命令行

发送 PATCH 请求时,所有先前的字段及其值都将被清空,但 productCategory 字段除外,它是不可变的。发出 PATCH 更新请求后,发送您所需的包含值的所有字段。

在使用任何请求数据之前,请先进行以下替换:

  • PROJECT_ID:您的 Google Cloud 项目 ID。
  • LOCATION_ID:有效的位置标识符。有效的位置标识符包括 us-west1us-east1europe-west1asia-east1
  • PRODUCT_ID:与参考图片关联的商品的 ID。此 ID 由用户在创建商品时随机设置或指定。
  • display-name:您选择的字符串显示名。它可以与之前的显示名或更新后的值相同。
  • description:您选择的字符串说明。 它可以与之前的显示名或更新后的值相同。如果您不需要 description 字段和值,请忽略。
  • 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:

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

请求 JSON 正文:

{
  "displayName": "display-name",
  "description": "description",
  "productLabels": [
    {
      "key": "key-string",
      "value": "value-string"
    },
    {
      "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 PATCH \
-H "Authorization: Bearer $(gcloud auth print-access-token)" \
-H "x-goog-user-project: project-id" \
-H "Content-Type: application/json; charset=utf-8" \
-d @request.json \
"https://vision.googleapis.com/v1/projects/project-id/locations/location-id/products/product-id"

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 print-access-token
$headers = @{ "Authorization" = "Bearer $cred"; "x-goog-user-project" = "project-id" }

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

您应该收到类似以下内容的 JSON 响应:

{
  "name": "projects/project-id/locations/location-id/products/product-id",
  "displayName": "display-name",
  "description": "description",
  "productCategory": "apparel-v2",
  "productLabels": [
    {
      "key": "style",
      "value": "womens"
    },
    {
      "key": "onSale",
      "value": "true"
    }
  ]
}
