从 cloudinary 中删除原始图像

Question

我正在将 cloudinary 与 node 和 multer 一起使用我成功地存储了图像，但我注意到每次上传图像时它都会创建两个副本：一个以 public_id 作为名称（在资产中），另一个以原始名称（在 'profiles'文件夹）。

每当我上传一张新图片时，我都想删除它们，但它只会删除资产中的一张，而不删除 'profiles' 图片中的一张。

我的上传路径是这样的

import path from "path";
import express from "express";
import dotenv from "dotenv";
import cloudinary from "cloudinary";
import { CloudinaryStorage } from "multer-storage-cloudinary";
import multer from "multer";

dotenv.config();

const cloud = cloudinary.v2;
const router = express.Router();

cloud.config({
  cloud_name: process.env.CLOUDINARY_CLOUD_NAME,
  api_key: process.env.CLOUDINARY_API_KEY,
  api_secret: process.env.CLOUDINARY_API_SECRET,
});

const storage = new CloudinaryStorage({
  cloudinary: cloud, 
  params: {
    folder: "profiles",
    transformation: { gravity: "center", height: 300, width: 300, crop: "fill" },
    public_id: (req, file) =>
      `${file.originalname.split(".")[0]}-${Date.now()}`,
  },
});

function checkFileType(file, cb) {
  const filetypes = /jpg|jpeg|png/;
  const extname = filetypes.test(
    path.extname(file.originalname).toLocaleLowerCase()
  );
  const mimetype = filetypes.test(file.mimetype);
  if (extname && mimetype) {
    return cb(null, true);
  } else {
    cb(null, false);
  }
}

const upload = multer({
  storage,
  fileFilter: function (req, file, cb) {
    checkFileType(file, cb);
  },
});

router.post("/", upload.single("image"), async (req, res) => {
  try {
    const result = await cloud.uploader.upload(req.file.path)
    res.send(result);
  } catch(error) {
    console.log(error)
  }
});

export default router;

以及删除路由

import express from "express";
import dotenv from "dotenv";
import cloudinary from "cloudinary";

dotenv.config();

const cloud = cloudinary.v2;
const router = express.Router();

cloud.config({
  cloud_name: process.env.CLOUDINARY_CLOUD_NAME,
  api_key: process.env.CLOUDINARY_API_KEY,
  api_secret: process.env.CLOUDINARY_API_SECRET,
});

router.post('/:id', async (req, res) =>{
    try {
        await cloud.uploader.destroy(req.params.id);
        // await cloud.uploader.destroy(`/profiles/${req.params.id}`);

        res.send(result);
    } catch (err) {
        return res.status(500).json({msg: err.message})
    }
    
})

export default router;

有人能帮忙吗？

以防有人遇到同样的问题我在上传路径中发送了两次图像改成这个

router.post("/", upload.single("image"), async (req, res) => {
  try {
    res.json(req.file);
  } catch (error) {
    console.log(error);
  }
});
