Cách nhận dữ liệu buffer bằng express với multer

[Devil_Chan]

send.js

var buffer = await new Promise( (rs,rj) =>{
     request({
          url : 'domain.com/img.jpeg',
          method : 'get',
          encoding: null
      },function(error, response, body){
            rs(body)                 
      })
})


request({
   method : 'POST',
    url : 'http://localhost:5050/upload', // 
    port : 443,
    headers: {
            'Content-type': 'multipart/form-data' 
    },
    formData : {
         file_name : 'name.jpg',
         file : buffer
    }
})

EXPRESS.js

const express = require("express")
const app = express()
const multer = require('multer')
const upload = multer()
const fs = require('fs')

const imageStorage = multer.memoryStorage()

const imageUpload = multer({
    storage: imageStorage,
    limits: {
        fileSize: 15000000
    }
})

app.post('/upload',imageUpload.single('file'),async function(req, res){
   
	console.log(req.file)
	console.log(req.body)

    res.send(200)
})

const port = 5050

app.listen(port, () => {
    console.log(`Example app listening at http://localhost:${port}`)
})
