我正在開發如何使用Node.js和Socket.io聊天應用。 這是我的代碼。|聊天應用程序中使用Socket.io和Node.js的
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"
});
});
});
});

我正在從命令提示符第一socket.js。之後，我在瀏覽器中運行.html文件2次。現在2個用戶可以通過瀏覽器聊天。但是，當我試圖把我的.js文件和HTML文件上，我已經使用FileZila和運行.js文件中創建的服務器，它在運行，但是當我試圖運行在服務器端的.html文件（在這種情況下FileZila ），通過給出服務器的IP地址和端口號未運行。你能告訴我有什麼問題嗎？
你能澄清一下嗎？ 「在服務器端運行.html文件」是什麼意思？你怎麼看到「它沒有運行」？是否有機會忘記確保'socket.io.js'在服務器端的路徑中？ – CFrei
run.html表示客戶端將通過提供IP地址在瀏覽器上運行它。 –
socket.io.js我必須進行更改嗎？ –
