I create a simple socket.io project in my server but I have errors my ip that I am work on it is http://5.61.25.90/~socket on all files are stored in public_html with URL : http://5.61.25.90/~socket/public_html
& here is my codes
<!doctype html>
<html>
<head>
<title>Socket.IO chat</title>
<style>
* { margin: 0; padding: 0; box-sizing: border-box; }
body { font: 13px Helvetica, Arial; }
form { background: #000; padding: 3px; position: fixed; bottom: 0; width: 100%; }
form input { border: 0; padding: 10px; width: 90%; margin-right: .5%; }
form button { width: 9%; background: rgb(130, 224, 255); border: none; padding: 10px; }
#messages { list-style-type: none; margin: 0; padding: 0; }
#messages li { padding: 5px 10px; }
#messages li:nth-child(odd) { background: #eee; }
#messages { margin-bottom: 40px }
</style>
</head>
<body>
<ul id="messages"></ul>
<form action="">
<input id="m" autocomplete="off" /><button>Send</button>
</form>
<script src="https://cdnjs.cloudflare.com/ajax/libs/socket.io/1.7.4/socket.io.js"></script>
<script src="https://code.jquery.com/jquery-1.11.1.js"></script>
<script>
$(function () {
var socket = io();
$('form').submit(function(){
socket.emit('chat message', $('#m').val());
$('#m').val('');
return false;
});
socket.on('chat message', function(msg){
$('#messages').append($('<li>').text(msg));
window.scrollTo(0, document.body.scrollHeight);
});
});
</script>
</body>
</html>
the above code was the index.html file and in the bottom we have index.js
var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);
var port = process.env.PORT || 3000;
app.get('/', function(req, res){
res.sendFile(__dirname + '/index.html');
});
io.on('connection', function(socket){
socket.on('chat message', function(msg){
io.emit('chat message', msg);
});
});
http.listen(port, function(){
console.log('listening on *:' + port);
});
and now I have 404 error in the console panel
like this
http://5.61.25.90/socket.io/?EIO=3&transport=polling&t=LqRzAYF 404 not found socket.io.js(line 4948)
In my opinion this could help:
app.get('*', function(req, res) {
instead of this:
app.get('/', function(req, res) {
Your app router in the backend is only catching the route '/'. So it can't handle requests, that do not match the route exactly.
