尝试使用Google AnalyticsAPI（PHP）获得移动用户的百分比

Question

I am trying to get percentage of mobile users on a website using the Google Analytics API in PHP.

Per https://developers.google.com/analytics/devguides/reporting/core/v3/common-queries, I am pretty sure I am using the right dimensions/metrics (below):

dimensions=ga:mobileDeviceInfo,ga:source
metrics=ga:sessions,ga:pageviews,ga:sessionDuration

I get back an array of mobile devices (expected) but see no way to convert that into a percentage.

The first array element (not set) I assume is the non-mobile traffic, but the numbers simply don't add up ( non-mobile traffic / total number of sessions doesn't equal the % mobile in the Google Analytics dashboard).

Any ideas or examples.

Answer 1

Instead of using ga:mobileDeviceInfo, I would use ga:deviceCategory. This way you're able to see the number of sessions by Desktop, Tablet, Mobile. Does this match what you see in the interface?

dimensions=ga:deviceCategory
metrics=ga:sessions

Also bear in mind to make sure the date range/filters/segmentation of the API and the UI are the same.
