将Google Calendar API与Python 3.7 Google Cloud Function一起使用

Question

我在运行应列出我的Google日历事件的Python 3.7 Google Cloud Function时遇到了一些麻烦。我正在使用Google Calendar API。

这是我的代码。

from googleapiclient import discovery
import datetime
from apiclient.discovery import build
import datetime
from google.oauth2 import service_account

def listEvents(request):
    credentials = service_account.Credentials.from_service_account_file('credential.json',scopes=['https://www.googleapis.com/auth/calendar.readonly'],)
    service = build('calendar', 'v3', credentials=credentials)
    now = datetime.datetime.utcnow().isoformat() + 'Z' # 'Z' indicates UTC time
    return('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:
        return('No upcoming events found.')
    for event in events:
        start = event['start'].get('dateTime', event['start'].get('date'))
        return(start, event['summary'])

我使用App Engine服务帐户作为功能标识，其密钥是我在上面的凭据变量中引用的json credential.json。此json文件打包在功能包的根目录中（附加了图像）。此外，我已经直接在Google Calendar APP中与服务帐户电子邮件共享了日历。

该功能已部署好，但是在测试时发现以下错误：

任何想法都将不胜感激。

干杯，

Answer 1

答案：

cache_discovery=False标志在构建服务时需要声明。

修复：

假设您已使用]安装了google.appengine，>

pip install googleappengine
您需要更改：

service = build('calendar', 'v3', credentials=credentials)
至：

service = build('calendar', 'v3', credentials=credentials, cache_discovery=False)
希望对您有帮助！
