内容简介：1.下载必须的包 https://github.com/Pithikos/python-websocket-server，解压缩并把文件夹名‘python-websocket-server-master’ 改为‘websocket’2.websocket文件夹内只保留websocket_server文件夹和server.py
1.下载必须的包 https://github.com/Pithikos/python-websocket-server，解压缩并把文件夹名‘python-websocket-server-master’ 改为‘websocket’
2.websocket文件夹内只保留websocket_server文件夹和server.py
3.稍微修改server.py的源码
1 from websocket_server import WebsocketServer
2
3 # Called for every client connecting (after handshake)
4 def new_client(client, server):
5 print("New client connected and was given id %d" % client['id'])
6 #server.send_message_to_all("a new client...")
7 server.send_message(client,"请问有什么可以帮到您？")
8
9
10 # Called for every client disconnecting
11 def client_left(client, server):
12 print("Client(%d) disconnected" % client['id'])
13
14
15 # Called when a client sends a message
16 def message_received(client, server, message):
17 if len(message) > 200:
18 message = message[:200]+'..'
19 print("Client(%d)_address%s said: %s" % (client['id'],client['address'], message))
20 server.send_message(client,'用户编号'+str(client['id'])+':'+message)
21
22
23 PORT=9001
24 server = WebsocketServer(PORT,host="192.168.150.128")
25 server.set_fn_new_client(new_client)
26 server.set_fn_client_left(client_left)
27 server.set_fn_message_received(message_received)
28 server.run_forever()
4.编辑client.html

61 if ("WebSocket" in window){
62 console.log("您的浏览器支持 WebSocket!");
63 var ws = new WebSocket("ws://192.168.150.128:9001");
64 //var ws = new WebSocket("ws://localhost:9001");
65 ws.onopen = function(){

67 }
68
69 ws.onmessage = function (evt) {
70 var dataReceive = evt.data;
71 console.log("数据已接收..."+dataReceive);
72 $('#history').val($('#history').val()+dataReceive+"\n");
73 };
74
75 ws.onclose = function()
76 {
77 console.log("连接已关闭...");
78 };
79
80 }else{
81 // 浏览器不支持 WebSocket
82 console.log("您的浏览器不支持 WebSocket!");
83 }
84
85 function sendMessage(){
86 var dataSend = oWin.val().trim();
87 ws.send(dataSend);
88 oWin.val('');
89 }
90
91 </script>
92 </body>
93 </html>
界面
3.终端运行server.py，然后通过浏览器访问client.html进行连接
终端运行server.py
浏览器访问对话客户端
终端显示
4.接着尝试在客户端发送一句话
