从Google Cloud中的操作名称轮询长时间运行的操作的Python方法? [英] Python way of polling longrunning operations from operation name in Google Cloud?

问题描述

我正在调用Google Cloud Function，该函数返回实现google.longrunning.Operations接口的Operation对象.我想从另一个仅接收操作名称(将无法访问操作对象本身)的Python进程中轮询该操作.所以我需要类似的东西:

I'm calling a Google Cloud Function that returns an Operation object implementing the google.longrunning.Operations interface. I want to poll this operation from another Python process that will only receive the operation name (will not have access to the operation object itself). So I need something like:

operation = getOperation(operationName)
isdone = operation.done()

AFAIK，您无法执行上面的第一步.我在这里找不到它: https://google- cloud-python.readthedocs.io/en/stable/core/operation.html

AFAIK, you can't do the first step above. I haven't found it here: https://google-cloud-python.readthedocs.io/en/stable/core/operation.html

我想按照文档中有关google.longrunning界面(

I would like to do what is explained in the docs about the google.longrunning interface (https://cloud.google.com/speech-to-text/docs/reference/rpc/google.longrunning#google.longrunning.Operations.GetOperation):

rpc GetOperation(GetOperationRequest) returns (Operation)

GetOperationRequest仅需要操作名称的地方.是否可以使用google-cloud-python库中的函数重新创建"操作?

Where the GetOperationRequest simply requires the operation name. Is there a way to "re-create" an operation using functions from the google-cloud-python library?

推荐答案

您可以使用:

from google.api_core import operations_v1
api = operations_v1.OperationsClient()
name = ...
response = api.get_operation(name)
