如何从Google Analytics Reporting API v4 Python获取前50个会话

Question

I've got an analytics reporting api v4 script in Python which returns to me the sessions for certain landing pages and which city the sessions have come from.

Is there a way to limit this to only the top 50 city locations per landing page for sessions so I don't get returned the city's that are landing on them which have like 1 session for example.

Here is the base code for the analytics request:

api_client = google_build(serviceName=api_name, version=api_version, 
http=authorized)
for i in developments:
sample_request = {
      'viewId': '6690350',
      'pageSize': 100000,
      'dateRanges': {
          'startDate': datetime.strftime(datetime.now() - timedelta(days = 30),'%Y-%m-%d'),
          'endDate': datetime.strftime(datetime.now(),'%Y-%m-%d')

      },
      'metrics': [{'expression': 'ga:sessions'}],
      'orderBys':
        [
            {'fieldName': 'ga:pagePath', 'sortOrder': 'ASCENDING'},
            {'fieldName': 'ga:sessions', 'sortOrder': 'DESCENDING'}
        ],
      'dimensions': [{'name': 'ga:pagePath'},{'name': 'ga:city'},{'name': 'ga:latitude'},{'name': 'ga:longitude'}],
      'dimensionFilterClauses' : [
        {

Answer 1

EDIT - To get top x cities for a particular landing page is not feasible through a single query, you will have to either use Content Grouping feature or process the broader response to achieve this.

Original response - Added to your code might not be complete, look at metricFilterClauses section added only

You can get the top 50 results by using pagination and using PageSize to restrict the number of rows that you get. Just make sure to use ordering to sort before you apply pagination.

You will have to use batchGet request to execute this - link to official guide of batchquest

api_client = google_build(serviceName=api_name, version=api_version, 
http=authorized)
for i in developments:
sample_request = {
      'viewId': '6690350',
      'pageSize': 100000,
      'dateRanges': {
          'startDate': datetime.strftime(datetime.now() - timedelta(days = 30),'%Y-%m-%d'),
          'endDate': datetime.strftime(datetime.now(),'%Y-%m-%d')

      },
      'metrics': [{'expression': 'ga:sessions'}],
       #add this metric filter to filter out with session more than 50 
      'metricFilterClauses': [{
          "filters": [{
              "metricName": "ga:sessions",
              "operator": "GREATER_THAN",
              "comparisonValue": "50"
          }]
      }]         
      'orderBys':
        [
            {'fieldName': 'ga:pagePath', 'sortOrder': 'ASCENDING'},
            {'fieldName': 'ga:sessions', 'sortOrder': 'DESCENDING'}
        ],
      'dimensions': [{'name': 'ga:pagePath'},{'name': 'ga:city'},{'name': 'ga:latitude'},{'name': 'ga:longitude'}]
       #top 50 results  
      'pageSize': 50

You can use MetricFilterClauses to filter out particular metric that you need. You can use different operators available to you to filter out based on conditions you want to use.
