如何防止 Django 将管理 URI 覆盖为 /admin 而不是 /api/admin/

Question

正在努力将 Django API 放入 Kubernetes。

发送到 / 的任何流量，ingress-nginx 控制器发送到 React FE。任何发送到 /api 的流量都会发送到 Django BE。

这是ingress-serivce.yaml的相关部分：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-service
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/rewrite-target: /
spec:
  rules:
    - http:
        paths:
          - path: /?(.*)
            backend:
              serviceName: client-cluster-ip-service
              servicePort: 3000
          - path: /api/?(.*)
            backend:
              serviceName: server-cluster-ip-service
              servicePort: 5000

这是url.py:

来自 django.contrib 导入管理员来自 django.urls 导入包含，路径

urlpatterns = [
    path('auth/', include('authentication.urls'), name='auth'),
    path('admin/', admin.site.urls, name='admin'),
]

client 部分工作得很好。 minikube IP 是 192.168.99.105。导航到该 IP 会加载反应前端。

导航到 192.168.99.105/api/auth/test/ 将我带到一个 `"Hello World!" 响应，我很快就把它们放在一起了。

然而，当我试图去192.168.99.105/api/admin。它会自动将我重定向到 /admin/login/?next=/admin/，鉴于 /api 正在被删除，它不存在。 有什么办法可以防止这种行为吗？

我也刚试过这个：

入口-service.yaml

- http:
    paths:
      - path: /?(.*)
        backend:
          serviceName: client-cluster-ip-service
          servicePort: 3000
      - path: /api/?(.*)
        backend:
          serviceName: server-cluster-ip-service
          servicePort: 5000
      - path: /admin/?(.*)
        backend:
          serviceName: server-cluster-ip-service
          servicePort: 5000

urls.py

urlpatterns = [
    path('auth/', include('authentication.urls'), name='auth'),
    path('/', admin.site.urls),
]

这只会产生 "Not Found"。

我也尝试使用 the documentation 中显示的这种模式作为前缀：

urlpatterns = [
    path('api/', include([
        path('auth/', include('authentication.urls'), name='auth'),
        path('admin/', admin.site.urls),
    ])),
]

但这只是 /api/api。

这是在 site-packages/django/contrib/admin/sites 中为 admin/ 定义的路由：

# Admin-site-wide views.
urlpatterns = [
    path('', wrap(self.index), name='index'),
    path('login/', self.login, name='login'),
    path('logout/', wrap(self.logout), name='logout'),
    path('password_change/', wrap(self.password_change, cacheable=True), name='password_change'),
    path(
        'password_change/done/',
        wrap(self.password_change_done, cacheable=True),
        name='password_change_done',
    ),
    path('jsi18n/', wrap(self.i18n_javascript, cacheable=True), name='jsi18n'),
    path(
        'r/<int:content_type_id>/<path:object_id>/',
        wrap(contenttype_views.shortcut),
        name='view_on_site',
    ),
]

我猜 '' 是导致 Django 从 URL 中剥离 /api 并使其成为 192.168.99.105/admin 而不是 192.168.99.105/api/admin 的原因。

好吧，终于想通了。绝对是 Django 设置。将以下内容添加到 Django settings.py:

FORCE_SCRIPT_NAME = '/api/'

然后我不得不更新 STATIC_URL 因为它不再为管理门户提供资产：

STATIC_URL = '/api/static/`

我正在使用的完整 settings.py，但实际上唯一需要更改的是添加 FORCE_SCRIPT_NAME 和更新 STATIC_URL:

Django settings for config project.
