而服务器输出如下所示:
每次我我试图通过websocket发送东西在浏览器中,服务器只是打印CONNECT,但没有显示js控制台的日志。
编辑:我已经在浏览器中使用echo.websocket.org测试了Websockets,并按预期得到了答案:

I'm following the instructions in the documentation site, but I got stuck in the echo example, the websocket is created correctly and it's connected to the server but when I send anything to the server I'm not getting any response (In the example says I should see an alert window with the same message that I send into the socket but I don't, although I've changed the alert for a console.log but still), what I'm doing wrong?
In settings.py:
INSTALLED_APPS = {
...
'channels',
'myapp',
...
}
...
# Channels settings
CHANNEL_LAYERS = {
"default": {
"BACKEND": "asgiref.inmemory.ChannelLayer",
"ROUTING": "myapp.routing.channel_routing",
},
}
In routing.py:
from channels.routing import route
from myapp.consumers import *
channel_routing = [
route("websocket.receive", ws_receive),
]
In consumers.py:
def ws_receive(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'],
})
In asgi.py
import os
from channels.asgi import get_channel_layer
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myapp.settings")
channel_layer = get_channel_layer()
Then I run: python manage.py runserver, and in my browser I go to the server url and in the console I put the following:
socket = new WebSocket("ws://" + window.location.host + "/chat/");
socket.onmessage = function(e) {
alert(e.data);
}
socket.onopen = function() {
socket.send("hello world");
}
Again, at this point I should see an alert window (or the console.log message) but I get nothing.
The requests that I made have a status of pending (Although I read here and the first comment says it's normal)
And the server output looks like this:
Every time that I've tried to send something through the websocket in the browser, the server just print CONNECT but no log from the js console is showing.
Edit: I've tested websockets in my browser against echo.websocket.org and I got the answer as expected:
I changed to an older version of twisted and it fixed it. Hth
