Question

我正在创建 python django web 应用程序来上传 firebase 实时数据库上的数据。我正在使用 python3 和 pyrebase4。 Firebase 身份验证已完成。用户登录和登录程序已完成。我在第三步中遇到了错误，即在实时数据库上上传数据。
显示运行时错误的行是：

db.child('users').child(a).child('reports').child(millis).set(data)

运行时错误是：

HTTPConnectionPool Max retries exceeded with url: /%5B'localId'%5D/reports/1617203893.json 
Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x000001C44758D8E0>: 
Failed to establish a new connection: [Errno 11001] getaddrinfo failed'))

这是我参考的视频： https://www.youtube.com/watch?v=bq0AszeDZf4&list=PLhPDb5zFmGR2VfXiN2y-1V0qdRik7Cc0K&index=4

pyrebase4 HTTPConnectionPool 最大重试次数超过 url。 NewConnectionError 建立新连接失败 getaddrinfo failed
