最近我开始研究Google日历 API，希望为自己制作一个个人应用程序，可以随机生成每天的重点内容，并将其转换为事件后传递给我的 Google 日历。我在这方面几乎没有任何经验，但是谷歌的快速入门指南帮助我了解了一些基本知识。我主要使用了他们提供的 Python 快速入门代码，并添加了一些自己的函数来创建和删除事件，然后调整了范围以包括创建和删除事件所需的权限。
我使用的代码：
from __future__ import print_function
import datetime
from hashlib import new
import os.path
from re import S
from google.auth.transport.requests import Request
from google.oauth2.credentials import Credentials
from google_auth_oauthlib.flow import InstalledAppFlow
from googleapiclient.discovery import build
from googleapiclient.errors import HttpError
from highlightsGenerator import *
# If modifying these scopes, delete the file token.json.
SCOPES = ['https://www.googleapis.com/auth/calendar.readonly',
'https://www.googleapis.com/auth/calendar.events',
'https://www.googleapis.com/auth/calendar']
templateEvent = {
'summary': 'Daily Highlight',
'description': '',
'start': {
'dateTime': '',
},
'end': {
'dateTime': '',
},
'reminders': {
'useDefault': True,
},
}
def createHighlightEvents(service):
workingDate = datetime.date.today()
workingDate += datetime.timedelta(days=1)
highlightSchedule = scheduleGenerator()
print(highlightSchedule)
for k in highlightSchedule:
newEvent = templateEvent
newEvent['description'] = k
newEvent['start']['dateTime'] = str(workingDate) + 'T13:00:00+3:00'
newEvent['end']['dateTime'] = str(workingDate) + 'T17:00:00+03:00'
service.events().insert(calendarId='primary', body=newEvent).execute()
workingDate += datetime.timedelta(days=1)
def deleteHighlightEvents(service):
now = datetime.datetime.utcnow().isoformat() + 'Z' # 'Z' indicates UTC time
events_result = service.events().list(calendarId='primary', q='Daily Highlight',timeMin=now,
maxResults=20, singleEvents=True,
orderBy='startTime').execute()
events = events_result.get('items', [])
# if not events:
# print('No upcoming events found.')
# return
for event in events:
eID = event['id']
service.events().delete(calendarId='primary', eventId=eID).execute()
def reRollHighlightEvents(service):
deleteHighlightEvents(service)
createHighlightEvents(service)
def getDate(dateTime):
dateStr = dateTime[:len(dateTime) - 6]
date = datetime.datetime.strptime(dateStr, '%Y-%m-%dT%H:%M:%S')
return date
def shiftHighlights(service, numDays):
now = datetime.datetime.utcnow().isoformat() + 'Z' # 'Z' indicates UTC time
events_result = service.events().list(calendarId='primary', q='Daily Highlight',timeMin=now,

if not events:
print('No upcoming events found.')
return
for event in events:
newStartDate = getDate(event['start']['dateTime']) + datetime.timedelta(days=numDays)
newEndDate = getDate(event['end']['dateTime']) + datetime.timedelta(days=numDays)
newStartDateStr = 'T'.join([str(newStartDate.date()), str(newStartDate.time())])
newEndDateStr = 'T'.join([str(newEndDate.date()), str(newEndDate.time())])
newEvent = event
newEvent['start']['dateTime'] = newStartDateStr + '+03:00'
newEvent['end']['dateTime'] = newEndDateStr + '+03:00'
service.events().update(calendarId='primary', eventId=event['id'], body=newEvent).execute()
def main():

我设法让它做我想要的事情，一度效果良好，但昨天尝试运行时却因为无效请求而出现了http 400错误。 点击提供的链接后，我看到了这个：
{
"error": {
"code": 403,
"message": "The request is missing a valid API key.",
"errors": [
{
"message": "The request is missing a valid API key.",
"domain": "global",
"reason": "forbidden"
}
],
"status": "PERMISSION_DENIED"
}
}
现在，您可能已经看到了我留下的代码，用于检索和显示前10个即将到来的事件。它仍然能够正常运行，但是如果尝试创建或删除事件，则会出现此错误消息。我对这条消息感到非常困惑，因为我相信我已经完成了所有必要的授权。我的客户端密钥没有更改，但即使如此，我也重新下载了它，以查看是否有任何变化，但没有。我删除了令牌并运行了授权，再次允许授权。这也没有带来任何成果，据我所知，我的范围是正确的。
在这里有一些类似错误的问题，但是它们似乎由于不同的原因而出现（从我能看出来），或者是因为他们缺少一个我认为我已经拥有的授权。
再次说明，我几乎没有这方面的经验，因此可能有一些非常明显的事情我没有做，但是我恐怕不知道那是什么。
如有任何帮助，将不胜感激。
