Websocket 群聊功能

websocket 群聊

前提关闭防火墙

写入代码

from flask import Flask,request,render_template

from geventwebsocket.handler import WebSocketHandler

from gevent.pywsgi import WSGIServer

from geventwebsocket.websocket import WebSocket

app = Flask(__name__)

user_socket_list=[]

@app.route("/conn_ws")

def ws_app():

    # print(request.environ)

    """

    wsgi.websocket:<geventwebsocket.websocket.WebSocket object at 0x0000000003Bc8528>

    :return:

    """

    user_socket = request.environ.get("wsgi.websocket")

    user_socket_list.append(user_socket)

    while True:

        msg =user_socket.receive()

        print(msg)

        for usocket in user_socket_list:

            usocket.send(msg)

            #user_socket.send(msg)

    #1 已经开启的websocket连接

    #3 开启了websocket连接 然后 断开了

    # return "123"

@app.route("/")

def index():

    return  render_template("my_ws.html")

if __name__ =="__main__":

    http_serv = WSGIServer(("0.0.0.0",9527),app,handler_class=WebSocketHandler)

    http_serv.serve_forever()

ws_serv

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>Title</title>

</head>

<body>

<input type="text" id="send_str">

<button id="send_btn" onclick="send()"> 发送消息</button>

<p>

<div id="chat_list">

</div>

</p>

</body>

<script type="application/javascript">

    var ws=new WebSocket("ws://192.168.11.78:9527/conn_ws");   // 自己的ip地址,页面才往自己页面显示内容

    ws.onmessage =function (messageEvent) {

        console.log(messageEvent.data);

        var ptag = document.createElement("p");

        ptag.innerText =messageEvent.data;

        document.getElementById("chat_list").appendChild(ptag);

    };

    function send() {

        var send_str = document.getElementById("send_str").value;

        ws.send(send_str);

    }

</script>

</html>

my_ws.html
