优化服务器端实验gtag.js

Question

Google优化服务器端事件的文档是为analytics.js编写的。有没有办法使用gtag.js来做同样的事情？https://developers.google.com/optimize/devguides/experiments

ga('set', 'exp', `${experimentId}.${variationId}`);
ga('send', 'pageview');

类似的东西

gtag('event', '???', {
???: `${experimentId}.${variantPosition}`,
});

Answer 1

此语法应该有效：

gtag('set', {'experiments': [{'id': 'exp_id', 'variant': '1'}]});

Answer 2

语法和文档链接已更新：

gtag('event', 'experiment_impression', {​
'experiment_id': '$experimentId',
'variant_id': '$experimentId.$variantid',
'send_to': 'GA_MEASUREMENT_ID',
});
