管理长时间运行的操作

本页介绍了如何管理 Financial Services API 长时间运行的操作 (LRO) 的生命周期。

如果方法调用可能需要很长时间才能完成,系统就会返回长时间运行的操作。例如,Financial Services API 会在您每次调用 projects.locations.instances.create 时创建一个 LRO。LRO 会跟踪处理作业的状态。

您可以使用 Financial Services API 提供的 projects.locations.operations 方法来检查 LRO 的状态。您还可以对 LRO 执行 listcanceldelete 操作。

LRO 会在 Google Cloud 项目和位置层级上加以管理。 向该 API 发出请求时,请在其中提供 Google Cloud 项目以及 LRO 的运行位置。

在 LRO 完成之后,LRO 的记录会保留大约 30 天。在这段时间之后,您将无法再查看或列出 LRO。

获取长时间运行的操作的详细信息

假设您创建了一个实例。响应中的 name 值表明,Financial Services API 创建了一个名为 projects/PROJECT_ID/locations/LOCATION/operations/OPERATION_ID 的 LRO。

使用 projects.locations.operations.get 方法检查实例是否已创建。如果响应包含 "done": false,请重复该命令,直到响应包含 "done": true。此操作可能需要几分钟才能完成。

您还可以通过列出长时间运行的操作来检索 LRO 名称。

在使用任何请求数据之前,请先进行以下替换:

  • PROJECT_IDIAM 设置中列出的 Google Cloud 项目 ID
  • LOCATION:实例的位置;请使用某个受支持的地区
    显示位置
    • us-central1
    • us-east1
    • asia-south1
    • europe-west1
    • europe-west2
    • europe-west4
    • northamerica-northeast1
    • southamerica-east1
    • australia-southeast1
  • OPERATION_ID:操作的标识符

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)" \
"https://financialservices.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/operations/OPERATION_ID"

PowerShell

执行以下命令:

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

Invoke-WebRequest `
-Method GET `
-Headers $headers `
-Uri "https://financialservices.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/operations/OPERATION_ID" | Select-Object -Expand Content

您应该收到类似以下内容的 JSON 响应:

  }
}

列出长时间运行的操作

使用 projects.locations.operations.list 方法可列出指定位置中的所有操作。

在使用任何请求数据之前,请先进行以下替换:

  • PROJECT_IDIAM 设置中列出的 Google Cloud 项目 ID
  • LOCATION:操作的位置;请使用某个受支持的地区
    显示位置
    • us-central1
    • us-east1
    • asia-south1
    • europe-west1
    • europe-west2
    • europe-west4
    • northamerica-northeast1
    • southamerica-east1
    • australia-southeast1

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)" \
"https://financialservices.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/operations"

PowerShell

执行以下命令:

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

Invoke-WebRequest `
-Method GET `
-Headers $headers `
-Uri "https://financialservices.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/operations" | Select-Object -Expand Content

您应该收到类似以下内容的 JSON 响应:

  "operations": [
    {
      "name": "projects/PROJECT_ID/locations/LOCATION/operations/OPERATION_ID",
      "metadata": {
        "@type": "type.googleapis.com/google.cloud.financialservices.v1.OperationMetadata",
        "createTime": "2023-03-14T15:52:55.358979323Z",

取消长时间运行的操作

使用 projects.locations.operations.cancel 方法对长时间运行的操作启动异步取消。服务器会尽全力取消操作,但不能保证一定成功。

在使用任何请求数据之前,请先进行以下替换:

  • PROJECT_IDIAM 设置中列出的 Google Cloud 项目 ID
  • LOCATION:操作的位置;请使用某个受支持的地区
    显示位置
    • us-central1
    • us-east1
    • asia-south1
    • europe-west1
    • europe-west2
    • europe-west4
    • northamerica-northeast1
    • southamerica-east1
    • australia-southeast1
  • OPERATION_ID:操作的标识符

如需发送请求,请选择以下方式之一:

curl

执行以下命令:

curl -X POST \
-H "Authorization: Bearer $(gcloud auth print-access-token)" \
-H "Content-Type: application/json; charset=utf-8" \
-d "" \
"https://financialservices.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/operations/OPERATION_ID:cancel"

PowerShell

执行以下命令:

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

Invoke-WebRequest `
-Method POST `
-Headers $headers `
-Uri "https://financialservices.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/operations/OPERATION_ID:cancel" | Select-Object -Expand Content

您应该收到类似以下内容的 JSON 响应:

{}

删除长时间运行的操作

使用 projects.locations.operations.delete 方法可删除已完成的长时间运行的操作。此方法只是表明客户端不再关注操作结果,而不会取消操作。

在使用任何请求数据之前,请先进行以下替换:

  • PROJECT_IDIAM 设置中列出的 Google Cloud 项目 ID
  • LOCATION:操作的位置;请使用某个受支持的地区
    显示位置
    • us-central1
    • us-east1
    • asia-south1
    • europe-west1
    • europe-west2
    • europe-west4
    • northamerica-northeast1
    • southamerica-east1
    • australia-southeast1
  • OPERATION_ID:操作的标识符

如需发送请求,请选择以下方式之一:

curl

执行以下命令:

curl -X DELETE \
-H "Authorization: Bearer $(gcloud auth print-access-token)" \
"https://financialservices.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/operations/OPERATION_ID"

PowerShell

执行以下命令:

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