我正在使用 Node.js 和 Socket.io 开发聊天应用程序。这是我的代码。|
socket.js
var io = require('socket.io').listen(8001);
var http = require('http');
var url = require('url');
var fs = require('fs');
// open the socket connection
io.sockets.on('connection', function (socket) {
// listen for the chat even. and will recieve
// data from the sender.
socket.on('chat', function (data) {
// default value of the name of the sender.
var sender = 'unregistered';
// get the name of the sender
socket.get('nickname', function (err, name) {
console.log('Chat Message By: ', name);
console.log('error ', err);
sender = name;
});
// broadcast data recieved from the sender
// to others who are connected, but not
// from the original sender.
socket.broadcast.emit('chat', {
msg : data,
msgr : sender
});
});
// listen for user registrations
// then set the socket nickname to
socket.on('register', function (name) {
// make a nickname paramater for this socket
// and then set its value to the name recieved
// from the register even above. and then run
// the function that follows inside it.
socket.set('nickname', name, function () {
// this kind of emit will send to all! :D
io.sockets.emit('chat', {
msg : "Hello " + name + '!',
msgr : "Mr.Server"
});
});
});
});

我从命令提示符运行第一个 socket.js。之后，我在浏览器中运行 .html 文件 2 次。现在 2 个用户可以通过浏览器聊天。但是，当我尝试将我的 .js 文件和 .html 文件放在使用 FileZila 创建并运行 .js 文件的服务器上时，它正在运行，但是当我尝试在服务器端运行 .html 文件时（在这种情况下为 FileZila ) ，通过提供它未运行的服务器的 IP 地址和端口号。你能告诉我有什么问题吗？
