标签：通过   django   rom   cal   print   result   render   dem   click   

后台代码：

url：：：

url(r‘^echo_cc/(?P<userid>[0-9]+)/(?P<sendid>[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)
