使用Node.js多圖像上傳

Question

我正在處理Node.js並嘗試處理多個圖像。 我使用以下代碼上傳單個圖像，然後將字符串格式的路徑保存到數據庫。

var multiparty = require("multiparty"); 
var form = new multiparty.Form(); 

form.parse(req, function(err, fields, files) { 
    var img = files.image[0]; 
    var fs = require('fs'); 

    fs.readFile(img.path, function(err, data) { 
     var path = "/path/to/upload/" + img.originalFilename; 

     fs.writeFile(path, data, function(error) { 
      if (error) console.log(error); 
     }); 
    }); 
})  

現在如何處理多個圖像。
任何幫助將不勝感激！

var express = require('express'), 
    app = express(), 
    formidable = require('formidable'), 
    util = require('util'), 
    fs = require('fs-extra'), 
    bodyparser=require('body-parser'), 
    qt = require('quickthumb'), 
    path = require('path'); 


var mongoose = require('mongoose'); 
mongoose.connect('mongodb://localhost/db'); 

var Images = require('./model.js'); 



app.use(qt.static(__dirname + '/')); 
app.use(bodyparser()); 
app.set('view engine','ejs'); 


app.post('/upload',function (req, res){ 

     var form = new formidable.IncomingForm(); 
    form.parse(req, function(err, fields, files) { 
      }); 

    form.on('field',function(name,value){ 

     }); 



    form.on('end', function(fields, files) { 

     for(var x in this.openedFiles) 
     { 
       //Images is my model 
       var img = new Images(); 

       var temp_path = this.openedFiles[x].path; 
       /* The file name of the uploaded file */ 
       var file_name = this.openedFiles[x].name; 
       //console.log('file '+file_name); 
       img.size = this.openedFiles[x].size; 
       img.type = this.openedFiles[x].type; 

       /* Location where we want to copy the uploaded file */ 
       var new_location = 'uploads/'; 

       console.log(img.nam=new_location+file_name); 
       img.save(function(err,imgobj) { 
        if (err) 
        throw err; 
       });  
        //to copy the file into a folder   
       fs.copy(temp_path, new_location + file_name, function(err) { 
        if (err) { 
        console.log(err); 
        } 
       });//fscopy 
      }//for loop 

    });//form end 
res.send('Done!!'); 

});//post 
app.listen(3000); 
console.log('started server');
