创建和管理您的商品资源

创建商品集后，您可以创建商品并将它们添加到商品集。创建商品时，您必须提供相应商品的显示名和商品类别。目前支持的类别包括 homegoods-v2、apparel-v2、toys-v2、packagedgoods-v1 和 general-v1*。

您还可以根据需要提供商品说明和商品标签。标签是描述您的商品的键值对，如 color=black 或 style=mens。您可以添加标签，以过滤商品搜索结果，从而仅搜索特定商品图片。

创建商品

您可以使用在线导入功能来创建单件商品。创建商品后，您可以向其添加参考图片或将其添加到一个或多个商品集中。

REST 和命令行

在使用下面的任何请求数据之前，请先进行以下替换：

  • project-id：您的 GCP 项目 ID。
  • location-id：有效的位置标识符。有效的位置标识符包括 us-west1、us-east1、europe-west1 和 asia-east1。
  • display-name：您选择的字符串显示名。
  • product-description：您选择的字符串说明。
  • product-category：有效的商品类别。目前提供了以下商品类别：homegoods-v2、apparel-v2、toys-v2、packagedgoods-v1 和 general-v1。
  • productLabels：与商品关联的一个或多个键值对。每个 key-string 必须具有一个关联的 value-string。

HTTP 方法和网址： 

POST https://vision.googleapis.com/v1/projects/project-id/locations/location-id/products

请求 JSON 正文： 

{
  "displayName": "display-name",
  "description": "product-description",
  "productCategory": "product-category",
  "productLabels": [
      {
        "key": "key-string",
        "value": "value-string"
      }
  ]
}

如需发送请求，请选择以下方式之一：

curl

将请求正文保存在名为 request.json 的文件中，然后执行以下命令： 

curl -X POST \
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
-H "Content-Type: application/json; charset=utf-8" \
-d @request.json \
https://vision.googleapis.com/v1/projects/project-id/locations/location-id/products

PowerShell

将请求正文保存在名为 request.json 的文件中，然后执行以下命令： 

$cred = gcloud auth application-default print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
  -Method POST `
  -Headers $headers `
  -ContentType: "application/json; charset=utf-8" `
  -InFile request.json `
  -Uri "https://vision.googleapis.com/v1/projects/project-id/locations/location-id/products" | Select-Object -Expand Content

请求正文示例：

{
  "displayName": "sample-product-1234",
  "description": "Athletic shorts",
  "productCategory": "apparel-v2",
  "productLabels": [
      {
        "key": "style",
        "value": "womens"
      },
      {
        "key": "color",
        "value": "blue"
      }
  ]
}

如果请求成功，服务器将返回一个 200 OK HTTP 状态代码以及 JSON 格式的响应。

您应该会看到类似如下所示的输出。可以使用商品 ID（本例中为 37b9811d308c4e42）对商品执行其他操作。

{
  "name": "projects/project-id/locations/location-id/products/37b9811d308c4e42",
  "displayName": "sample-product-456",
  "description": "Athletic shorts",
