AMP页面中的Facebookpixel ViewContent

Question

我想添加脸书像素PagesView和ViewContent在我的放大器页面。

以下是我的代码：

<amp-analytics type="facebookpixel" id="facebook-pixel">
  <script type="application/json">
    {
      "vars": {
      "pixelId": "xy"
     },
     "triggers": {
       "trackPageview": {
          "on": "visible",
          "request": "pageview"
        },
        "trackViewContent": {
         "on": "visible",
         "request": "eventViewContent",
         "extraUrlParams": {
           "content_category": "open article"
         }
        }
      }
    }
  </script>
</amp-analytics>

页面视图可以工作，但是对于ViewContent，我总是在Facebook Pixel Helper中得到警告。从AMP到Facebook的POST请求是这样的：https://www.facebook.com/tr?noscript=1&ev=ViewContent&id=xy&cd%5Bvalue%5D=&cd%5Bcurrency%5D=&cd%5Bcontent_name%5D=open%20article&cd%5Bcontent_type%5D=&cd%5Bcontent_ids%5D=&dt=o4haxxaf7ij6ugv6b3p7cy2qybh9e8rd

所以它会向FB发送各种各样的空参数。Facebook像素的大多数标准事件参数都是可选的。我不希望他们发送所有的参数。我只想发送content_category..

Answer 1

使用img像素。示例：

<amp-pixel src="https://www.facebook.com/tr?id=&ev=ViewContent&noscript=1"
    layout="nodisplay"></amp-pixel>

Answer 2

使用以下配置：

<amp-analytics type="facebookpixel" id="facebook-pixel">
  <script type="application/json">
  {
    "vars": {
      "pixelId": "PIXEL_ID"
    },
    "triggers": {
      "trackPageview": {
        "on": "visible",
        "request": "pageview"
      },
      "trackViewContent": {
        "on": "visible",
        "request": "eventViewContent",
        "vars": {
          "product_catalog_id": "category_id",
          "currency": "EUR",
          "content_name": "content_name",
          "content_category": "content_category",
          "content_type": "product",
          "content_ids": "[1,2,3]",
          "value": "10"
        }
      }
    }
  }
  </script>
</amp-analytics>
