Golang和gcloud API:如何获取身份验证令牌

Because Google AutoML does not have a golang client, I have to use the AutoML http client. To do so, requires an auth token from google which comes from running the following cli command:

gcloud auth application-default print-access-token

I am currently authing my Golang server with a credentials json file that has access to AutoML as well (example usage)

storageClient, err := storage.NewClient(ctx, option.WithCredentialsFile(gcloudCredsJSONPath))

My question is: how would I get an auth token from the Golang Google client if I have a JSON credentials file? Is this even possible?

Thank you for any help!

    You can only use API tokens with certain Google Cloud APIs. Using tokens is discourage by Google Cloud as you can read in this article:

    https://cloud.google.com/docs/authentication/

    If your production environment is also Google Cloud, you might not need to use any JSON file at all. Google Cloud has the concept of "DefaultCredentials" that it injects in your services via the environment. You might be able to simplify your code to:

    storageClient, err := storage.NewClient(ctx)

    It's also recommended to use a "ServiceAccount" so the credentials that your application use can be scopes to it. You can read more here:
