如何使用GA API搜索UTM参数

import google.auth
from google.auth.transport.requests import Request
from google.oauth2 import service_account
from googleapiclient.discovery import build

# 加载密钥文件
credentials = service_account.Credentials.from_service_account_file(
    'path/to/your/keyfile.json',
    scopes=['https://www.googleapis.com/auth/analytics.readonly']
)

# 创建API客户端
service = build('analyticsreporting', 'v4', credentials=credentials)

# 构建请求
request = {
    'viewId': 'your-view-id',
    'dateRanges': [{'startDate': '2022-01-01', 'endDate': '2022-01-31'}],
    'dimensions': [{'name': 'ga:sourceMedium'}, {'name': 'ga:campaign'}, {'name': 'ga:keyword'}],
    'metrics': [{'expression': 'ga:sessions'}],
    'filtersExpression': 'ga:medium==referral'
}

# 发送请求并获取响应
response = service.reports().batchGet(body={'reportRequests': [request]}).execute()

# 处理响应数据
for report in response['reports']:
    columnHeader = report['columnHeader']
    dimensionHeaders = columnHeader['dimensions']
    metricHeaders = columnHeader['metricHeader']['metricHeaderEntries']
    rows = report['data']['rows']

    for row in rows:
        dimensions = row['dimensions']
        metrics = row['metrics']

        for i, dimension in enumerate(dimensions):
            print(dimensionHeaders[i] + ': ' + dimension)

        for metric in metrics:
            values = metric['values']

            for j, value in enumerate(values):
                print(metricHeaders[j]['name'] + ': ' + value)
