django-channels - 我如何在 Django-Channels 中嵌套 URLRouter

Question

我曾尝试使用 django.urls.path和 django.urls.include在 django-channels 的路由中构建 URL。

前任:

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,
        ),
    ),
})

但我得到:

django.core.exceptions.ImproperlyConfigured: : include() is not supported in URLRouter. Use nested URLRouter instances instead.

我在文档中找到了评论，但没有示例:

Answer 1

而不是使用 include ，我可以通过嵌套来修复它 URLRouter .

假设 browser_routing.urls也是一组嵌套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,
    ),
})
