我是nodejs的新手。我刚刚在node和socket.io中学到了非常简单的东西。直到现在我从外部文件夹练习，我，不在本地服务器或实时服务器。现在我想在本地服务器上做。我有我的文件夹结构像这样：
xampp\htdocs\socketexmp->
.node-modules
.chat.js
.chat.html
我已将chat.html文件指向虚拟服务器主机名：
http://dev.chatexmp.com
在端口8080上运行。节点服务器在端口：8000上运行。 我的这两个文件如下。 chat.js
var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);
app.get('/', function(req, res){
res.sendFile('chat.html',{root:__dirname});
});
users = [];
io.on('connection', function(socket){
console.log('A user connected');
socket.on('setUsername', function(data){
console.log(data);
if(users.indexOf(data) > -1){
socket.emit('userExists', data + ' username is taken! Try some other username.');
}
else{
users.push(data);
socket.emit('userSet', {username: data});
}
});
socket.on('msg', function(data){
//Send message to everyone
io.sockets.emit('newmsg', data);
})
});
http.listen(8000, function(){
console.log('listening on localhost:8000');
});
和chat.html
<!DOCTYPE html>
<html>
<head><title>Hello world</title></head>
<!-- <script src="/socket.io/socket.io.js"></script> -->
<script src="http://localhost:8000/socket.io/socket.io.js"></script>
<script>
var socket = io();
function setUsername(){
socket.emit('setUsername', document.getElementById('name').value);
};
var user;
socket.on('userExists', function(data){
document.getElementById('error-container').innerHTML = data;
});
socket.on('userSet', function(data){
user = data.username;
document.body.innerHTML = '<input type="text" id="message">\
<button type="button" name="button" onclick="sendMessage()">Send</button>\
<div id="message-container"></div>';
});
function sendMessage(){
var msg = document.getElementById('message').value;
if(msg){
socket.emit('msg', {message: msg, user: user});
}
}
socket.on('newmsg', function(data){
if(user){
document.getElementById('message-container').innerHTML += '<div><b>' + data.user + '</b>: ' + data.message + '</div>'
}
})
</script>
<body>
<div id="error-container"></div>
<input id="name" type="text" name="name" value="" placeholder="Enter your name!">
<button type="button" name="button" onclick="setUsername()">Let me chat!</button>
</body>
</html>
目前，我正在运行此示例，方法是启动节点服务器并转到浏览器并输入：
localhost:8000
一切正常。我可以聊天我现在想要的是，我想去我的虚拟主机：
http://dev.chatexmp.com:8080
让它发挥作用。但它不起作用。我见过this和this等教程。可能是他们很好，但我的水平很低，无法理解。任何人都可以让我明白我该怎么做才能让它发挥作用。谢谢。
这是apache配置文件i，httpd.conf
#
# This is the main Apache HTTP server configuration file. It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.4/> for detailed information.
# In particular, see
# <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "logs/access_log"
# with ServerRoot set to "/usr/local/apache2" will be interpreted by the
# server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log"
# will be interpreted as '/logs/access_log'.
#
# NOTE: Where filenames are specified, you must use forward slashes
# instead of backslashes (e.g., "c:/apache" instead of "c:\apache").
# If a drive letter is omitted, the drive on which httpd.exe is located
# will be used by default. It is recommended that you always supply
# an explicit drive letter in absolute paths to avoid confusion.
#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path. If you point
# ServerRoot at a non-local disk, be sure to specify a local disk on the
# Mutex directive, if file-based mutexes are used. If you wish to share the
# same ServerRoot for multiple httpd daemons, you will need to change at
# least PidFile.
#
ServerRoot "E:/xampp/apache"
#
# Mutex: Allows you to set the mutex mechanism and mutex file directory
# for individual mutexes, or change the global defaults
#
# Uncomment and change the directory if mutexes are file-based and the default
# mutex file directory is not on a local disk or is not appropriate for some
# other reason.
#
# Mutex default:logs
#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80
Listen 80
Listen 8080
