django - 使用 pyfcm 时出现导入错误

Question

安装 pyfcm 使用：pip install pyfcm

 from pyfcm import FCMNotification
ImportError: cannot import name 'FCMNotification'

在 python2.7 和 python3.5 中都出现此导入错误

Answer 1

经过多次尝试，我通过重新启动系统解决了这个错误。

这是我的工作代码，当 fire-base database 中的值更改时触发通知。

from pyfcm import FCMNotification
import pyrebase

push_service = FCMNotification(api_key="type server key here")
registration_id = "get this token from your app"
message_title = "Fire Alert"
message_body = "Fire Breakage dehradun"

config = {
"apiKey": "",
"authDomain": "",
"databaseURL": "",
"projectId": "",
"storageBucket": "",
"messagingSenderId": ""
};

firebase = pyrebase.initialize_app(config)
db = firebase.database()
def stream_handler(post):
    print(post)
    if (post['data'] is 1):
        result = push_service.notify_single_device(registration_id=registration_id, message_title=message_title, message_body=message_body)
        print (result)
my_stream = db.child("fire_sensor_status").stream(stream_handler, None)

希望这会帮助你:)
