我正在使用 django 通道教程，并且我执行了教程中的任何操作，当我单击消息的发送按钮时，我从终端收到错误： “获取/ws/聊天/大厅/ HTTP/1.1”404 2232
我的routing.py文件：
from django.urls import re_path
from .consumers import ChatConsumer
websocket_urlpatterns = \[
re_path('ws/chat/\<room_name\>', ChatConsumer.as_asgi()),
\]
我的消费者.py：
import json
from channels.generic.websocket import WebsocketConsumer
class ChatConsumer(WebsocketConsumer):
def connect(self):
self.accept()
def disconnect(self, close_code):
pass
def receive(self, text_data):
text_data_dict = json.loads(text_data)
message = text_data_dict['message']
self.send(text_data=json.dumps({
'message': message
}))
views.py：
from django.shortcuts import render
def index(request):
return render(request, "chat/index.html")
def room(request, room_name):
context = {
"room_name": room_name
}
return render(request, 'chat/room.html', context)
urls.py：
from django.urls import path
from .views import index, room
urlpatterns = [
path('', index, name='index'),
path('<str:room_name>/', room, name='room')
]
asgi.py 文件：
import os
from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter, URLRouter
from django.core.asgi import get_asgi_application
import Chat.routing
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")
application = ProtocolTypeRouter({
"http": get_asgi_application(),
"websocket": AuthMiddlewareStack(
URLRouter(
Chat.routing.websocket_urlpatterns
)
),
})
和我的 room.html 文件：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<title>Chat Room</title>
</head>
<body>
<textarea id="chat-log" cols="100" rows="20"></textarea><br>
<input id="chat-message-input" type="text" size="100"><br>
<input id="chat-message-submit" type="button" value="Send">
{{ room_name|json_script:"room-name" }}
<script>
const roomName = JSON.parse(document.getElementById('room-name').textContent);
const chatSocket = new WebSocket(
'ws://'
+ window.location.host
+ '/ws/chat/'
+ roomName
+ '/'
);
chatSocket.onmessage = function(e) {
const data = JSON.parse(e.data);
document.querySelector('#chat-log').value += (data.message + '\n');
};
chatSocket.onclose = function(e) {
console.error('Chat socket closed unexpectedly');
};
document.querySelector('#chat-message-input').focus();
document.querySelector('#chat-message-input').onkeyup = function(e) {
if (e.keyCode === 13) { // enter, return
document.querySelector('#chat-message-submit').click();
}
};
document.querySelector('#chat-message-submit').onclick = function(e) {
const messageInputDom = document.querySelector('#chat-message-input');
const message = messageInputDom.value;
chatSocket.send(JSON.stringify({
'message': message
}));
messageInputDom.value = '';
};
</script>
</body>
</html>
如何解决这个问题？
我尝试了
python manage.py runserverNot Found: /ws/chat/lobby/
[11/Nov/2022 11:15:36] "GET /ws/chat/lobby/ HTTP/1.1" 404 2232
我遇到了类似的问题，就我而言，事实是请求没有由异步工作人员处理。我用以下方法修复了它：
pip install channels[daphne]然后将
daphneINSTALLED_APPSchannelsINSTALLED_APPS = [
"daphne",
"django.contrib.admin",
"django.contrib.auth",
"django.contrib.contenttypes",
"django.contrib.sessions",
"django.contrib.messages",
"django.contrib.staticfiles",
"chat.apps.ChatConfig",
]
Daphne 控制了
runserverchannels
