Question

消费者档案

def ws_message(message):
    # ASGI WebSocket packet-received and send-packet message types
    # both have a "text" key for their textual data.
    message.reply_channel.send({
        "text": message.content['text'],
    })

路由文件

from channels.routing import route
from myapp.consumers import ws_message

channel_routing = [
    route("websocket.receive", ws_message),
]

我正在跑步。

socket = new WebSocket("ws://" + window.location.host + "/chat/");
socket.onmessage = function(e) {
    alert(e.data);
}
socket.onopen = function() {
    socket.send("hello world");

if (socket.readyState == WebSocket.OPEN) socket.onopen();

它什么都不做。我已经看到过这样的其他问题，他们都说降级到16.2。好吧，我做到了，但然后runserver开始让我无法导入IProtocol ---问题。有没有解决这个问题，或者我应该不使用频道，并尝试别的吗？

在consumers.py文件中添加以下方法......

@channel_session_user_from_http
def ws_connect(message):


    message.reply_channel.send({"accept": True})
    room = message.content['path'].strip("/")
    message.channel_session['room'] = room
    Group("chat-%s" % room).add(message.reply_channel)

@channel_session
def ws_message(message):
Group("chat-%s" % message.channel_session['room']).send(content={
            'text': json.dumps({
                'message': message.content['text'],
                'data': hi,
            # "text": message['text'],
            # "text": str(serializers.data),
            })  })

@channel_session_user
def ws_disconnect(message):
    Group("chat-%s" % message.channel_session['room']).discard(message.reply_channel)

Django频道; ECHO的例子不起作用
