我们应该如何创建通过Python连接到google analytics的凭据？

from google.oauth2 import service_account
from googleapiclient.discovery import build

# 读取凭据JSON文件
credentials = service_account.Credentials.from_service_account_file('path/to/credentials.json')

# 创建Google Analytics Reporting API客户端
analytics = build('analyticsreporting', 'v4', credentials=credentials)

# 使用API进行数据请求
response = analytics.reports().batchGet(
  body={
    'reportRequests': [
      {
        'viewId': 'YOUR_VIEW_ID',
        'dateRanges': [{'startDate': '2022-01-01', 'endDate': '2022-01-31'}],
        'metrics': [{'expression': 'ga:sessions'}],
        'dimensions': [{'name': 'ga:country'}]
      }
    ]
  }
).execute()

# 处理API响应数据
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', [])

  for row in rows:
    dimensions = row.get('dimensions', [])
    metrics = row.get('metrics', [])

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

    for metricHeader, metric in zip(metricHeaders, metrics):
      print(metricHeader.get('name') + ': ' + metric.get('values')[0])
