Question

我为我的网站开发了一个实时聊天网络应用程序。我的服务器与我需要采取的行动方式略有不同。我有一个Apache PHP服务器，node.js不兼容。我的节点服务器是公共的，但要连接，我必须从服务器命名客户端的目录，这意味着当我打开 SERVER IP时，它将显示客户端。我想在另一个托管服务器上上传客户端，并从那里连接到我的Socket.IO和节点服务器。这是我的代码。

服务器

var http = require('http').createServer(handler);
var io = require('socket.io').listen(http);
var sys = require('sys');
var fs = require('fs');

var clients = [];

http.listen(911);

function handler(request, response) {
    //If the response is Positive (200)
    response.writeHead(200, {
        'Content-Type':'text/html'
    });
    sys.pump(rs, response);
};

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

    var username;

    clients.push(socket);
    socket.emit('welcome', {'salutation':'Welcome to this chat server!'});
    socket.emit('welcome', {'salutation':'Please input your username:'});

    socket.on('data from client', function(data) {
        console.log('message: ' + data.text);
        if(!username) {
            username = data.text;
            socket.emit('data from server', {'message': 'Welcome, ' + username + '!'});
            return;
        }
        //the response when someone types something
        var feedback = username + ' said: ' + data.text;
        clients.forEach(function(socket) {
            socket.emit('data from server', {'message': feedback});
        });
    });

});
