如何在没有用户交互的情况下授权Google API？

Question

我试图运行自动每日API调用谷歌分析API

问题是，当我运行命令建立连接时，浏览器中会弹出一个窗口 我必须单击此处以允许访问我的项目

有没有人可以回避这一步，因为这一步在我的浏览器中需要一个可视化的界面和操作，我似乎无法每天在后台自动运行它

有什么建议吗

您应该考虑使用服务帐户。服务帐户与虚拟用户类似，您可以通过获取服务帐户电子邮件地址并将其添加为您希望访问的帐户上的用户，对服务帐户访问您的Google analytics帐户进行预授权。通过这样做，代码将不需要像您当前看到的那样由用户授权

服务帐户应仅用于开发人员拥有的帐户，而不应用于访问其他用户的帐户，因为您应该使用Oauth2

官方教程可以在这里找到Hello Analytics Reporting API v4; Python quickstart for service accounts

"""Hello Analytics Reporting API V4."""

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


SCOPES = ['https://www.googleapis.com/auth/analytics.readonly']
KEY_FILE_LOCATION = '<REPLACE_WITH_JSON_FILE>'
VIEW_ID = '<REPLACE_WITH_VIEW_ID>'


def initialize_analyticsreporting():
  """Initializes an Analytics Reporting API V4 service object.

  Returns:
    An authorized Analytics Reporting API V4 service object.
  """
  credentials = ServiceAccountCredentials.from_json_keyfile_name(
      KEY_FILE_LOCATION, SCOPES)

  # Build the service object.
  analytics = build('analyticsreporting', 'v4', credentials=credentials)

  return analytics


def get_report(analytics):
  """Queries the Analytics Reporting API V4.

  Args:

  """
  return analytics.reports().batchGet(
      body={
        'reportRequests': [
        {
          'viewId': VIEW_ID,
          'dateRanges': [{'startDate': '7daysAgo', 'endDate': 'today'}],

        }]
      }
  ).execute()


def print_response(response):
  """Parses and prints the Analytics Reporting API V4 response.

  Args:

  """
  for report in response.get('reports', []):
    columnHeader = report.get('columnHeader', {})
    dimensionHeaders = columnHeader.get('dimensions', [])
    metricHeaders = columnHeader.get('metricHeader', {}).get('metricHeaderEntries', [])

    for row in report.get('data', {}).get('rows', []):
      dimensions = row.get('dimensions', [])
      dateRangeValues = row.get('metrics', [])

      for header, dimension in zip(dimensionHeaders, dimensions):
        print(header + ': ', dimension)

      for i, values in enumerate(dateRangeValues):
        print('Date range:', str(i))
        for metricHeader, value in zip(metricHeaders, values.get('values')):
          print(metricHeader.get('name') + ':', value)

您需要在Google开发者控制台上创建服务帐户凭据。您现在使用的凭据将不起作用。这是一段关于How to create Google Oauth2 Service account credentials.的视频

记住在库下启用Google analytics Reporting api
