<!DOCTYPE html>

<head>
    <title>Hello WebSocket</title>
    <link href="/webjars/bootstrap/css/bootstrap.min.css" rel="stylesheet">
    <link href="/main.css" rel="stylesheet">
   <script src="https://cdnjs.cloudflare.com/ajax/libs/socket.io/2.0.3/socket.io.js"></script>
<script>
  var socket = io('http://wechat.daopeng365.com');
  socket.on('connect', function(){});
  socket.emit('sendDevnum', '6961616647311138');
  socket.on('messageevent', function(data){console.log(data)});
  </script>
