ADC(应用程序默认凭据)工作流是否只支持Google Cloud API(例如,支持Google Cloud Storage API,而不支持Google Sheet API)?
我指的是
google.auth's default method
如果设置
GOOGLE_APPLICATION_CREDENTIALS
私有密钥文件的环境变量,比如key.json。这与
default
方法按照
google.auth
包裹:
1. If the environment variable GOOGLE_APPLICATION_CREDENTIALS is set to the path of a valid service account JSON private key file, then it is loaded and returned.
import google.auth
from apiclient import discovery
credentials, project_id = google.auth.default(scopes=['https://www.googleapis.com/auth/spreadsheets'])
sheets = discovery.build('sheets', 'v4', credentials=credentials)
SPREADSHEETID = '....'
result = sheets.spreadsheets().values().get(spreadsheetId=SPREADSHEETID, range='Sheet1!A:B').execute()
print result.get('values', [])
现在,看看方法的第4步:
4. If the application is running in Compute Engine or the App Engine flexible environment then the credentials and project ID are obtained from the Metadata Service.

环境变量在Google计算实例上,我得到以下错误:
googleapiclient.errors.HttpError: <HttpError 403 when requesting https://sheets.googleapis.com/v4/spreadsheets/..../values/Sheet1%21A%3AB?alt=json returned "Request had insufficient authentication scopes.">
