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

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(); }
