将Django OAuth2提供程序与JupyterHub一起使用

jupyter docker-compose oauth django python

  • scnerd  · 技术社区  · 8 年前

    我正在尝试运行一个Django web应用程序,该应用程序与JupyterHub服务器配对,用户通过web应用程序进入,然后在登录后被授予访问笔记本服务器的权限。为了实现这一点,我尝试使用OAuth2,Django在其中提供身份验证,JupyterHub根据身份验证来验证用户。

    我正在使用 django-oauth-toolkit 提供身份验证服务,并使用通用OAuthenticator对其进行链接。 A docker-compose reference implementation is available here . 目前,authorize重定向可以工作,但令牌检索过程的某些部分会引发以下错误:

    所有必要的代码和配置都可以通过上面的源链接获得。我是否使用/配置了错误的身份验证?我是否遇到了底层库中的一个bug(我特别怀疑JupyterHub,因为它处于早期的活跃开发阶段)?

    编辑:我已将此发布为 an issue on the OAuthenticator github ,我仍然没有得到任何帮助。我以前找不到其他人将这两个服务连接起来,但它们共享OAuth2协议,因此应该相互协作。我已经深入研究了JupyterHub通用OAuthenticator和Django OAuth2提供程序的源代码,不知道为什么会抛出这个错误。有人能帮我弄清楚吗?

    结果是我必须解决一些小错误才能使其正常工作:

    1. 用于获取令牌的URL相对于JupyterHub服务器,而不像授权URL那样相对于客户端/浏览器。在提供的Docker Compose示例中,django身份验证服务器相对于客户端为“localhost:8000”,但相对于JupyterHub服务器为“django:8000”。
    2. 因此,适当的主机名(“localhost”和“django”)需要位于django应用程序的ALLOWED\u HOSTS列表中。

    3. 我不认为这是必要的,但我还添加了 oauth-toolkit documentation :

      中间件=[ ..., 'oauth2\u提供程序。中间件。OAuth2TokenMiddleware', ]

    4. JupyterHub还需要userdata URL来获取用户名。这必须在OAUTH2\u USERDATA\u URL环境变量中提供(同样,使用相对于JupyterHub服务器的URL),并且该URL必须返回一个JSON blob,其中至少包含一个“username”键。

    从前面的代码到工作示例的完整差异是可用的 at this commit (以及该存储库中的一个完整、最少的示例)。
