Google Api for Calendar を使用する初めてのアプリに取り組んでいます。https://developers.google.com/google-apps/calendar/instantiateで Google の例を読みました。
以下のプログラムを初めて実行したときは成功しました。アプリに Google アカウントへのアクセスを許可すると、アプリケーションはアプリ ディレクトリに認証情報を含む calendar.dat ファイルを作成しました。ファイルの名前を変更した後、認証にあったコードが機能しなくなりました。ファイルを完全に削除し、最初から再作成しましたが、エラーは解決しません。
Google 認証ページが表示され、アクセスを確認できます。その後、認証フローが完了したというメッセージが表示されます。
これはコードです (アプリの詳細を入力する標準的な Google の例):
import gflags
import httplib2
from apiclient.discovery import build
from oauth2client.file import Storage
from oauth2client.client import OAuth2WebServerFlow
from oauth2client.tools import run
FLAGS = gflags.FLAGS
# Set up a Flow object to be used if we need to authenticate. This
# sample uses OAuth 2.0, and we set up the OAuth2WebServerFlow with
# the information it needs to authenticate. Note that it is called
# the Web Server Flow, but it can also handle the flow for native
# applications
# The client_id and client_secret are copied from the API Access tab on
# the Google APIs Console
FLOW = OAuth2WebServerFlow(
client_id='YOUR_CLIENT_ID',
client_secret='YOUR_CLIENT_SECRET',
scope='https://www.googleapis.com/auth/calendar',
user_agent='YOUR_APPLICATION_NAME/YOUR_APPLICATION_VERSION')
# To disable the local server feature, uncomment the following line:
# FLAGS.auth_local_webserver = False
# If the Credentials don't exist or are invalid, run through the native client
# flow. The Storage object will ensure that if successful the good
# Credentials will get written back to a file.
storage = Storage('calendar.dat')
credentials = storage.get()
if credentials is None or credentials.invalid == True:
credentials = run(FLOW, storage)
# Create an httplib2.Http object to handle our HTTP requests and authorize it
# with our good Credentials.
http = httplib2.Http()
http = credentials.authorize(http)
# Build a service object for interacting with the API. Visit
# the Google APIs Console
# to get a developerKey for your own application.
service = build(serviceName='calendar', version='v3', http=http,
developerKey='YOUR_DEVELOPER_KEY')
そして、これは出力です:
Your browser has been opened to visit:
https://accounts.google.com/o/oauth2/auth? (auth url shortened)
If your browser is on a different machine then exit and re-run this
application with the command-line parameter
--noauth_local_webserver
