MERN 使用 multer 上傳文件

[英]MERN Upload file with multer

問題描述

我正在制作一個 pinterest 克隆所以我需要上傳圖像但我無法從前端到后端獲取文件（使用 axios）這是服務器

我測試了很多東西，但我不明白缺陷在哪里。 該應用程序存儲照片，似乎問題發生在我想將數據獲取到后端但只有文件因為我可以從前端獲取字符串

const express = require('express');
const app = express()
const mongoose = require('mongoose')
const cors = require('cors')
const Photo = require('./models/Photo')
const multer = require('multer')
//MiddleWare
app.use(cors())
app.use(express.json())

mongoose.connect('', () =>{
    console.log('Connected to DB..')
})

// storage 
const Storage = multer.diskStorage({
  destination: 'uploads',
  filename: (req, file,cb) =>{
    cb(null, file.originalname)
  }
})

const upload = multer({
  storage: Storage,
}).single('testImage')

app.post('/add', async(req, res) =>{


  console.log(req.files)
})

app.listen(3001, () =>{
    console.log('Listening..')
})

這是客戶端

          <button >Submit</button>
        </form>
      ) : (
        ""
      )}
    </div>
  );
};

export default Header;

當我上傳圖像時，服務器控制台記錄未定義，但為什么？

... console.log(req) 的 output

您是否嘗試記錄req的值？

app.post('/add', async(req, res) =>{
  console.log(req)
})

你正在做axios.post('http://localhost:3001/add',{photo: photo}) 。 根據簽名，第二個密鑰應該是數據： axios.post(url[, data[, config]])

要使用 POST 發送文件，您需要發送FormData的實例。

const bodyFormData = new FormData();
bodyFormData.append("media", file);
axios.post('http://localhost:3001/add',{file: bodyFormData})

在服務器中嘗試根據req的值訪問正確的密鑰。 做req.files
