Question

我正在构建一个每1分钟启动一次的Google云端功能。目的是从我的数据库（firebase）获取数据，并在帖子的日期优于一小时前删除此数据。

我正在考虑制作firebase云功能，并在一小时后使用settimeout功能。不幸的是，这是不可能的。所以我决定使用gcloud的cron功能。

这是我的main.py。

import webapp2
from gcloud import datastore
import firebase_admin
from firebase_admin import credentials
from firebase_admin import db

# Fetch the service account key JSON file contents
cred = credentials.Certificate('key.json')

try:
    # Initialize the app with a service account, granting admin privileges
    firebase_admin.initialize_app(cred, {
        'databaseURL': 'https://#########.firebaseio.com/'
    })
except:
    print('no need for init firebase')
# As an admin, the app has access to read and write all data, regradless of Security Rules
ref = db.reference('/')



class HourCronPage(webapp2.RequestHandler):
    def get(self):
        ref.child("test").delete()


app = webapp2.WSGIApplication([
    ('/timer', HourCronPage),
    ], debug=True)

以下是我从gcloud控制台获得的错误，我不知道如何解决这个问题：

有人有想法吗？

提前多谢你们。

您可能需要在App Engine环境中设置相同的其他依赖项（至少为ssl）：https://google-auth.readthedocs.io/en/latest/user-guide.html#the-app-engine-standard-environment

从Google Cloud yalm python应用程序中检索firebase数据库数据
