原生nodejs使用websocket代码分享

安装：

npm  install  ws

服务端（nodejs）：

var websocketserver = require('ws').server,
wss = new websocketserver({ port: 8080 });
wss.on('connection', function (ws) {
console.log('client connected');
ws.on('message', function (message) {
  console.log(message);
});
});

客户端：

<script>
var ws = new websocket("ws://localhost:8080");
ws.onopen = function (e) {
  console.log('connection to server opened');
  sendmessage();
}
function sendmessage() {
  ws.send('hello');
}
</script>
