django-通道:没有找到路径的路由
我有一个Django + Vue.js聊天应用程序，我正在尝试连接到django-通道。
要访问任何聊天室，只需访问：
http://localhost:8080/rooms/"id"/
我的javascript连接如下所示：
connectToWebSocket () {
const chatSocket = new WebSocket(
`ws://localhost:8000/ws/rooms/${this.$route.params.id}/`
)
chatSocket.onopen = this.onOpen
chatSocket.onclose = this.onClose
chatSocket.onmessage = this.onMessage
chatSocket.onerror = this.onError
},我的consumers.py：
class ChatConsumer(WebsocketConsumer):
def connect(self):
self.room_uri = self.scope['url_route']['kwargs']['uri']
self.room_group_name = 'chat_%s' % self.room_uri
# Join room group
async_to_sync(self.channel_layer.group_add)(
self.room_group_name,
self.channel_name
)
self.accept()
def disconnect(self, close_code):
# Leave room group
async_to_sync(self.channel_layer.group_discard)(
self.room_group_name,
self.channel_name
)
# Receive message from WebSocket
def receive(self, text_data):
text_data_json = json.loads(text_data)
message = text_data_json['message']
user = text_data_json['user.username']
# Send message to room group
async_to_sync(self.channel_layer.group_send)(
self.room_group_name,
{
'type': 'chat_message',
'user': user,
'message': message
}
)
# Receive message from room group
def chat_message(self, event):
user = event['user']
message = event['message']
# Send message to WebSocket
self.send(text_data=json.dumps({
'user': user,
'message': message
}))我的routing.py：
from django.conf.urls import url
from core import consumers
websocket_urlpatterns = [
url(r'^ws/rooms/<uri>/', consumers.ChatConsumer),
]我的项目routing.py：
from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter, URLRouter
import core.routing
application = ProtocolTypeRouter({
'websocket': AuthMiddlewareStack(
URLRouter(
core.routing.websocket_urlpatterns
)
)
})问题是，我无法连接到websocket，我的django服务器说：
[故障实例:回溯：：路径‘ws/rooms/759b9a8262e4b7/’找不到路由。
我的代码中有什么问题不能通过websocket连接到特定的房间呢？

如果您需要使用url，我也遇到了同样的问题：
不工作
websocket_urlpatterns = [
path('ws/chat/<str:room_name>/$', consumers.ChatConsumer),
]工作中
websocket_urlpatterns = [
url(r'^ws/chat/(?P<room_name>[^/]+)/$', consumers.ChatConsumer),

我遇到了和你一样的问题，而刚才我碰巧解决了它！在我的ws_client.py里我写了这个
ws.create_connection("ws://127.0.0.1:8000/alarm")在routing.py中，我更改为下面的这个，它起作用了
from django.urls import path
channel_routing = [
path('alarm',consumers.ws_message),
# before I wrote 'alarm/', I just change from alarm/ to alarm
]而且起作用了！你可以试试

试着做这样的事情：
Routing.py(在你的django应用程序中)
from django.urls import path
from core import consumers
websocket_urlpatterns = [
path('ws/rooms/<uri>/', consumers.ChatConsumer),
]Routing.py(与您的settings.py相同的级别)
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
)
),
})最后在你的settings.py中
CHANNEL_LAYERS = {
'default': {
'BACKEND': 'channels_redis.core.RedisChannelLayer',
'CONFIG': {
"hosts": [REDIS_URL],
},
},
}
INSTALLED_APPS.append('channels')
ASGI_APPLICATION = 'myapp.routing.application'https://stackoverflow.com/questions/54107099
