虽然我已经能够将JSON数据发送到Firebase，但是子值的编号范围是0-9（我的JSON有10条新闻文章）。 Here's the JSON output in Firebase
JSON文件每15分钟更新一次最新消息，以替换此JSON中的内容（仅包含10条最新文章）。每当我将最新的JSON发送到Firebase时，当我想添加更多文章时，它将替换以前的0-9值。
为了防止替换这些值，我想将子值设置为JSON中该文章的“ url”。而不是显示为0、1、2、3等，而是将其列为相应的文章网址。
这是我的将JSON上传到Firebase的代码：
with open ('/var/www/mywebsite.com/html/private/scripts/data.json') as data_file:
data=json.load(data_file)
jsondata = json.dumps('/var/www/mywebsite.com/html/private/scripts/data.json')
cred = credentials.Certificate('/var/www/mywebsite.com/html/private/scripts/firebase-adminsdk.json')
firebase_admin.initialize_app(cred, {
'databaseURL': 'https://myapp.firebaseio.com/'
})
ref = db.reference('Feed')
ref.set(data)
我将如何去做？我是Python和Firebase的新手，请原谅我对某些问题的措辞。
