python - 在 Django Channels 上找不到路径

Question

我在我的 Django channel 应用程序上创建了一个简单的消费者，但是当我尝试从我的前端连接到 websocket 时，我不断收到以下错误:

ws_protocol: ERROR - [Failure instance: Traceback: <class 'ValueError'>: No route found for path 'messages/127.0.0.1:8000/messages/'.

这是我的路线:myapp>routing.py

from .consumers import EchoConsumer

websocket_urlpatterns = [
    path("messages/", EchoConsumer),
]

mysite>routing.py

# mysite/routing.py
from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter, URLRouter
import myapp.routing

application = ProtocolTypeRouter({
    # (http->django views is added by default)
    'websocket': AuthMiddlewareStack(
        URLRouter(
            myapp.routing.websocket_urlpatterns
        )
    ),
})

这是我尝试从我的前端连接到 websocket 的方式:

var wsStart = 'ws://' + window.location.host + window.location.pathname

谁能帮我找出我做错了什么，好吗？

您正在使用路径而不是 url，只需在 routing.py 中尝试:

from .consumers import EchoConsumer
from django.conf.urls import url

websocket_urlpatterns = [
    url("messages/", EchoConsumer),
]
