python - 如何在 Tornado 中使用 OpenID 进行身份验证？

问题描述

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 Tornado 的新手，我设法使用 Node.js 的 Passport 包（首先在 Node.js 上进行测试）来工作，我能够id_token在回调中得到它。

我正在使用OAuth2Mixinfromtornado.auth来授权使用用户凭据授予的访问权限，然后在重定向时，我正在获取 from codeget 参数。我不知道如何从那里继续：D

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。

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

class SuccessLoginHandler(BaseHandler, OpenIdMixin, OAuth2Mixin):
  async def get(self):
    code = self.get_argument('code', None)
    if code is not None:
      return self.write(code)

    self.write('no code')

我期待id_token后面；这是一个智威汤逊。我可以对其进行解码并获取所需的数据。

更新： 如果需要配置。

解决方案

您需要调用get_authenticated_userfromSuccessLoginHandler以获取访问令牌。

但是，我宁愿在单个处理程序中编写所有内容，以保持代码更短且不重复。你可以这样重写LoginHandler：

class LoginHandler(BaseHandler, OAuth2Mixin, OpenIdMixin):

    _OAUTH_AUTHORIZE_URL = 'https://authserver.io/uas/oauth2/authorization'
    _OAUTH_ACCESS_TOKEN_URL = 'https://authserver.io/uas/oauth2/token'

    async def get(self):
        redirect_uri = 'http://localhost:3001/login'

        code = self.get_argument('code', None)

        if code:
            # if there's `code`, get access token
            user = await self.get_authenticated_user()

            # the `user` variable now contains the returned data
            # from the oauth server.
            # you'll probably want to `set_secure_cookie`
            # or do something else to save the user

            # then redirect the user to some page
            self.redirect("/") # redirects to home page
            return 

        else:
            # otherwise get authorization `code`       
            self.authorize_redirect(
                redirect_uri=redirec_uri,
                client_id='abcd',
                client_secret='1234',
            )
