socketio與vue-cli的結(jié)合使用的示例代碼

npm install -s socket.io
npm install -s vue-socket.io
npm install -s socket.io-client

var sever=require('http').createServer();
var io=require('socket.io')(sever)

io.on('connection', function (socket) {
  socket.on('login',function(data){ //接收連接中的login事件
    console.log(data);
    io.emit('loginmsg','你發(fā)過來的數(shù)據(jù)是：'+data) //發(fā)送回去 事件名為loginmsg
   })

})
console.log('socket端口：8000');
sever.listen(8000)

script{ "server": "node sever/app.js"}

Vue.use(VueSocketio, socketio('ws://127.0.0.1:8000'));//與websocket服務(wù)端鏈接
