Question

我正在开发第一款使用Google Api for Calendar的应用程序。我在以下网址阅读了Google示例：https://developers.google.com/google-apps/calendar/instantiate

我第一次运行下面的程序是成功的。我允许我的应用访问我的Google帐户，应用程序在我的app-directory中创建了一个带有auth信息的calendar.dat文件。在我重命名该文件后，代码在auth停止工作。我已经完全删除了文件并从头开始重新创建，但错误仍然存在。

我仍然可以获得Google身份验证页面，但仍然可以确认访问权限，之后我收到一条消息，说明身份验证流程已完成。

这是代码（我用我的应用详情填写的标准Google示例）：

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')

这是输出：

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

问题是在您的运行目录中有一个名为calendar.py的文件。当Google的httplib2想要导入标准日历模块时，它会获得本地日历模块。在本地，它执行它来执行导入。但由于httplib2尚未完全导入，因此calendar.py代码无法正常工作。只需将calendar.py重命名为myCalendar.py。
