如何在Tornado中使用OpenID进行身份验证？

Question

我将Tornado web服务器用于一个简单的web应用程序，并希望使用OpenID对用户进行身份验证。我是龙卷风的新手，我设法用节点.js'护照包（正在测试节点.js首先），我可以在回调中得到id_token。在

我使用OAuth2Mixinfromtornado.auth使用用户凭证授权访问，然后在重定向时，我得到fromcodeget参数。我不知道怎么继续下去

from tornado.auth import OpenIdMixin, OAuth2Mixin
from .base import BaseHandler

class LoginHandler(BaseHandler, OAuth2Mixin, OpenIdMixin):
  def get(self):
    self._OAUTH_AUTHORIZE_URL = 'https://authserver.io/uas/oauth2/authorization'
    self._OAUTH_ACCESS_TOKEN_URL = 'https://authserver.io/uas/oauth2/token'
    self.authorize_redirect(
      redirect_uri='http://localhost:3001/success-login',
      client_id='abcd',
      client_secret='1234',
    )

然后在另一个处理程序上。在

^{pr2}$

我希望id_token回来；这是一个JWT。我可以解码并得到所需的数据。在

更新： 以防需要配置。在

最后我使用Tornado的httpclient将请求发送到OpenID服务器。在

import base64
import urllib.parse
import json
import tornado.httpclient

from .base import BaseHandler
from settings import OID_AUTH_API, OID_REDIRECT_URI, OID_CLIENT_ID, OID_CLIENT_PASSWORD
from lib import logger

class LoginHandler(BaseHandler):
    _redirect_uri = urllib.parse.quote(OID_REDIRECT_URI, safe='')
    _scope = 'openid+profile+email'
    _response_type = 'code'
    _http_client = tornado.httpclient.AsyncHTTPClient()

    async def get(self):
        try:
            code = self.get_argument('code', None)

            if (code is None):
                self.redirect('%s/authorization?client_id=%s&scope=%s&response_type=%s&redirect_uri=%s' % (
                    OID_AUTH_API, OID_CLIENT_ID, self._scope, self._response_type, self._redirect_uri), self.request.uri)
                return

            # exchange the authorization code with the access token
            grant_type = 'authorization_code'
            redirect_uri = self._redirect_uri
            authorization_header = '%s:%s' % (
                OID_CLIENT_ID, OID_CLIENT_PASSWORD)
            authorization_header_encoded = base64.b64encode(
                authorization_header.encode('UTF-8')).decode('UTF-8')
            url = '%s/token?grant_type=%s&code=%s&redirect_uri=%s' % (
                OID_AUTH_API, grant_type, code, redirect_uri)
            token_exchange_response = await self._http_client.fetch(
                url,
                method='POST',
                headers={
                    'Content-Type': 'application/x-www-form-urlencoded',
                    'Authorization': 'Basic %s' % authorization_header_encoded,
                    'Accept': 'application/json'
                },
                body='')

            token_exchange_response_body_dict = json.loads(
                token_exchange_response.body)

            access_token = token_exchange_response_body_dict.get(
                'access_token')

            self.send_response({
                'access_token': access_token
            })
        except tornado.httpclient.HTTPClientError as error:
            logger.log_error(error.response.body.decode('UTF-8'))

            self.send_response({
                'success': False,
                'message': 'Error occurred while trying to obtain the access token'
            }, 500)
        except Exception as error:
            logger.log_error_with_traceback(error)
            self.send_response({
                'success': False,
                'message': 'Internal server error. Please try again later.'
            }, 500)
