Google Analytics Reporting API (Python) -如何获取上一页和下一页路径？

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

# 设置API凭据
credentials = service_account.Credentials.from_service_account_file(
    'path/to/your/credentials.json',
    scopes=['https://www.googleapis.com/auth/analytics.readonly']
)

# 创建Analytics Reporting对象
analytics = build('analyticsreporting', 'v4', credentials=credentials)

# 构建报告请求
request = {
    'viewId': 'your-view-id',
    'dateRanges': [{'startDate': '2022-01-01', 'endDate': '2022-01-31'}],
    'dimensions': [{'name': 'previousPagePath'}, {'name': 'nextPagePath'}],
    'metrics': [{'expression': 'ga:pageviews'}]
}

# 执行报告请求
response = analytics.reports().batchGet(body={'reportRequests': [request]}).execute()

# 获取报告数据
report_data = response['reports'][0]['data']['rows']

# 打印上一页和下一页路径及对应的页面浏览量
for row in report_data:
    previous_page_path = row['dimensions'][0]
    next_page_path = row['dimensions'][1]
    pageviews = row['metrics'][0]['values'][0]
    print(f"Previous Page Path: {previous_page_path}")
    print(f"Next Page Path: {next_page_path}")
    print(f"Pageviews: {pageviews}")
    print("------")
