为什么我的node.js / socket.io应用程序无法在iOS6上运行？ [英] Why does my node.js / socket.io app not work on iOS6?
问题描述
我认为socket.io的重点是不必担心现代浏览器？ lol
I thought the whole point of socket.io was to not have to worry about modern browsers? lol
无论如何，我是套接字编程的新手。我有一个小应用程序，只是模仿鼠标移动。
Anyway, I am new to socket programming. I have a small app that simply mimics mouse movements.
您打开几个浏览器，当您移动鼠标时，您的操作将记录在其他浏览器中。它移动一个小方块。有点酷。但是，当我在iPad（iOS6）上打开它时什么都没有！套接字没有连接。我甚至在 connect 事件中放了一条警告信息，没有任何内容。
You open several browsers and when you move the mouse, your actions are recorded in the other browsers. It moves a small square. Kinda cool. However, when I open it on my iPad (iOS6) nothing! Sockets isn't connecting. I even put an alert message in the connect event and nothing.
在IE，FF和Chrome中工作就好了在我的笔记本上。唯一的区别是我的开发机器使用 localhost 而iPad使用我的机器的IP。但是，当我在笔记本电脑上连接到我的本地IP时，它仍然有效。只是不在Safari / iPad中。
Works in IE, FF and Chrome just fine on my laptop. The only difference is that my dev machine uses localhost while the iPad uses my machine's IP. However, when I connect to my local IP on my laptop, it still works. Just not in Safari/iPad.
这是我的服务器。
var app = require('http').createServer(handler),
io = require('socket.io').listen(app),
fs = require('fs');
app.listen(80);
function handler(req, res) {
var file = __dirname + '/public/index.html';
fs.readFile(file,
function(err, data) {
if(err) {
res.writeHead(500);
return res.end('Error loading index.html');
}
res.writeHead(200);
res.end(data);
}
);
}
var rooms = ['abc', 'test1'];
var sockets = [];
io.sockets.on('connection', function(socket) {
sockets.push(socket);
socket.on('m', function(data) {
socket.broadcast.to(socket.room).emit('relay', {msg: 'MouseX: ' + data.x + ' MouseY: ' + data.y, x: data.x, y: data.y});
});
socket.on('join', function(room) {
socket.join(room);
socket.emit('updateStatus', {msg: 'Joined room ' + room});
console.log('Joined room ' + room);
});
});
这是我的客户：

<script>
var socket = io.connect('http://localhost');
var b = document.getElementById('box');
var m = document.getElementById('msg');
var c = document.getElementById('cursor');
// join custom room
socket.on('connect', function() {
socket.emit('join', 'abc');
});
// update status messages from server
socket.on('updateStatus', function(data) {
m.setAttribute('value', data.msg);
});
socket.on('relay', function(data) {
b.setAttribute('value', data.msg);
c.style.left = parseInt(data.x) + 'px';
c.style.top = parseInt(data.y) + 'px';
});
document.onmousemove = function(event) {
event = event || window.event;
socket.emit('m', {x: event.clientX, y: event.clientY});
}
</script>
</body>

推荐答案
Localhost是本机的本地。你应该使用IP地址或域名：
Localhost is local to the machine. You're IP should use a ip address or domain name:
类似于：
io.connect（'192.168.1.110'）;
或io.connect（'test.myapp.com'）;
something like: io.connect('192.168.1.110'); or io.connect('test.myapp.com');
