在AppEngine / Go中获取当前部署的时间戳

Question

Can I get the deployed timestamp of current application version in AppEngine/Go?

It seems helpful, but not sure how to implement in AppEngine/Go application code.

• AppEngine: Get current serving application version
• https://godoc.org/google.golang.org/appengine
• https://cloud.google.com/appengine/docs/admin-api/v1beta2/reference/apps/modules/versions

Answer 1

From this link AppEngine: Get current serving application version, the suggested answer is written in python

os.environ['CURRENT_VERSION_ID']

Above code is trying to retrieve the environment variable with name CURRENT_VERSION_ID, Equivalent code in go would be:

import (
    ...
    "os"
)
...
versionText := os.Getenv("CURRENT_VERSION_ID")

According to one of the comments, the result would be in this format my-version.383096322806301043, you should use strings.Split method to split it by ., eg:

import (
    ...
    "strings"
)
...
timestampString := strings.Split(versionText, ".")[1]
