Flask 与用户身份验证的集成

我想使用Plotly的dash framework on flask framework集成创建一个仪表板。我想在flask中添加基于令牌的用户身份验证。成功验证后，dash应用程序连接到烧瓶并显示在浏览器路径上

from flask import Flask, redirect
from dash import Dash
import dash_html_components as html
import dash_core_components as dcc

server = Flask(__name__)

app = Dash(__name__, server=server, url_base_pathname='/dashboard/')

@app.server.route('/')
def index():
    return "hello"

@app.server.route("/dashboard/")
@app_auth  # the authentication decorator 
def layout(data):
    if data['isAuthentication']:
        app.layout = html.Div([html.Div("welcome in dash app")])
        return app.layout

if __name__=="__main__":
    app.server.run()

但这是行不通的
