除了Google的代码段以外，还可以创建日历事件？

问题描述

我试图通过Google API调用创建日历事件。根据{{​​3}}，我必须使用：

from __future__ import print_function
import datetime
import pickle
import os.path
from googleapiclient.discovery import build
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request

# If modifying these scopes,delete the file token.pickle.
SCOPES = ['https://www.googleapis.com/auth/calendar.readonly']


def main():
    """Shows basic usage of the Google Calendar API.
    Prints the start and name of the next 10 events on the user's calendar.
    """
    creds = None
    # The file token.pickle stores the user's access and refresh tokens,and is
    # created automatically when the authorization flow completes for the first
    # time.
    if os.path.exists('token.pickle'):
        with open('token.pickle','rb') as token:
            creds = pickle.load(token)
    # If there are no (valid) credentials available,let the user log in.
    if not creds or not creds.valid:
        if creds and creds.expired and creds.refresh_token:
            creds.refresh(Request())
        else:
            flow = InstalledAppFlow.from_client_secrets_file(
                'credentials.json',SCOPES)
            creds = flow.run_local_server(port=0)
        # Save the credentials for the next run
        with open('token.pickle','wb') as token:
            pickle.dump(creds,token)

    service = build('calendar','v3',credentials=creds)

    # Call the Calendar API
    now = datetime.datetime.utcnow().isoformat() + 'Z' # 'Z' indicates UTC time
    print('Getting the upcoming 10 events')
    events_result = service.events().list(calendarId='primary',timeMin=now,maxResults=10,singleEvents=True,orderBy='startTime').execute()
    events = events_result.get('items',[])

    if not events:
        print('No upcoming events found.')
    for event in events:
        start = event['start'].get('dateTime',event['start'].get('date'))
        print(start,event['summary'])


if __name__ == '__main__':
    main()

但是，我正在构建一种Alexa技能，其中在调用handler_input.request_envelope.context.system.user.access_token之后，alexa已经提供了access_token 。因此，我将代码调整为以下形式：

import os
import pickle
os.environ['GOOGLE_APPLICATION_CREDENTIALS'] = 'Timer_Hello_Layered/creds.json'     
SCOPES = ['https://www.googleapis.com/auth/calendar.readonly']

            
event = {
'summary': 'Test','location': 'At home','description': 'A chance to hear more about Google\'s developer products.','start': {
    'dateTime': '2020-07-29T12:12:10','timeZone': 'America/Los_Angeles',},'end': {
    'dateTime': '2020-07-29T12:32:47',}
}
#way of retrieving access token with alexa skill
creds = handler_input.request_envelope.context.system.user.access_token
#have to add /tmp/ when dealing with AWS lambda
SCreds = pickle.dump(creds,open("/tmp/save.pickle","wb")) 
service = build('calendar',credentials= SCreds,cache_discovery=False)    
event = service.events().insert(calendarId='primary',body=event).execute()

我意识到使用此代码，由于未在任何地方传递SCOPES或creds.json文件，因此未创建事件（depsite出现否错误）。但是，与此同时，alexa不允许我运行creds = flow.run_local_server(port=0)。

也有这个document，但我不知道它是否可以解决。即使是，也没有将creds.json传递给的参数。

有什么办法解决吗？ 非常感谢您的帮助，因为我已经在此库存了2个多星期：（（
