使用node.js和localhost html客户端连接的socket.io.js错误
我得到错误socket.io.js：2919和net :: err_connection_refused只是想得到这个解决，感谢需要添加更多的细节来发布此
inheritance人的服务器套接字代码
var app = require('http').createServer(connectHandler), io = require('socket.io').listen(app), fs = require('fs'); app.listen(8080); function connectHandler (req, res) { fs.readFile(__dirname + '/client.html', function (err, data) { if (err) { res.writeHead(500); return res.end('Error loading client.html'); } res.writeHead(200); res.end(data); }); } var members = []; io.sockets.on('connection', function (socket) { socket.on('joined', function(data) { var mbr = data; mbr.id = socket.id; members.push(mbr); socket.broadcast.emit('joined', data); console.log(data.name, 'joined the room'); }); socket.on('message', function(data) { socket.broadcast.emit('message', data); }); socket.on('disconnect', function() { for (var i = 0; i < members.length; i++) { if (members[i].id === socket.id) { socket.broadcast.emit('disconnected', { name: members[i].name }); } } }); }); 这里是html套接字客户端
<!doctype html> <html> <head> <script src="/socket.io/socket.io.js"></script> </head> <body> <div id="messages"> </div> <form id="newChat"> <textarea id="text"></textarea> <input type="submit" id="sendMessage" value="Send" /> </form> <script> var socket = io.connect('http://localhost'); var who; socket.on('connect', function() { var chatter = prompt('Please enter your name'); chatter = (chatter === "" || chatter === null) ? "anon" : chatter; addChatter("you", "Joined"); who = chatter; socket.emit('joined', { name: chatter }); }); function addChatter(name, message) { var chat = document.getElementById("messages"); chat.innerHTML += "<div>" + name + " - " + message + "</div>"; } socket.on('joined', function(data) { console.log(data); addChatter(data.name, ' joined'); }); socket.on('disconnected', function(data) { addChatter(data.name, 'disconnected'); });
html文件中的localhost连接可以通过以下方式在新版本中build立：
var socket = io();
它将自己绑定到服务器上。
请参考http://socket.io/get-started/chat/
作为一个附注; 在服务器上启动连接可以使用：
io.on('connection' ...
代替
io.sockets.on('connection' ...
var app = require('http').createServer(connectHandler), io = require('socket.io').listen(app), fs = require('fs'); function connectHandler (req, res) { fs.readFile(__dirname + '/client.html', function (err, data) { if (err) { res.writeHead(500); return res.end('Error loading client.html'); } res.writeHead(200); res.end(data); }); } var members = []; io.on('connection', function (socket) { console.log(socket); socket.on('joined', function(data) { var mbr = data; mbr.id = socket.id; members.push(mbr); socket.broadcast.emit('joined', data); console.log(data.name, 'joined the room'); }); socket.on('message', function(data) { socket.broadcast.emit('message', data); }); socket.on('disconnect', function() { for (var i = 0; i < members.length; i++) { if (members[i].id === socket.id) { socket.broadcast.emit('disconnected', { name: members[i].name }); } } }); }); app.listen(8077);
