Enumera productos

Puedes ver todos los productos en un proyecto de Google Cloud Platform o en un conjunto de productos específico.

Enumera todos los productos de un proyecto

En el siguiente ejemplo, se muestra cómo enumerar productos en un proyecto.

LÍNEA DE CMD Y REST

Antes de usar cualquiera de los siguientes datos de solicitud, realiza estos reemplazos:

  • project-id: El ID de tu proyecto de GCP
  • location-id: Un identificador de ubicación válido. Los identificadores de ubicación válidos son: us-west1, us-east1, europe-west1 y asia-east1.

Método HTTP y URL:

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

Para enviar tu solicitud, elige una de estas opciones:

curl

Ejecuta el siguiente comando:

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

PowerShell

Ejecuta el siguiente comando:

$headers = @{ "Authorization" = "Bearer $cred" }

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

Si la solicitud se completa de forma correcta, el servidor muestra un código de estado HTTP 200 OK y la respuesta en formato JSON:

Deberías ver un resultado similar al siguiente. Ten en cuenta que la cantidad de productos que se muestran se limita a 10 por vez, y se proporciona un nextPageToken si hay más páginas.

Si se muestra un nextPageToken, puedes usar el token para obtener la siguiente página de los resultados de productos. Usa el nextPageToken del JSON de respuesta (jMGjEqhXMtN95vZz2g en este ejemplo) como una consulta de pageToken anexada a la URL de la solicitud:

Enumera todos los productos de un conjunto de productos

En el siguiente ejemplo, se muestra cómo enumerar productos en un conjunto de productos específico.

LÍNEA DE CMD Y REST

Antes de usar cualquiera de los siguientes datos de solicitud, realiza estos reemplazos:

  • project-id: El ID de tu proyecto de GCP
  • location-id: Un identificador de ubicación válido. Los identificadores de ubicación válidos son: us-west1, us-east1, europe-west1 y asia-east1.
  • product-set-id: Es el ID del conjunto de productos en el que deseas ejecutar la operación.

Método HTTP y URL:

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

Para enviar tu solicitud, elige una de estas opciones:

curl

Ejecuta el siguiente comando:

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

PowerShell

Ejecuta el siguiente comando:

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

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

Si la solicitud se completa de forma correcta, el servidor muestra un código de estado HTTP 200 OK y la respuesta en formato JSON:

Deberías ver un resultado similar al siguiente. Ten en cuenta que la cantidad de productos que se muestran se limita a 10 por vez, y se proporciona un nextPageToken si hay más páginas.

Si se muestra un nextPageToken, puedes usar el token para obtener la siguiente página de los resultados de productos. Usa el nextPageToken del JSON de respuesta (e5nEGpoVEZqlBbZRhQ en este ejemplo) como una consulta de pageToken anexada a la URL de la solicitud:

Obtén una sola imagen de referencia

También puedes obtener una sola imagen de referencia vinculada a un producto.

LÍNEA DE CMD Y REST

Antes de usar cualquiera de los siguientes datos de solicitud, realiza estos reemplazos:

  • project-id: El ID de tu proyecto de GCP
  • location-id: Un identificador de ubicación válido. Los identificadores de ubicación válidos son los siguientes: us-west1, us-east1, europe-west1 y asia-east1
  • product-id: El ID del producto asociado con una imagen de referencia. Este ID se establece de forma aleatoria, o el usuario lo especifica al momento de crear el producto.
  • image-id: Es el ID del recurso de la imagen de destino.

Método HTTP y URL:

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

Para enviar tu solicitud, elige una de estas opciones:

curl

Ejecuta el siguiente comando:

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

PowerShell

Ejecuta el siguiente comando:

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

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