例如,我的想法是:
File1.js
io.sockets.on('connection', function (socket) {
socket.on('file1Event', function () {
//logic
});
});
File2.js
io.sockets.on('connection', function (socket) {
socket.on('file2Event', function () {
//logic
});
});
这段代码是针对节点服务器的,我会在这段代码上遇到问题吗?
最佳答案
不,只需使用相同的“io”对象即可。
File1.js
exports = module.exports = function(io){
io.sockets.on('connection', function (socket) {
socket.on('file1Event', function () {
console.log('file1Event triggered');
});
});
}
File2.js
exports = module.exports = function(io){
io.sockets.on('connection', function (socket) {
socket.on('file2Event', function () {
console.log('file2Event triggered');
});
});
}
app.js
var app = require('http').createServer(handler)
, io = require('socket.io').listen(app)
, fs = require('fs')
, file1 = require('./File1')(io)
, file2 = require('./File2')(io)
app.listen(3000);
function handler (req, res) {
fs.readFile(__dirname + '/index.html',
function (err, data) {
if (err) {
res.writeHead(500);
return res.end('Error loading index.html');
}
res.writeHead(200);
res.end(data);
});
}
index.html
<script src="/socket.io/socket.io.js"></script>
<script>
var socket = io.connect('http://localhost');
socket.emit('file1Event'); // 'file1Event triggered' will be shown
socket.emit('file2Event'); // 'file2Event triggered' will be shown
</script>
