正在将Django API放入Kubernetes中。

任何发送到/ Controller 的ingress-nginx的流量都会发送到React FE。发送到/api的所有流量都会发送到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: /$1 
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:

从django.contrib导入管理员
从django.urls导入包括路径

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

client部分可以正常工作。 minikube IP是 192.168.99.105。导航到该IP会加载react前端。

导航到 192.168.99.105/api/auth/test/，将我带到“Hello World!”回应我迅速整理。

但是，当我尝试转到 192.168.99.105/api/admin时。如果删除了 /admin/login/?next=/admin/，它会自动将我重定向到不存在的 /api。 是否有防止这种行为的方法？

我也尝试过这个:

ingress-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), 
] 

只是产生“未找到”。

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), 
    ])), 
] 

但这只是使它成为 /api/api。

以下是在 admin/中为 site-packages/django/contrib/admin/sites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剥离URL上的 /api的原因，而只是 192.168.99.105/admin而不是 192.168.99.105/api/admin。

请您参考如下方法:

好的，终于明白了。绝对是Django设置。将以下内容添加到Django settings.py中:

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 Assets :

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就是添加 FORCE_SCRIPT_NAME和更新 STATIC_URL:
