我的代码是这样写的。

var storage = multer.diskStorage({
  destination: function (req, file, cb) {
    cb(null, 'upload1/')
  },
  filename: function (req, file, cb) {
    var singfileArray = file.originalname.split('.');
    var fileExtension = singfileArray[singfileArray.length - 1];
    cb(null, singfileArray[0] + '-' + Date.now() + "." + fileExtension);
    console.log(file);
  }
})

var upload = multer({
  storage: storage
})

router.post('/savedata', upload.single('logo'), function (req, res, next) {
  res.json({
    name: req.body.name,
    age: 10,
    range: [1, 2, 3, 4, 5, 6, 7]
  });
});

 控制台打印的信息

{ fieldname: 'logo',
originalname: '可视化宣传材料.docx',
encoding: '7bit',
mimetype:
'application/vnd.openxmlformats-officedocument.wordprocessingml.document' }
