Firebasedata存储和数据检索

Question

尝试使用Python检索数据时出现以下错误。当我要取回它的时候，我得到了下面的stacktrace。还请告诉我如何使用python代码存储这些数据。目前我存储没有代码。你知道吗

我使用的代码是：

from firebase import firebase
firebase = firebase.FirebaseApplication('https://varnika-c226a.firebaseio.com/', None)
result = firebase.get('/varnika-c226a', None)
print result
print firebase

Answer 1

看起来这里有一些错误。上面提到的问题与您无法连接到firebase实例有关，如下所述：

requests.exceptions.ProxyError: HTTPSConnectionPool(host='varnika-c226a.firebaseio.com', port=443): Max retries exceeded with url: /varnika-c226a/.json (Caused by ProxyError('Cannot connect to proxy.', error('Tunnel connection failed: 302 Found',)))

第二个问题是，您似乎不确定如何在firebase中存储数据。这一点很重要，因为在result = firebase.get('/varnika-c226a', None)中检索数据时，无法确定数据是否在'/varnika-c226a'。你知道吗

希望这有帮助！你知道吗
