使用 multer 在我的 MERN 前端显示 MongoDB 图像的正确语法是什么

我正在try 发出GET请求，以接收我的MongoDB中存在的帖子.我正在使用Multer中间件，很难在前端显示图像.

我的后端代码如下所示: (posts.js)

import express from "express";
import multer from "multer";
import Posts from "../models/posts.js";


const storage = multer.diskStorage({
  destination: function (req, file, cb) {
    cb(null, "uploads/");
  },
  filename: function (req, file, cb) {
    cb(null, Date.now() + "-" + file.originalname);
  },
});

const upload = multer({ storage: storage });

const router = express.Router();

router.route("/create").post(upload.single('file'), async (req,res)=>{
  try {
    const post = new Posts({
      title: req.body.title,
      description: req.body.description,
      amt: req.body.amt,
      artist_name: req.body.artist_name,
       // Use fileType instead of req.body.type
      
      art_image: req.file.filename,
    });

    const savedPodcast = await post.save();
    res.status(201).json(savedPodcast);
  } catch (err) {
    console.error(err);
    res.status(500).json({ message: "Internal server error" });
  }
});

router.route("/feed").get( async (req, res) => {
  try {
    const getPosts = await Posts.find();
    console.log(getPosts)
    res.json(getPosts);
   
  } catch (error) {
    res.status(500).json({ message: "Error fetching posts", error });
  }
});


export default router

此代码绑定到app.use('/feed', feedRoute)并被调用.我的GET请求正确地检索数据库中的数据，如下所示:

[
  {
    _id: new ObjectId("6479438fdf4ff1fc5cf2eab8"),      
    artist_name: 'sad',
    title: 'gfds',
    description: 'adf',
    amt: '234',
    reportCount: 0,
    upvote: 0,
    createdAt: 2023-06-02T01:19:02.297Z,
    art_image: '1685668751687-event_juntion.png',       
    apply_watermark: true,
    __v: 0
  }
]

然而，我不能理解如何使用art_image文件路径在前端显示它.我应该在img标签的src中写什么？
