取得作業狀態

您要求的多項作業都是長時間執行的作業,例如透過大量匯入建立產品組合、清除產品組合,以及清除孤立產品。這類要求會傳回 JSON,其中包含作業 ID,可用於取得作業狀態。

舉例來說,批次刪除 (purge) 要求會傳回下列 JSON:

{
"name": "projects/project-id/locations/location-id/operations/bc4e1d412863e626"
}

在本例中,作業 ID 為 bc4e1d412863e626。下列範例說明如何使用這個 ID 取得這項作業的狀態。

REST

使用任何要求資料之前,請先替換以下項目:

  • PROJECT_ID:您的 Google Cloud 專案 ID。
  • LOCATION_ID:有效的地點 ID。有效的位置識別碼包括:us-west1us-east1europe-west1asia-east1
  • OPERATION_ID:作業 ID。ID 是作業名稱的最後一個元素。舉例來說:
    • 作業名稱:projects/PROJECT_ID/locations/LOCATION_ID/operations/bc4e1d412863e626
    • 作業 ID:bc4e1d412863e626

HTTP 方法和網址:

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

如要傳送要求,請選擇以下其中一個選項:

curl

執行下列指令:

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

PowerShell

執行下列指令:

$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/locations/location-id/operations/operation-id" | Select-Object -Expand Content
