Question

我从快速启动（https://developers.google.com/google-apps/calendar/quickstart/python）开始，它运作良好。然后我尝试使用本指南插入事件（https://developers.google.com/google-apps/calendar/create-events）。我将此代码添加到quickstart的代码中并出现错误。应该如何看待我的代码在我的谷歌日历中插入事件？

所以这是我的代码：

from __future__ import print_function
import httplib2

from apiclient import discovery
import oauth2client
from oauth2client import client
from oauth2client import tools

import datetime

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

# If modifying these scopes, delete your previously saved credentials
# at ~/.credentials/calendar-python-quickstart.json
SCOPES = 'https://www.googleapis.com/auth/calendar'
CLIENT_SECRET_FILE = 'client_secret.json'
APPLICATION_NAME = 'Google Calendar API Python Quickstart'


def get_credentials():
    """Gets valid user credentials from storage.

    the OAuth2 flow is completed to obtain the new credentials.

    Returns:
        Credentials, the obtained credential.
    """
    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,
                                   'calendar-python-quickstart.json')

    store = oauth2client.file.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():
    """Shows basic usage of the Google Calendar API.

    10 events on the user's calendar.
    """
    credentials = get_credentials()
    http = credentials.authorize(httplib2.Http())
    service = discovery.build('calendar', 'v3', http=http)

    # Refer to the Python quickstart on how to setup the environment:

    # stored credentials.

    event = {
      'summary': 'Google I/O 2015',
      'location': '800 Howard St., San Francisco, CA 94103',
      'description': 'A chance to hear more about Google\'s developer products.',
      'start': {
        'dateTime': '2016-09-28T09:00:00-07:00',

        'useDefault': False,
        'overrides': [

          {'method': 'popup', 'minutes': 10},
        ],
      },
    }

    event = service.events().insert(calendarId='primary', body=event).execute()
    print ('Event created: %s' % (event.get('htmlLink')))

if __name__ == '__main__':
    main()

这是错误的：

    main()

问题出现在文件夹“.credentials”中。在上一次使用

启动quickstart示例后，我没有删除它

SCOPES = 'https://www.googleapis.com/auth/calendar.readonly'

我刚刚删除了这个文件夹和程序。因为现在

SCOPES = 'https://www.googleapis.com/auth/calendar'
