Google Analytics API 4:访问Python上的获取渠道数据

from googleapiclient.discovery import build

# 定义Google Analytics视图ID和API凭证文件路径
VIEW_ID = 'your-view-id'

# 通过API凭证文件构建Google Analytics服务对象
credentials = service_account.Credentials.from_service_account_file(KEY_FILE_LOCATION, scopes=['https://www.googleapis.com/auth/analytics.readonly'])

# 创建并执行获取渠道数据的请求

# 处理API响应并输出结果
