创建视图连接池
#-*- coding: utf-8 -*-
#app/views/views_real_time.py
from sockjs.tornado import SockJSConnection class RealTimeHandler(SockJSConnection): #建立连接池 waiters = set() def on_open(self, request): try: self.waiters.add(self) except Exception as e: print(e) #发送消息 def on_message(self, message): try: # self.broadcast(self.waiters,message) except Exception as e: print(e) #关闭连接 def on_close(self): try: self.waiters.remove(self) except Exception as e: print(e)
做路由映射：
#-*- coding: utf-8 -*- from sockjs.tornado import SockJSRouter from app.views.views_index import IndexHandler as index from app.views.views_real_time import RealTimeHandler as real_time #配置路由视图映射规则 urls = [ (r"/",index) ]+SockJSRouter(real_time,"/real/time").urls
导入index.html文件处理路径问题
<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <meta name="description" content=""> <meta name="author" content=""> <title>硬件实时监控</title> <link href="{{static_url(\'dist/css/bootstrap.min.css\')}}" rel="stylesheet"> <link href="{{static_url(\'css/dashboard.css\')}}" rel="stylesheet"> <script src="{{static_url(\'js/analogClock.js\')}}"></script> </head> <body> <nav class="navbar navbar-dark fixed-top bg-dark flex-md-nowrap p-0 shadow"> <a class="navbar-brand col-sm-3 col-md-2 mr-0" href="#">硬件实时监控</a> </nav> <div class="container-fluid"> <div class="row"> <nav class="col-md-2 d-none d-md-block bg-light sidebar"> <div class="sidebar-sticky"> <ul class="nav flex-column"> <li class="nav-item"> <a class="nav-link active" href="#"> 系统监控 </a> </li> <li class="nav-item"> <a class="nav-link active" href="#"> 日志统计 </a> </li> </ul> <div class="col-md-12"> <div class="card text-white bg-dark mb-3"> <div class="card-header">当前时间</div> <div class="card-body" id="clock"></div> </div> </div> </div> </nav> <main role="main" class="col-md-9 ml-sm-auto col-lg-10 px-4"> <div class="d-flex justify-content-between flex-wrap flex-md-nowrap align-items-center pt-3 pb-2 mb-3 border-bottom"> <h5>系统监控</h5> </div> <!--内容部分--> <div class="jumbotron foot-section"> <hr class="my-4"> <div class="container"> <div class="row"> <div class="col-md-2"> <img data-src="{{static_url(\'images/face.png\')}}" class="lazyload blur-up img-fluid mx-auto d-block"> </div> <div class="col-md-4"> <h5>topass123</h5> <p class="info-text">— 人生苦短，我用Python！</p> <p class="info-text">微信：ooooooooooo</p> <p class="info-text">手机：kkkkkkkkkkk</p> <p class="info-text">邮箱：niubi@qq.com</p> <p class="info-text">编程爱好者，擅长python、centos,hadoop集群搭建等技术。</p> </div> <div class="col-md-6"> <div class="row"> <div class="col-md-4"> <p class="text-center info-text">站长微信</p> <img data-src="{{static_url(\'images/weixin.jpg\')}}" class="lazyload blur-up img-fluid mx-auto d-block"> </div> <div class="col-md-4"> <p class="text-center info-text">站长QQ</p> <img data-src="{{static_url(\'images/qq.jpg\')}}" class="lazyload blur-up img-fluid mx-auto d-block"> </div> <div class="col-md-4"> <p class="text-center info-text">python问答QQ群</p> <img data-src="{{static_url(\'images/qq_group.jpg\')}}" class="lazyload blur-up img-fluid mx-auto d-block"> </div> </div> </div> </div> </div> <hr class="my-4"> <div class="container"> <ul class="list-inline text-center"> <li class="info-text"><a href="http://www.miibeian.gov.cn/" target="_blank">滇ICP备17011280号</a> </li> <li class="info-text">© 2020 topass123[学习交流与分享]</li> </ul> </div> </div> </main> </div> </div> <script src="https://cdn.bootcss.com/lazysizes/4.0.2/lazysizes.min.js"></script> <!--导入sockjs-client--> <script src="https://cdn.bootcss.com/sockjs-client/1.3.0/sockjs.min.js"></script> <script src="{{static_url(\'js/monitor.js\')}}"></script> <script> AnalogClock("clock", new AnalogClockOption(200, "#eee", "#333")); </script> </body> </html>
处理系统查找，使用路径拼接的方式
#-*- coding: utf-8 -*-
#app/configs.py
import os root_path = os.path.dirname(__file__) #配置调试模式 configs = dict( debug = True, template_path = os.path.join(root_path,"templates"), static_path = os.path.join(root_path,"static"), )
渲染网页，即可看到完美的页面
#-*- conding: utf-8 -*- import tornado.web #定义一个首页视图 class IndexHandler(tornado.web.RequestHandler): def get(self,*args,**kwargs): self.render("index.html")
最后使用websocketjs实现长连接。
//定义长连接 var conn = null; //定义连接的函数 function connect() { //优先将以前的所有的连接关闭掉。 disconnect(); //定义协议 var transports = ["websocket"]; //创建连接的对象 conn = new SockJS("http://"+window.location.host+"/real/time",transports); //创建连接 conn.onopen=function () { console.log("is success"); }; //连接发送消息 conn.onmessage=function (e) { console.log(e.data) }; //连接关闭 conn.onclose=function () { console.log("is colse") }; //每个几秒触发一个事件,解决连接是否完成的 setInterval(function () { conn.send("system"); },1000); } //定义断开连接函数 function disconnect() { if (conn!=null){ conn.close(); conn=null; } } //刷新页面的时候，处理断开与重连的函数，重连判断 if(conn==null){ connect() }else{ disconnect(); }
