[英]How do you get gcloud access token in Python?
我希望在 Python 中执行以下等效操作,而不必使用os.system
东西调用这些命令并查看输出。
export GOOGLE_APPLICATION_CREDENTIALS="/path/to/credentials.json"
export PROJECT_ID="my-project-name"
gcloud auth application-default print-access-token
这可以用 Google SDK 完成吗?
我认为您可以使用Google Auth Library来做到这一点。 您可以使用pip
安装它:
$ pip install google-auth
这是使用存储桶的示例代码:
from google.oauth2 import service_account
from google.cloud import storage
KEY='/path/to/key.json'
PROJECT='your_project_id'
# gcloud auth application-default print-access-token is no necessary
credentials = service_account.Credentials.from_service_account_file(KEY)
# Initialize the Cloud Storage client using the credentials
storage_client = storage.Client(PROJECT,credentials)
# List objects in a bucket
blobs = storage_client.list_blobs("a_bucket")
for blob in blobs:
print(blob.name)
祝你编码好运!
使用蟒蛇:
import request
requests.get('http://metadata.google.internal/computeMetadata/v1/instance/service-accounts/default/token').json().get('access_token')
答案在这里:
import google.auth
import google.auth.transport.requests
from google.oauth2 import service_account
from os.path import expanduser
from os import getenv
# The the service account key ABSOLUTE path from env or current folder
service_account_key = getenv(
'GOOGLE_APPLICATION_CREDENTIALS',
f'{expanduser(".")}/service-account-key.json'
)
# Creates a credentials object from the service account file
credentials = service_account.Credentials.from_service_account_file(
service_account_key, # key path
scopes=['https://www.googleapis.com/auth/cloud-platform'] # scopes
)
# Prepare an authentication request
auth_req = google.auth.transport.requests.Request()
# Request refresh tokens
credentials.refresh(auth_req)
# now we can print the access token
print(credentials.token)
