问题描述
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'))
