将图像上传到节点.js图像“未定义

对不起，缩进很差我是节点新手.js尝试将图像上传到节点.js检查很多答案，如果我错了，请责备我

1.bodyParser 需要一个中间件来处理二进制文件，比如 IMAGE如果我不使用它，它会显示

undefine token

2.使用Multer作为中间件，像这样

var multer = require('multer') 
var upload = multer({ dest:'/Node/file-upload/uploads/' });
app.post('/upload',upload.array(),songs.upload);

3. 按照这个，req.files是图像文件，req.body是文件名所以我使用 fs.readFile 来读取文件

fs.readFile(req.files.image.path, function (err, data)

4.比我需要文件路径和文件名，我使用req.body

var dirname = "/Node/file-upload/uploads/";
var newPath = dirname + req.body.image.filename;

5.通过此将数据写入目标

fs.writeFile(newPath, data, function (err)

我不确定我错过了哪一部分，我花了 10 个小时才做到这一点，请帮忙

它总是告诉我类型错误：无法读取未定义的属性"图像"

应用.js

var    express = require('express')
      ,bodyParser = require('body-parser')
      ,app = express()
      ,multer  =  require('multer')
      ,binary = require('binary')
      ,fs = require('fs')
      ,util= require('util')
      ,http = require('http')
      ,multer = require('multer')
      ,upload = multer({ dest: '/Node/file-upload/uploads/' });
 app.use(bodyParser.urlencoded({ extended: true })); // support encoded bodies.
 app.use(bodyParser.json({limit: '5mb'}));

songs = require('./routes/route');
app.listen(3000, function () {
      console.log('Example app listening on port 3000!');
                          });
app.post('/upload',upload.array(),songs.upload);

路线.js

var mongoose = require('mongoose');
var uri = "mongodb://xxxxxx:xxxxxxx@ds061365.mongolab.com:61365/aweitest";
mongoose.connect(uri);
// we're connected!
var db = mongoose.connection.db;
var BSON = require('bson').BSONPure;
var binary = require('binary');
var body = require('body-parser');
var fs = require('fs');
db.on('error', console.error.bind(console, 'connection errrrrrrrror:'));
db.once('open', function() {
     console.log("mongodb is connected!!");
 });
exports.upload = function(req, res) {
    console.log(req.body);
       fs.readFile(req.files.image.path, function (err, data){
            var dirname = "/Node/file-upload/uploads/";
            var newPath = dirname + req.body.image.filename;
       fs.writeFile(newPath, data, function (err) {
            if(err){
                res.json({'response':"Error"});
            }else {
                res.json({'response':"Saved"});
          }
       });
    });
  };
