Question

我正在尝试在端口8080上连接到套接字服务器，但始终收到此错误Connection to IPAddress:8080 timed out! 这是我的服务器代码

const express = require("express");
var http = require('http').createServer(app);
var io = require('socket.io');
const socket = io(http);
http.listen(8080, () => {
    console.log(`Server is running on port ${PORT}.`);
});

请问如何解决？

Answer 1

您必须编写更多无法直接连接到套接字的套接字代码您必须编写连接功能

请遵循此tutorial来了解套接字的基础知识

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

var port =  8080; // set our port

app.get('/', function(req, res) {
   res.sendfile('index.html');
});

io.on("connection", function (socket) {
    // Everytime a client logs in, display a connected message
    console.log("Server-Client Connected!");

   socket.on('disconnect', function () {
      console.log('A user disconnected');
   });
});

http.listen(port, () => {
    console.log('Magic happens on port ' + port); // shoutout to the user
});

index.html

<!DOCTYPE html>
<html>
   <head>
      <title>Hello world</title>
   </head>
   <script src = "/socket.io/socket.io.js"></script>
   
   <script>
      var socket = io();
   </script>
   <body>Hello world</body>
</html>

运行服务器检查localhost:8080

后

无法与套接字服务器连接
