使用 Google 日历 API 和 Python 3.7 Google 云函数

Question

我在运行一个 Python 3.7 Google 云函数时遇到了一些问题，它应该列出我的 Google 日历的事件。我正在使用 Google 日历 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 服务帐户作为函数标识，它的键是我在上面的凭据变量中引用的 json credential.json。此 json 文件打包在其根目录下的函数包中（附图片）。此外，我已经直接在 Google 日历应用程序中与服务帐户电子邮件共享了我的日历。

功能部署正常，但测试时发现如下错误：

Answer 1

答案：

构建服务时需要声明 cache_discovery=False 标志。

修复：

假设您 google.appengine 使用

安装

pip install googleappengine

您需要更改：

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

至：

service = build('calendar', 'v3', credentials=credentials, cache_discovery=False)
