我很难尝试设置节点服务器来在 c9.io 上运行一个简单的应用程序。首先,服务器在本地主机上运行没有问题,但由于某种原因,c9 渲染了 html,但不使用 socket.io.. 这是我的代码:

应用程序.js

const http = require('http');
const socketio = require('socket.io');
const express = require('express');

const app = express();
const server = http.createServer(app);
const io = socketio.listen(server);

app.get('/', (req, res) => res.sendFile(`${__dirname}/client/index.html`))

io.on('connection', socket => {
socket.on('move', data => {
io.emit('move', data)
})
})

server.listen(process.env.PORT || 3000, process.env.IP || "0.0.0.0", () => {
const addr = server.address();
console.log("Chat server listening at", `${addr.address}:${addr.port}`);
});

index.html

<!doctype html>
<html lang="en" ng-app>
<head>
<title>Chat Example</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" href="/css/bootstrap.min.css">
<link rel="stylesheet" href="/css/bootstrap-responsive.min.css">
<style>
body {
padding-top: 60px;
}
</style>
<script>
const socket = io.connect('https://socket-alexcnu.c9users.io/'); /* global io $*/

$(document).on('mousemove', e => {
let data = {x: e.pageX - 10 , y: e.pageY - 10}
$('div').css({
left: e.pageX - 10,
top: e.pageY - 10
});

socket.emit('move', data)
});

socket.on('move', data => {
console.log(data.x);
$('div').css({
left: data.x,
top: data.y
});
})

</script>
</head>
<body>
<div style = 'height: 20px; width: 20px; background: orange; position:absolute; float:left'></div>

</body>
<script src="/socket.io/socket.io.js"></script>
<script src="/js/jquery.min.js"></script>
</html>

c9 控制台

alexcnu:~/workspace $ node app

最佳答案

以下内容对我有用:

<!doctype html>
<html lang="en" ng-app>
<head>
<title>Chat Example</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script src="https://cdn.socket.io/socket.io-1.4.5.js"></script>
<style>
body {
padding-top: 60px;
}
</style>
<script>
const socket = io.connect('https://socket-alexcnu.c9users.io/'); /* global io $*/

$(document).on('mousemove', e => {
let data = {x: e.pageX - 10 , y: e.pageY - 10}
$('div').css({
left: e.pageX - 10,
top: e.pageY - 10
});

socket.emit('move', data)
});

socket.on('move', data => {
console.log(data.x);
$('div').css({
left: data.x,
top: data.y
});
})

</script>
</head>
<body>
<div style = 'height: 20px; width: 20px; background: orange; position:absolute; float:left'></div>

</body>
</html>
