapiclient.http import build_http
from oauth2client import tools
from oauth2client.file import Storage
from oauth2client.client import OAuth2WebServerFlow


class AdMobAPI:

    def __init__(self):
        scope = 'https://www.googleapis.com/auth/admob.report'
        name = 'admob'
        version = 'v1'

        flow = OAuth2WebServerFlow(client_id='<todo: replace with a client_id from the secret json>',
                                   client_secret='<todo: replace with a secret from the secret json>',
                                   scope=scope)
        storage = Storage(name + '.dat')
        credentials = storage.get()
        if credentials is None or credentials.invalid:
            credentials = tools.run_flow(flow, storage)
        http = credentials.authorize(http=build_http())
        self.admob = discovery.build(name, version, http=http)

    # Convert to the list of dictionaries
    def report_to_list_of_dictionaries(self, response):

        for report_line in response:

                print(report_line)
                row = report_line.get('row')
                dm = {}
                if row.get('dimensionValues'):
                    for key, value in row.get('dimensionValues').items():

                result.append(dm)
        return result

        dimensions = ['DATE', 'APP', 'PLATFORM', 'COUNTRY']
        metrics = ['ESTIMATED_EARNINGS', 'IMPRESSIONS', 'CLICKS',
                   'AD_REQUESTS', 'MATCHED_REQUESTS']
        sort_conditions = {'dimension': 'DATE', 'order': 'DESCENDING'}
        report_spec = {'dateRange': date_range,

api = AdMobAPI()
raw_report = api.generate_report('<todo: replace with publisher id, smth like pub-[0-9]+>')
report_as_list_of_dictionaries = api.report_to_list_of_dictionaries(raw_report)

# Convert to CSV
dict_writer = csv.DictWriter(sys.stdout, report_as_list_of_dictionaries[0].keys())
dict_writer.writeheader()
dict_writer.writerows(report_as_list_of_dictionaries)

Answer 2

目前，google admob api 不支持服务帐号
