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>
