如何使用nodejs和socket.io在php中实现私聊

Question

我已经使用这个实现了聊天应用程序（https://github.com/jdutheil/nodePHP),but 现在我想要两个用户之间的私人聊天，但我不知道如何实现它。请帮我解决以下问题。

当用户登录他的帐户时，它会列出（使用带有朋友姓名的超链接）他的朋友，例如 Facebook，并带有与之关联的唯一 ID，单击每个项目时，它会打开带有文本框和按钮的新聊天页面并开始聊天。这里是代码

开始聊天-with-friends.php

<?php
  //uniqueid of the friend
  $id=$_GET['id'];
?>
<form class="form-inline" id="messageForm">
                <input id="messageInput" type="text" class="input-xxlarge" placeHolder="Message" />
                <input type="submit" class="btn btn-primary" value="Send" />
            </form>

chatclient.js

$( "#messageForm" ).submit( function() {
var msg = $( "#messageInput" ).val();
socket.emit('join', {message:msg} );
    $( "#messageInput" ).val('');
});



chatServer.js**

socket.on('join', function( data ) {

io.sockets.emit('new_msg'+data.to,{message:data.message});
    });

你好，这可能对你有帮助

var users = {};
var sockets = {};

io.sockets.on('connection', function(socket) {

// Register your client with the server, providing your username
socket.on('init', function(username) {
    users[username] = socket.id;    // Store a reference to your socket ID
    sockets[socket.id] = { username : username, socket : socket };  // Store a reference to your socket
});

// Private message is sent from client with username of person you want to 'private message'
socket.on('private message', function(to, message) {
    // Lookup the socket of the user you want to private message, and send them your message
    sockets[users[to]].emit(
        'message', 
        { 
            message : message, 
            from : sockets[socket.id].username 
        }
    );
});
});
