问题描述
我是python的新手.我想在Firebase数据库上实现侦听器.当我在数据库上更改一个或多个参数时,我的Python代码必须执行某些操作.我该怎么做?非常感谢
Hi there I'm new in python.I would like to implement the listener on my Firebase DB.When I change one or more parameters on the DB my Python code have to do something.How can I do it?Thank a lot
我的数据库就像是从001到200的简单数据列表:
my db is like simple list of data from 001 to 200:
"remote-controller"
001 -> 000
002 -> 020
003 -> 230
我的代码是:
from firebase import firebase
firebase = firebase.FirebaseApplication('https://remote-controller.firebaseio.com/', None)
result = firebase.get('003', None)
print result
推荐答案
(2018年10月)似乎已支持此方法:尽管未在检索数据"指南,您可以在 API参考.我对其进行了测试,其工作方式如下:
It looks like this is supported now (october 2018): although it's not documented in the 'Retrieving Data' guide, you can find the needed functionality in the API reference. I tested it and it works like this:
def listener(event):
print(event.event_type) # can be 'put' or 'patch'
print(event.path) # relative to the reference, it seems
print(event.data) # new data at /reference/event.path. None if deleted
firebase_admin.db.reference('my/data/path').listen(listener)
