Answer 1

目的地：

   cb(null,'../../../picture')

文件名是：

let path = require('path');

cb(null, file.fieldname + '-' + Date.now()+path.extname(file.originalname))

Answer 2

能够解决问题。

var router = require('express').Router();
var multer  = require('multer');
var storage = multer.diskStorage({
     destination: function (req, file, cb) {
       cb(null,'picture/')
     },
     filename: function (req, file, cb) {
       cb(null, file.originalname)
     }
   })
var upload = multer({ storage })
