删除资源

您可以删除 API 创建的参考图片、商品或商品集资源。

删除单个资源

删除参考图片

您可以删除与商品关联的参考图片。

执行操作请求后，图片会标记为删除，但在下次编制索引之前仍保留在商品中。

此操作不会删除 Cloud Storage 中的实际图片文件。而是仅从商品中移除了对图片的引用。

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。
• 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。
• image-id：目标图片资源的 ID。

删除商品集

您还可以删除商品集。

删除某一商品集后，该商品集会立即从结果中移除。 但是，删除某一商品集不会移除该商品集中的个别商品，因为一个商品可能属于多个不同的商品集。此更改无需等到下次索引即会生效。

此操作不会删除 Cloud Storage 中的实际图片文件。API 创建的 ReferenceImage 资源不会被移除。

REST 和命令行

批量删除资源

您现在可以批量删除商品。批量删除商品的操作适用于以下商品类型：

• 特定商品集中的所有商品
• 不属于任何商品集的所有商品

为了避免出现并发操作错误，请等待此批量商品删除操作完成后再删除商品集。如果要重复使用清空的商品集，也要等到批量删除操作完成后再导入新商品。

对于单个商品而言，这些注意事项是相似的；您应该避免对批量删除操作涉及的任何单个商品执行操作。例如，您不应将这些商品中的任何商品添加到其他商品集中，因为它们最终会被删除。

批量删除 (purge) 操作无法撤消。如果您需要重新导入数据，则应该保留包含要删除商品的 CSV 以便进行批量导入。

删除商品集中的商品

您可以通过在请求中指定商品集 ID 来删除给定商品集中的所有商品。

系统会删除该商品集中的所有商品，无论它们是否属于其他商品集都是如此。

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。
• product-set-id：您要对其执行操作的商品集的 ID。

HTTP 方法和网址：

获取操作状态

您可以使用长时间运行的操作（如完全清除商品集或完全清除孤立商品）的 operation-id 来获取其状态。

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：

• 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。
• operation-id：您的操作的 ID。此 ID 是操作名称的最后一个元素。例如：
  • 操作名称：projects/project-id/locations/location-id/operations/bc4e1d412863e626
  • 操作 ID：bc4e1d412863e626

HTTP 方法和网址：

GET https://vision.googleapis.com/v1/locations/location-id/operations/operation-id

如需发送请求，请选择以下方式之一：

curl

注意：请确保已将 GOOGLE_APPLICATION_CREDENTIALS 环境变量设置为服务帐号私钥文件的路径。

执行以下命令：

curl -X GET \
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
https://vision.googleapis.com/v1/locations/location-id/operations/operation-id

PowerShell

注意：请确保已将 GOOGLE_APPLICATION_CREDENTIALS 环境变量设置为服务帐号私钥文件的路径。

执行以下命令：

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

Invoke-WebRequest `
  -Method GET `
  -Headers $headers `
  -Uri "https://vision.googleapis.com/v1/locations/location-id/operations/operation-id" | Select-Object -Expand Content

完成商品集完全清除操作后，您应会看到如下所示的输出：

  "name": "locations/location-id/operations/operation-id",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.vision.v1.BatchOperationMetadata",

      "productSetId": "project-set-id"
    },

}

完成孤立的商品完全清除操作后，您应会看到如下所示的输出：
