I am trying to upload multiple files using Multer on a NodeJs environment :



const storage = multer.diskStorage(
destination: function (req, file, cb)
cb(null, 'my_uploads/')
,
filename: function (req, file, cb)
cb(null, req.body.original_name)

)

const upload = multer(
storage: storage
)

app.post('/file_upload', upload.any(), function (req, res, next)
console.log('>>> nt' + JSON.stringify(req.files))
res.json(
success: true,
message: 'Photo was updated !'
)
)


I have some multipart data that get sent with the files on to the server :



console.log('>>> nt' + JSON.stringify(req.files)) 


outouts the multipart data :



[

"fieldname": "/storage/emulated/0/DCIM/.thumbnails/1535630435399.jpg",
"originalname": "jpeg",
"encoding": "binary",
"mimetype": "application/octet-stream",
"destination": "my_uploads/",
"original_name": "1533906137379-d2019-03-25-13-16-26-g15.jpg",
"path": "my_uploads/1533906137379-d2019-03-25-13-16-26-g15.jpg",
"size": 29955
,

"fieldname": "/storage/emulated/0/DCIM/.thumbnails/1535630444275.jpg",
"originalname": "jpeg",
"encoding": "binary",
"mimetype": "application/octet-stream",
"destination": "my_uploads/",
"original_name": "1533906137379-d2019-03-25-13-16-26-g15.jpg",
"path": "my_uploads/1533906137379-d2019-03-25-13-16-26-g15.jpg",
"size": 48901

]


As you can see at :



cb(null, req.body.original_name) 


I am trying to rename the file to original_name included in the multipart data sent.



How can I successfully carry this out?



Thank you all in advance.
