Неверный начальный байт при попытке перенаправить приложение Da sh из Flask

2 голосов
/ 25 марта 2020

Я пытаюсь интегрировать аутентификацию Okta OID C и Da sh в приложение Flask, чтобы пользователь мог просматривать приложение Da sh только после входа в систему с помощью нашей организации. Okta SSO

Попытка: 

from flask import Blueprint, Flask, jsonify, redirect, render_template_string, url_for
from flask_oidc import OpenIDConnect
from okta import UsersClient
import dash

oidc = OpenIDConnect()
okta_client = UsersClient("https://dev-XXXXXX.okta.com",
            "somesecret")

app = Flask(__name__)

app.config.from_mapping(
SECRET_KEY="testkey",
OIDC_CLIENT_SECRETS="/app/appname/client_secrets.json",
OIDC_COOKIE_SECURE= False,
OIDC_CALLBACK_ROUTE="/oidc/callback",
OIDC_SCOPES=["openid", "email", "profile"],
OIDC_ID_TOKEN_COOKIE_NAME="oidc_token",
DEBUG_TB_INTERCEPT_REDIRECTS = False)

oidc.init_app(app)

dash_app.layout = layout.layout
callbacks.register_dash_callbacks(dash_app)
dash_app.run_server(debug=True)

@app.route("/" , methods=["GET"])
@oidc.require_login
def redirect_to_app():
    return redirect(url_for(dash_app.config.requests_pathname_prefix))

дает мне следующее: 

UnicodeDecodeError: 'utf-8' codec can't decode byte 0x8b in position 1: invalid start byte

Приложение прекрасно работает и хорошо интегрируется в приложение Flask. Я пытался исследовать, но не смог найти ничего полезного.

Я также мог бы заставить его работать, разделив его на план, например, так: 

home_blueprint = Blueprint("home", __name__, url_prefix="/")
@home_blueprint.route("/" , methods=["GET"])
@oidc.require_login
def index():
    return redirect(url_for('/dash/'))

Но тогда доступ к приложению напрямую через localhost:5000/dash/ был все еще возможен без авторизации.

Заранее благодарю за помощь.
