如何修改后台Cloud Function的Google Cloud Pub/Sub订阅确认截止日期 [英] How to modify Google Cloud Pub/Sub subscription acknowledgement deadline for background Cloud Function

问题描述

通过以下方式为Cloud Pub/Sub部署后台Cloud Function时:

When deploying a background Cloud Function for Cloud Pub/Sub via:

gcloud functions deploy function_name --runtime python37 --trigger-topic some_topic

使用推送端点(可能是App Engine标准端点)会自动创建订阅，但据称这些订阅不需要 域验证 https://cloud.google.com/pubsub/docs/push#其他端点).

A subscription gets automatically created with a push endpoint (likely App Engine standard endpoint, but those are claimed to be without the need of domain verification https://cloud.google.com/pubsub/docs/push#other-endpoints).

对于生成的订阅/端点，似乎没有注册/验证域的方法 ( https://www.google.com/webmasters/verification ，

For the generated subscription/endpoint there doesn't seem like a way to register/verify the domain (https://www.google.com/webmasters/verification, https://console.cloud.google.com/apis/credentials/domainverification)

结果，用户无法更改订阅，例如:

As a result the user cannot alter the subscription, for instance:

gcloud alpha pubsub subscriptions update some_subscription --ack-deadline=10

将产生类似"INVALID_ARGUMENT:提供的HTTP URL未在订阅的父项目中注册"的信息

Would yield something like "INVALID_ARGUMENT: The supplied HTTP URL is not registered in the subscription's parent project"

通过GCP上的Web界面执行此操作也会产生错误:"pubsub错误INVALID_ARGUMENT"

Doing it via the web interface on GCP would also yield an error: "pubsub error INVALID_ARGUMENT"

推荐答案

通过Cloud Functions连接到Cloud Pub/Sub主题时，将代表您创建订阅.此订阅由Cloud Functions管理，因此无法更新确认截止日期.

When connecting to a Cloud Pub/Sub topic via Cloud Functions, a subscription is created on your behalf. This subscription is managed by Cloud Functions and therefore it is not possible to update the acknowledgement deadline.
