Question

我的覆盆子设置有些问题。

测试：

# -*- 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)

在我的笔记本电脑上运行没有问题。在Raspberry Pi上，我得到了这个：

https://myDb.firebaseio.com/db_name/setup.json

我知道这意味着它无法连接。为什么它无法连接是另一个问题。我在使用weaved通过SSH登录时运行此测试。因此，互联网正常运行，没有任何问题。我觉得我错过了一些明显的东西，但我只是不知道在哪里看。

谢谢！
