列出商品集

本部分介绍如何检索所有商品集的列表。

REST

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-west1、us-east1、europe-west1 和 asia-east1。

HTTP 方法和网址：

GET https://vision.googleapis.com/v1/projects/project-id/locations/location-id/productSets

如需发送请求，请选择以下方式之一：

curl

注意：以下命令假定您已使用您的用户账号通过运行 gcloud init 或 gcloud auth login 登录 gcloud CLI，或者使用了 Cloud Shell，这会使您自动登录 gcloud CLI。您可以运行 gcloud auth list 来检查当前活跃的账号。

执行以下命令：

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "x-goog-user-project: project-id" \
     "https://vision.googleapis.com/v1/projects/project-id/locations/location-id/productSets"

PowerShell

注意：以下命令假定您已使用您的用户账号通过运行 gcloud init 或 gcloud auth login 登录 gcloud CLI。您可以运行 gcloud auth list 来检查当前活跃的账号。

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 GET `
    -Headers $headers `
    -Uri "https://vision.googleapis.com/v1/projects/project-id/locations/location-id/productSets" | Select-Object -Expand Content

您应该收到类似以下内容的 JSON 响应：

列出商品集中的所有商品

以下示例展示了如何列出特定商品集中的商品。

REST

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-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：

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

如需发送请求，请选择以下方式之一：

curl

执行以下命令：

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "x-goog-user-project: project-id" \
     "https://vision.googleapis.com/v1/projects/project-id/locations/location-id/productSets/product-set-id/products"

PowerShell

注意：以下命令假定您已使用您的用户账号通过运行 gcloud init 或 gcloud auth login 登录 gcloud CLI。您可以运行 gcloud auth list 来检查当前活跃的账号。

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 GET `
    -Headers $headers `
    -Uri "https://vision.googleapis.com/v1/projects/project-id/locations/location-id/productSets/product-set-id/products" | Select-Object -Expand Content

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。请注意，一次返回的商品数量上限为 10。如果页数更多，则系统会提供 nextPageToken。

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

如需发送请求，请选择以下方式之一：

curl

执行以下命令：

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "x-goog-user-project: project-id" \
     "https://vision.googleapis.com/v1/projects/project-id/locations/location-id/products/product-id/referenceImages"

PowerShell

注意：以下命令假定您已使用您的用户账号通过运行 gcloud init 或 gcloud auth login 登录 gcloud CLI。您可以运行 gcloud auth list 来检查当前活跃的账号。

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 GET `
    -Headers $headers `
    -Uri "https://vision.googleapis.com/v1/projects/project-id/locations/location-id/products/product-id/referenceImages" | Select-Object -Expand Content

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。一次返回的默认图片数量为 10。如果页数更多，则系统会提供 nextPageToken。

以下响应适用于包含两张参考图片的商品。其中一张图片具有关联的边界框，而另一张图片没有边界多边形。
