一个项目的 Django 多重身份验证后端 [英] Django Multiple Authentication Backend for one project

问题描述

我有一个用 Django 编写的应用程序，我必须扩展它并包含一些其他解决方案作为应用程序"；在这个应用程序中.

I have an application written in Django and I have to extend it and include some other solution as an "app" in this application.

例如，我要集成的应用名为my_new_app"；现在有一个为主应用编写的后端认证，我无法使用它.

For example, my app to be integrated is named "my_new_app" Now there is a backend authentication written for the main application and I cannot use it.

我有一个 MySQL 数据库可供查询，主应用程序主要使用 Cassandra 和 Redis.

I have a MySQL DB to query from and the main app uses Cassandra and Redis mostly.

有什么办法可以为新应用程序my_new_app"使用单独的身份验证后端?并在同一个域中运行?

Is there any way I can use a separate authentication backend for the new app "my_new_app" and run both in the same domain?

推荐答案

您可以有多个身份验证后端.只需在 Django 项目的 settings.py 中设置 AUTHENTICATION_BACKENDS 即可列出要使用的后端实现.例如，我经常使用 OpenID 身份验证和标准 Django 身份验证的组合，例如在我的 settings.py 中:

You can have multiple authentication backends. Just set the AUTHENTICATION_BACKENDS in settings.py of your Django project to list the backend implementations you want to use. For example I often use a combination of OpenID authentication and the standard Django authentication, like this in my settings.py:

AUTHENTICATION_BACKENDS = (
    'django.contrib.auth.backends.ModelBackend',
    'django_openid_auth.auth.OpenIDBackend',
    )

在此示例中，Django 将首先尝试使用 django.contrib.auth.backends.ModelBackend 进行身份验证，这是 Django 的默认后端.如果失败，那么它移动到下一个后端，django_openid_auth.auth.OpenIDBackend.

In this example Django will first try to authenticate using django.contrib.auth.backends.ModelBackend, which is the default backend of Django. If that fails, then it moves on to the next backend, django_openid_auth.auth.OpenIDBackend.

请注意，您的自定义后端必须位于 Django 可见的路径上.在此示例中，我必须将 django_openid_auth 添加到 INSTALLED_APPS，否则 Django 将无法导入它并将其用作后端.

Note that your custom backends must be at a path visible by Django. In this example I have to add django_openid_auth to INSTALLED_APPS, otherwise Django won't be able to import it and use it as a backend.

还看了相关文档，写的很好，通俗易懂:https://docs.djangoproject.com/en/dev/topics/auth/customizing/

Also read the relevant documentation, it's very nicely written, easy to understand: https://docs.djangoproject.com/en/dev/topics/auth/customizing/
