Python 从dev_appserver连接到Firebase时出错：VerifiedHTTPSConnection对象没有属性\u tunnel\u host

我正在本地运行一个服务，我打算将它作为一个服务在GCP中运行。我正在使用服务帐户json文件对Firebase进行身份验证

from firebase_admin import credentials
from firebase_admin import db

cred = credentials.Certificate('./firebase-service-account.json')
firebase_admin.initialize_app(cred, {
    'databaseURL': 'https://XXXXXXXX.firebaseio.com/'
})

。。。 ref.child（msg_id）.set（数据）

但是，当我尝试写入Firebase时，我看到以下错误：

AttributeError: 'VerifiedHTTPSConnection' object has no attribute 
'_tunnel_host'

我将在下面粘贴stacktrace，以防它提供一些额外的清晰度：

这已经在的评论部分得到了回答，但为了更清楚，只需在应用程序初始化的地方添加以下行：

from requests_toolbelt.adapters import appengine
appengine.monkeypatch()

---

就这样。有关更多信息，请参阅。

谢谢，约翰。我刚刚找到了，打算把它贴出来。验证了它的工作原理：）用新代码发布您的解决方案。这会帮助别人的。谢谢你，约翰。我刚刚找到了，打算把它贴出来。验证了它的工作原理：）用新代码发布您的解决方案。这将帮助其他人。
