在Django通道上找不到路径

Question

我在Django channels应用程序上创建了一个简单的使用者，但当我尝试从前端连接到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/'.

以下是我的路线： myapp>；路由.py

from .consumers import EchoConsumer

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

mysite>；路由.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
        )
    ),
})

下面是我如何尝试从前端连接到websocket：

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

谁能帮我找出我做错了什么

Answer 1

您使用的是路径而不是url，请在routing.py中尝试以下操作：

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

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