我想使用python(firebase_admin)而不是pyrebasepython-firebase的官方库通过Firebase数据库检索一些数据。

我尝试执行以下代码行:

from firebase_admin import db
from firebase_admin import credentials
import firebase_admin

cred = credentials.Certificate('https://project_name.firebaseio.com/.json')
firebase_admin.initialize_app(cred)

result = db.Query.get()


但随后出现以下错误:

FileNotFoundError: [Errno 2] No such file or directory: 'https://project_name.firebaseio.com/.json'


即使当我在浏览器中输入此url(用我的真实项目名称替换project_name)时,我仍从数据库中获取数据的json。

如何解决此错误?

最佳答案

Certificate应指向带有您的凭据/证书的本地文件。相反,您将其指向您的数据库URL(这不是本地文件),因此库将引发错误。

documentation on initializing the Python SDK


import firebase_admin
from firebase_admin import credentials
from firebase_admin import db

# Fetch the service account key JSON file contents
cred = credentials.Certificate('path/to/serviceAccountKey.json')

# Initialize the app with a service account, granting admin privileges
firebase_admin.initialize_app(cred, {
    'databaseURL': 'https://databaseName.firebaseio.com'
})

# As an admin, the app has access to read and write all data, regardless of Security Rules
ref = db.reference('restricted_access/secret_document')
print(ref.get())
