使用带有NodeJS应用程序的内置套接字

Question

我挥动了一个正常工作的NodeJS应用程序，它正确地使用FFMPEG进行视频转换。我没有运气使用socket.io所以相反我想要Node中的本机套接字类。这是我的节点应用程序到目前为止。
具体来说，我需要在'上发送套接字事件或消息（'结束'，函数（）'

var ffmpeg =  require('./lib/fluent-ffmpeg');

var express = require('express'),
    multer  = require('multer');
var app = express();

//auto save file to uploads folder
app.use(multer({ dest: './uploads/'}))
var temp;

app.post('/', function (req, res) {
    console.log(req.body); //contains the variables
    console.log("req.files ="+ req.files); //contains the file references

console.log("req.files.Filedata.path ="+ req.files.Filedata.path ); 

temp=req.files.Filedata.path;
console.log("temp ="+temp);


// make sure you set the correct path to your video file
var proc = ffmpeg('./'+temp)

  // set audio bitrate
  .audioBitrate('128k')
  // set audio codec
  .audioCodec('libmp3lame')

  // set output format to force
  .format('avi')
  // setup event handlers
  .on('end', function() {
    console.log('file has been converted succesfully');
  })
  .on('error', function(err) {
    console.log('an error happened: ' + err.message);
  })
  // save to file
  .save('./converted/converted.avi');
    res.send('Thank you for uploading!');

});

app.listen(8080);
