python实现WebsocketServer 服务端
小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.
python 實現(xiàn)weisocket服務(wù)端用到的庫為：websocket-server 0.4? ：
https://pypi.org/project/websocket-server/0.4/
https://github.com/Pithikos/python-websocket-server
服務(wù)端代碼：
#coding:utf-8from lib.socket.websocket_server import WebsocketServerdef startWebsocketServer():def new_client(client, server):server.send_message_to_all("Hey all, a new client has joined us")def mysend(client,server,msg):print(msg)server.send_message(client,"哈哈哈哈哈")if(msg == "_end"): #如果收到了_end 消息，那么斷開連接server.server_close()server = WebsocketServer(5005, host='127.0.0.1', loglevel=logging.INFO)server.set_fn_new_client(new_client)server.set_fn_message_received(mysend)server.run_forever()server.server_close()if __name__ == "__main__":startWebsocketServer()網(wǎng)頁端代碼：
<!DOCTYPE HTML> <html><head><meta charset="utf-8"><title>websocket測試</title><script type="text/javascript">ws = null;i = 1;(function(){ws = null;i = 1;})()function WebSocketTest(){if ("WebSocket" in window){console.log("您的瀏覽器支持 WebSocket!");ws = new WebSocket("ws://127.0.0.1:5005");ws.onopen = function(){// Web Socket 已連接上，使用 send() 方法發(fā)送數(shù)據(jù)//ws.send("hello world ！");console.log("socket 已經(jīng)連接上！")};ws.onmessage = function (evt) { var received_msg = evt.data;console.log(evt.data)};ws.onclose = function(){ // 關(guān)閉 websocketalert("連接已關(guān)閉..."); };}else{// 瀏覽器不支持 WebSocketconsole.log("您的瀏覽器不支持 WebSocket!");}}function sendMsg(){ws.send("hello world" + i++);}function myclose(){ws.send("_end");ws.close()console.log("執(zhí)行了斷開連接...")}</script></head><body><div id="sse"><button onclick="WebSocketTest()">連接服務(wù)器</button><button onclick="sendMsg()">發(fā)送消息</button><button onclick="myclose()">斷開連接</button></div></body> </html>?
