我如何在Django-Channels中嵌套URLRouter

Question

我尝试使用django.urls.path和django.urls.include来构造 django-channels 路由中的URL。

例如：

from django.urls import path, include

from .browser import routing as browser_routing


websocket_urlpatterns = [
    path('ws/v2/', include([
        path('browser/', browser_routing.urls),
    ])),
]

from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter, URLRouter
from my_channels import routing

application = ProtocolTypeRouter({
    'websocket': AuthMiddlewareStack(
        URLRouter(
            routing.websocket_urlpatterns,
        ),
    ),
})

但是我得到了：

  

django.core.exceptions.ImproperlyConfigured：：URLRouter不支持include（）。采用   嵌套的URLRouter实例。

我在文档中找到了注释，但没有示例： https://channels.readthedocs.io/en/latest/releases/2.1.0.html?highlight=URLRouter#nested-url-routing

Answer 1

我没有使用include，而是通过嵌套URLRouter来解决它。

假设browser_routing.urls也是一组嵌套的URLRouter。

urls.py

from channels.routing import URLRouter

websocket_urlpatterns = URLRouter([
    path('ws/v2/', URLRouter([
        path('browser/', browser_routing.urls),
    ])),
])

routing.py

application = ProtocolTypeRouter({
    'websocket': AuthMiddlewareStack(
        routing.websocket_urlpatterns,
    ),
})
