Question

我目前正在尝试使用socket.IO。但是由于某种原因，我没有收到来自客户的发射。我正在使用Node.js并表示要托管html文件。

这是我当前的代码： server.js

var express = require('express');
var app = express();
var path = require('path');
var http = require('http').Server(app);
var io = require('socket.io')(http);

var d = new Date();
var temp = d.getHours() + ':' + d.getMinutes() + ':' + d.getSeconds();

app.get('/', function(req, res){
  //res.sendFile(__dirname + '/public/index.html');
  app.use(express.static('public'));
});

io.on('connection', function(socket){
  console.log(temp + ' :A User connected');
  console.log('Socket ID: ' + socket.id);
    socket.on('disconnect', function(){
      console.log(temp +' :A User disconnected');
      console.log('Socket ID: ' + socket.id);
        socket.on('testCon', function(){
          console.log('Received');
        });
  });
});



http.listen(3000, function(){
  console.log('listening on *:3000');
});

  <body>
    <p>Socket Test Site</p>
    <button onclick="newConnection();">Connect</button>
    <button onclick="myFunction();">Execute</button>
  </body>
</html>

client.js

var socket;

function newConnection() {
  socket = io();
}

function myFunction() {
  socket.emit('testCon', null);
  console.log("Button Pressed");
}

我不确定现在是什么问题。

谢谢！

为什么我的node.js服务器没有收到套接字io发出？
