How do I update my Python Google Sheet API credentials code to avoid package depreciation?

The Google Sheets API Python Quickstart currently uses deprecated packages in its example code, where the use of oauth2client and httplib2 rather than google-auth and google-auth-oauthlib (or maybe google-auth?) is outdated or soon to be.

oauth2client

httplib2

google-auth

google-auth-oauthlib

google-auth

How do I rewrite this code to use these new libraries in a way that best anticipates their current state and the eventual move to google-auth, etc.? In particular, is there a simple reimplementation of retrieval, storage, and use of credentials in the quickstart (below) that brings it up to date?

google-auth

from __future__ import print_function
import httplib2
import os

from apiclient import discovery
from oauth2client import client
from oauth2client import tools
from oauth2client.file import Storage

try:
import argparse
flags = argparse.ArgumentParser(parents=[tools.argparser]).parse_args()
except ImportError:
flags = None

SCOPES = 'https://www.googleapis.com/auth/spreadsheets.readonly'
CLIENT_SECRET_FILE = 'client_secret.json'
APPLICATION_NAME = 'Google Sheets API Python Quickstart'


def get_credentials():
home_dir = os.path.expanduser('~')
credential_dir = os.path.join(home_dir, '.credentials')
if not os.path.exists(credential_dir):
os.makedirs(credential_dir)
credential_path = os.path.join(credential_dir, 'sheets.googleapis.com-python-quickstart.json')

store = Storage(credential_path)
credentials = store.get()
if not credentials or credentials.invalid:
flow = client.flow_from_clientsecrets(CLIENT_SECRET_FILE, SCOPES)
flow.user_agent = APPLICATION_NAME
if flags:
credentials = tools.run_flow(flow, store, flags)
else: # Needed only for compatibility with Python 2.6
credentials = tools.run(flow, store)
print('Storing credentials to ' + credential_path)
return credentials

def main():
credentials = get_credentials()
http = credentials.authorize(httplib2.Http())
discoveryUrl = 'https://sheets.googleapis.com/$discovery/rest?version=v4'
service = discovery.build('sheets', 'v4', http=http, discoveryServiceUrl=discoveryUrl)
# etc. ...

How about this answer? I prepared the sample script for the Quickstart of Sheets API.

client_secret.json

sheets.googleapis.com-python-quickstart.json

import copy
import json
import os
import pprint

import google.oauth2.credentials
from googleapiclient.discovery import build
from google_auth_oauthlib.flow import InstalledAppFlow

pp = pprint.PrettyPrinter(indent=2)

CLIENT_SECRETS_FILE = "client_secret.json"

SCOPES = ['https://www.googleapis.com/auth/spreadsheets.readonly']
API_SERVICE_NAME = 'sheets'
API_VERSION = 'v4'


def get_authenticated_service():
credential_path = os.path.join("./", 'sheets.googleapis.com-python-quickstart.json')
if os.path.exists(credential_path):
with open(credential_path, 'r') as f:
credential_params = json.load(f)
credentials = google.oauth2.credentials.Credentials(
credential_params["access_token"],
refresh_token=credential_params["refresh_token"],
token_uri=credential_params["token_uri"],
client_id=credential_params["client_id"],
client_secret=credential_params["client_secret"]
)
else:
flow = InstalledAppFlow.from_client_secrets_file(CLIENT_SECRETS_FILE, SCOPES)
credentials = flow.run_console()
with open(credential_path, 'w') as f:
p = copy.deepcopy(vars(credentials))
del p["expiry"]
json.dump(p, f, indent=4)
return build(API_SERVICE_NAME, API_VERSION, credentials=credentials)


def spreadsheets_get(service):
spreadsheetId = "### spreadsheet ID ###"
rangeName = "Sheet1!a1:a10"
results = service.spreadsheets().get(
spreadsheetId=spreadsheetId,
ranges=rangeName
).execute()
pp.pprint(results)


if __name__ == '__main__':
os.environ['OAUTHLIB_INSECURE_TRANSPORT'] = '1'
service = get_authenticated_service()
spreadsheets_get(service)


credentials

oauth2client.file

oauth2client.file

oauth2client.file

References I refered to prepare this sample script are as follows.
