python - 将 Okta OIDC 与 Dash 应用程序集成

问题描述

我正在尝试将 Okta OIDC 身份验证和 Dash 集成到 Flask 应用程序中，这样用户只有在使用我们组织的 Okta SSO 登录后才能查看 Dash 应用程序

试：

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))

给了我以下内容：

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

该应用程序运行良好，并且可以很好地集成到 Flask 应用程序中。我试过研究，但找不到任何有用的东西。

我还可以通过将其分成如下蓝图来使其工作：

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

但是，在localhost:5000/dash/未经授权的情况下，仍然可以直接通过该应用程序访问该应用程序。

预先感谢您的帮助。

编辑：这里是完整的追溯：

解决方案

好的，所以我找到了这篇文章，最终通过替换login_required为oidc.require_login. 原来无效的起始字节与我遇到的另一个错误有关。

app = Flask(__name__)


    app.config.from_mapping(
    SECRET_KEY="testkey",
    OIDC_CLIENT_SECRETS="XXX",
    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 = dash.Dash(__name__,
                    server = app,
                    url_base_pathname='/dash/'
                    )


    for view_func in app.view_functions:
        if view_func.startswith(dash_app.config['url_base_pathname']):
            app.view_functions[view_func] = oidc.require_login(app.view_functions[view_func])


    dash_app.layout = html.Div([intro_div, navbar, exec_dashboard, body])
    register_dash_callbacks(dash_app)
