使用对象值创建文件夹

Question

我正在学习 Nodejs，并且正在尝试为每个新用户创建文件夹。该文件夹将链接到用户名（单击它时将打开文件夹/ftp）我正在使用 Admin-bro 界面。这是用户对象。const { model } = require("mongoose");const User = model("User", {  name: String,  surname: String,  age: Number,  email: String,  description: String});module.exports = User;用户路由器：const { Router } = require('express')const paginate = require('../services/paginate.service')const User = require('../models/user.model')const dir = require('../routers/ftp')const router = new Router()const serializer = (user) => {  return user.toObject({ versionKey: false })}router.get('/', async (req, res) => {  const users = await paginate(User.find({}), req)  res.send(users.map(serializer))})router.post('/', async (req, res) => {  const user = await new User(req.body.user).save()  res.send(serializer(user))})module.exports = router我不知道如何为我添加的每个新用户创建一个文件夹，将 name_surname 作为文件夹名称。我试图创建一个路由器但失败了。这是我尝试过的："use strict";module.exports = function(app) {  const fs = require("fs");  const path = require("path");  const multer = require("multer");  const storage = multer.diskStorage({    desctination: function(req, file, cb) {      const uploadDir = path.join(__dirname, "..", "..", `${Date.now()}`);      fs.mkdirSync(uploadDir);      cb(null, uploadDir);    },    filename: function(req, file, cb) {      cb(null, file.originalname);    }  });  const upload = multer({ storage });  const controller = require("../routers/createDir");};PS：没有控制器，因为我不知道该怎么做。请给我一个建议或链接，我可以在其中了解它是如何完成的。谢谢

Answer 1

我愿意将用户名或 id 传递给文件夹并动态创建它，而不是手动创建。像这样

const multer = require("multer");

const storage = multer.diskStorage({

  destination: (req, file, cb) => {

    const { userId } = req.body;

    const dir = `../uploads/${userId}`;

    fs.exists(dir, exist => {

      if (!exist) {

        return fs.mkdir(dir, error => cb(error, dir));

      }

      return cb(null, dir);

    });

  },

  filename: (req, file, cb) => {

    const { userId } = req.body;

    cb(null, `UserId-${userId}-Image-${Date.now()}.png`);

  }

});

const upload = multer({ storage });

用户mkdrp节点模块包

var mkdirp = require('mkdirp');

mkdirp('/tmp/foo/bar/baz', function (err) {

  if (err) console.error(err)

  else console.log('pow!')

});
