目前 Shopify 安装GA4有几种方式？

• 1：在"偏好设置" 可以设置
• 2: 在"设置" 中的 ”客户事件“ 通过自定义Javascript沙箱代码可以设置
• 3：直接在代码中引入

问题： 重复设置 1,2 会导致部分事件重复提交到GA4的报告中，可以通过谷歌分析后台的”报告“ 中”实时“去验证，我自己测试的 add_to_cart，发现了重复的情况，由于 3 直接在更改代码是由开发人员控制，可以控制提交的时机，所以可以规避某些事件不上报到GA4，也可以自由的自定义一些事件去上报到GA4

第一种

    - page_view
    - search
    - view_item
    - add_to_cart
    - begin_checkout
    - add_payment_info
    - purchase

目前shopify安装GA4后测试的方式？

• 1: 安装插件taga ssistant

• 2：可以通过谷歌分析 ”设置“ - ”媒体资源管理“ - ”DebugView“ 观察，或者 实时报告查看事件

注意： 通过自定义Javascript沙箱代码，在 ”DebugView“ 中是无法验证的
