google-cloud-platform - google-cloud-recommendation 如何获取预测的下一页？

Question

我想使用预测方法来获得按页面划分的推荐。此方法具有pageToken用于分页的参数。该参数应在先前的预测响应中接收。但是 v2 API 中的这个方法不返回pageToken或者nextPageToken在 v1beta1 API 中。为什么消失了？如何获得下一页进行预测？

请求网址是 https://retail.googleapis.com/v2/projects/{PROJECT_NUMBER}/locations/global/catalogs/default_catalog/placements/recently_viewed_default:predict

请求正文是

{
  "filter": "tag=(\"成人作品\") filterOutOfStockItems",
  "userEvent": {
    "eventType": "home-page-view",
    "visitorId": "1254704470.1607003607",
    "productDetails": [
      {
        "product": {
          "id": "220604"
        },
        "quantity": 1
      }
    ]
  }
}

回复在这里。没有nextPageToken

{
  "results": [
    {
      "id": "170706"
    },
    {
      "id": "64081"
    },
          :
       (snip)
          :
    {
      "id": "132940"
    },
    {
      "id": "17557"
    }
  ],
  "attributionToken": "ChQxNzkzOTg1NDI3MTk1OTMyNzU0MhACGiNvZnRlbl9wdXJjX2ZyZXF1ZW50bHlfMTYxNDMwNjk3OTQyNSIYb2Z0ZW5fcHVyY2hhc2VkX3RvZ2V0aGVyKAA"
