在Windows 7上为node.js安装socket io
当我运行节点服务器时，控制台显示“info - socket.io started”。但是，它永远不会检测到来自客户端的连接。我相信这是安装 socket.io 的问题，因为我运行的是 Windows 7 机器...
当我尝试从客户端连接到服务器时，我的服务器控制台指示“调试 - 提供静态内容/ lib/socket.io.js”。
有人对如何让套接字 io 从 Windows 7 计算机上的客户端成功连接有任何建议吗？
现在，我的 socket.io 文件夹位于以下目录中：
nodejs/node_modules/socket.io/
对于 node< 中的 tcp 服务器，我在服务器端上有以下代码/strong>：
var http = require('http'),
sys = require('util'),
fs = require('fs'),
io = require('socket.io');
console.log('Creating server...');
var server = http.createServer(function(request, response) {
response.writeHead(200, {
'Content-Type': 'text/html'
});
var rs = fs.createReadStream(__dirname + '/template.html');
sys.pump(rs, response);
});
var socket = io.listen(server);
socket.on('connection', function(client) {
var username;
console.log('New client connected.');
client.send('Welcome to this socket.io chat server!');
client.send('Please input your username: ');
client.on('message', function(message) {
if (!username) {
username = message;
client.send('Welcome, ' + username + '!');
return;
}
socket.broadcast(username + ' sent: ' + message);
});
});
server.listen(20000);
这是客户端的代码：

var socket = new io.Socket('localhost', {port: 20000});

console.log('connect');
});
socket.on('message', function(message) {

entry_el.attr('value', '');

谢谢！
When I run the node server, the console indicates "info - socket.io started". However, it never detects a connection from the client side. I believe it is an issue with the installation of socket.io as I am running a Windows 7 machine...
When I attempt to connect to the server from the client side my server console indicates "debug - served static content /lib/socket.io.js".
Anyone have any suggestions how I can get socket io to succesfully connect from the client side on my Windows 7 machine?
Right now, I have the socket.io folder located in the following directory:
nodejs/node_modules/socket.io/
I have the following code on the server side for a tcp server in node:
var http = require('http'),
sys = require('util'),
fs = require('fs'),
io = require('socket.io');
console.log('Creating server...');
var server = http.createServer(function(request, response) {
response.writeHead(200, {
'Content-Type': 'text/html'
});
var rs = fs.createReadStream(__dirname + '/template.html');
sys.pump(rs, response);
});
var socket = io.listen(server);
socket.on('connection', function(client) {
var username;
console.log('New client connected.');
client.send('Welcome to this socket.io chat server!');
client.send('Please input your username: ');
client.on('message', function(message) {
if (!username) {
username = message;
client.send('Welcome, ' + username + '!');
return;
}
socket.broadcast(username + ' sent: ' + message);
});
});
server.listen(20000);
This is the code on the client side:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Chat</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js"></script>
<script type="text/javascript" src="http://localhost:20000/socket.io/lib/socket.io.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var entry_el = $('#entry');
var socket = new io.Socket('localhost', {port: 20000});
socket.connect();
console.log('connecting...');
socket.on('connect', function() {
console.log('connect');
});
socket.on('message', function(message) {
var data = message.replace(/&/g,"&").replace(/</g,"<").replace(/>/g,">");
$('#log ul').append('<li>' + data + '</li>');
window.scrollBy(0, 1000000000000000);
entry_el.focus();
});
entry_el.keypress(function(event) {
if (event.keyCode != 13) return;
var msg = entry_el.attr('value');
if (msg) {
socket.send(msg);
entry_el.attr('value', '');
}
});
