后台代码:

url:::

url(r‘^echo_cc/(?P[0-9]+)/(?P[0-9]+)$‘, views.echo_c, name=‘echo‘)





views代码:::


from django.shortcuts import render
from dwebsocket.decorators import accept_websocket, require_websocket
from django.http import HttpResponse
from collections import defaultdict
# Create your views here.

@require_websocket
def echo_once(request):
message = request.websocket.wait()
request.websocket.send(message)



@accept_websocket
def echo(request):
if not request.is_websocket(): # 判断是不是websocket连接
try: # 如果是普通的http方法



message = request.GET[‘message‘]
return HttpResponse(message)
except:
return render(request, ‘index.html‘)
else:
for message in request.websocket:
print(message)
message = input(‘>>>‘)
request.websocket.send(message) # 发送消息到客户端





allconn = defaultdict(list)#连接池
@accept_websocket
def echo_c(request, userid,sendid):
print(userid,sendid)
allresult = {}
# 获取用户信息
userinfo = request.user
allresult[‘userinfo‘] = userinfo
# 声明全局变量
global allconn
if not request.is_websocket():#判断是不是websocket连接
try:#如果是普通的http方法
message = request.GET[‘message‘]
return HttpResponse(message)
except:
return render(request, ‘myproject/chat.html‘, allresult)
else:
# 将链接(请求?)存入全局字典中
allconn[str(userid)] = request.websocket
# 遍历请求地址中的消息
for message in request.websocket:
# 将信息发至自己的聊天框
# request.websocket.send(message)
# 将信息发至其他所有用户的聊天框
allconn[str(sendid)].send(message)
# for i in allconn:
# if i != str(userid):
# allconn[i].send(message)




html代码::::

html>
    django-websocket
    
    
    $(function () {
        $(‘#connect_websocket‘).click(function () {
            if (window.s) {
                window.s.close()
            }
            /*创建socket连接*/
            var socket = new WebSocket("ws://127.0.0.1:8080/echo_cc/3/2");/* 前面为自己id,后面为发送id*/----------------------------------------------------------------------》》》这里要改一下,这个是个简单demo
            socket.onopen = function () {
                console.log(‘WebSocket open‘);//成功连接上Websocket
            };
            socket.onmessage = function (e) {
                console.log(‘message: ‘ + e.data);//打印出服务端返回过来的数据
                $(‘#messagecontainer‘).prepend(‘

‘ + e.data + ‘

‘);
            };
            // Call onopen directly if socket is already open
            if (socket.readyState == WebSocket.OPEN) socket.onopen();
            window.s = socket;
        });
        $(‘#send_message‘).click(function () {
            //如果未连接到websocket
            if (!window.s) {
                alert("websocket未连接.");
            } else {
                window.s.send($(‘#message‘).val());//通过websocket发送数据
            }
        });
        $(‘#close_websocket‘).click(function () {
            if (window.s) {
                window.s.close();//关闭websocket
                console.log(‘websocket已关闭‘);
            }
        });

    });
