Ich habe einige Probleme mit meinem Himbeer-Setup.Keine Verbindung zu Firebase von meinem Raspberry Pi
Der Test:
# -*- coding: utf-8 -*-
import requests
import json
firebase_url = 'https://myDb.firebaseio.com'
name = 'db_name'
test = {}
print(firebase_url + '/' + name + '/setup.json')
test = requests.get(firebase_url + '/' + name + '/setup.json')
test = test.json()
print(test)
Läuft auf meinem Laptop ohne Probleme. Auf dem Raspberry Pi bekomme ich das:
https://myDb.firebaseio.com/db_name/setup.json

Ich bekomme, dass es bedeutet, dass es nicht verbinden kann. Warum es keine Verbindung herstellen kann, ist eine andere Frage. Ich führe diesen Test aus, während ich über SSH mit weaved angemeldet bin. So läuft das Internet ohne Probleme. Ich habe das Gefühl, dass mir etwas offensichtlich fehlt, aber ich weiß einfach nicht, wo ich hinschauen soll.
Danke!
