Multer upload is not a function
// Multer upload config
const fs = require('fs');
const path = require('path');
const multer = require('multer');
const storage = multer.diskStorage({
destination: function (req, file, cb) {
cb(null, '/tmp/')
},
filename: function (req, file, cb) {
const uniqueSuffix = Date.now() + '-' + Math.round(Math.random() * 1E9)
cb(null, file.fieldname + '-' + uniqueSuffix + path.extname(file.originalname))
}
})
const upload = multer({storage: storage});
app.post('/uploadPhoto', (req, res, next) => {
upload.single('filename_here')(req, res, function (err) {
if (err) {
// A Multer error occurred when uploading.
res.json({msg: err.message})
} else {
// Everything went fine.
// req.file
// {
// fieldname: 'filename_here',
// originalname: 'nhancv_dep_trai.png',
// encoding: '7bit',
// mimetype: 'image/png',
// destination: '/tmp/',
// filename: 'filename_here-1607694392023-220481630',
// path: '/tmp/filename_here-1607694392023-220481630',
// size: 5907
// }
const file = req.file;
console.log(file);
// Delete tmp
try {
// fs.unlinkSync(file.path);
} catch (e) {
// Ignore
console.error(e);
}
res.json({msg: 'ok'});
}
});
})
Test
curl --location --request POST '<host>:<port>/uploadPhoto' \
--form 'filename_here=@"/Users/nhancv/Desktop/nhancv_dep_trai.png"'
As @Aabid told in The comments you will not need to use both, the multer middleware and upload in the controller.
You can use:
app.post('/editPhoto', upload.single('avatar'), (req, res, next) => {
// here in the req.file you will have the uploaded avatar file
})
Or you can use:
app.post('/editPhoto', (req, res, next) => {
upload(req, res, function (err) {
if (err) {
// This is a good practice when you want to handle your errors differently
return
}
// Everything went fine
})
})
So you use one of the 2 methods, not both at the same time.
