先在Shopify后台设置把Customer Privacy征求弹框打开。
然后在theme.liquid的<head>开始处添加下面代码，以向GA4发送数据。
<script>
window.dataLayer = window.dataLayer || [];
function gtag() { dataLayer.push(arguments); }
var c = document.cookie.split("; ");
// var s = c.filter(c=>c.startsWith("receive-cookie-deprecation="))[0];
var s = c.filter(c=>c.startsWith("_gcl_au="))[0];
if(s==undefined){
gtag('consent', 'default', {
'analytics_storage': 'denied',
'ad_storage': 'denied',
'ad_user_data': 'denied',
'ad_personalization': 'denied',
'region':['AT','BE','BG','CY','CZ','DE','DK','EE','ES','FI','FR','GR','HR','HU','IE','IS','IT','LI','LT','LU','LV','MT','NL','NO','PL','PT','RO','SE','SI','SK'],
});
} else {
gtag('consent', 'update', {
'analytics_storage': 'granted',
'ad_storage': 'granted',
'ad_user_data': 'granted',
'ad_personalization': 'granted'
});
}
</script>
<script>
document.addEventListener('click', function(e){
if(e.target.innerText.includes("Accept")){
gtag('consent', 'update', {
'analytics_storage': 'granted',
'ad_storage': 'granted',
'ad_user_data': 'granted',
'ad_personalization': 'granted'
});
}else if(e.target.innerText.includes("Decline")){
gtag('consent', 'update', {
'analytics_storage': 'denied',
'ad_storage': 'denied',
'ad_user_data': 'denied',
'ad_personalization': 'denied'

}
});
</script>
