I am using the following to upload files to a directory via Multer. It works great, but I need to perform some actions after upload that require the name of the file I just posted to the "upload" directory. How do I get the name of the file I just posted?
// Multer storage options
var storage = multer.diskStorage({
destination: function(req, file, cb) {
cb(null, 'upload/');
},
filename: function(req, file, cb) {
cb(null, file.originalname + '-' + Date.now() + '.pdf');
}
});
var upload = multer({ storage: storage });
app.post('/multer', upload.single('file'), function(req, res) {
// Need full filename created here
});
var express=require("express");
var app=express();
var multer=require("multer");
var upload=multer({dest:"uploads/"});
app.post("/multer", upload.single("file"), function(req,res){
console.log(req.file.filename);
});
request.file
gives the following stats, from which you would just need to pick request.file.originalname
or request.file.filename
to get the new filename created by nodejs app.
{
fieldname: 'songUpload',
originalname: '04. Stairway To Heaven - Led Zeppelin.mp3',
encoding: '7bit',
mimetype: 'audio/mp3',
destination: './uploads',
filename: 'songUpload-1476677312011',
path: 'uploads/songUpload-1476677312011',
size: 14058414
}
Eg, in nodejs express mvc app with ecma-6,
var Express = require('express');
var app = Express();
var multipartUpload = Multer({storage: Multer.diskStorage({
destination: function (req, file, callback) { callback(null, './uploads');},
filename: function (req, file, callback) { callback(null, file.fieldname + '-' + Date.now());}})
}).single('songUpload');
app.post('/artists', multipartUpload, (req, resp) => {
val originalFileName = req.file.originalname
console.log(originalFileName)
}
Accessing uploaded files data differs in Multer, depending whether you are uploading single or multiple files. Access data like so:
uploading single file:
req.file
uploading multiple files:
req.files
I found the answer on github, you have access to it in
res.req.file.filename
See there for more informations https://github.com/expressjs/multer/issues/302
app.post('/multer', upload.single('file'), function(req, res) {
// Need full filename created here
const file = req.file
if (!file) {
const error = new Error('Please upload a file')
error.httpStatusCode = 400
return next(error)
}
res.send(file) #Here
});
You need recover file from this line
res.send(file)
using file.filename This output sample
{
"fieldname": "myFile",
"originalname": "isc te esta esperando.jpg",
"encoding": "7bit",
"mimetype": "image/jpeg",
"destination": "uploads",
"filename": "myFile-1602293858948.eaf",
"path": "uploads/myFile-1602293858948.eaf",
"size": 297720
}
using request.file.filename
fieldname Field name specified in the form
originalname Name of the file on the user's computer
encoding Encoding type of the file
mimetype Mime type of the file
size Size of the file in bytes
