I am creating a React and Node application, and at the moment I need to upload a PDF file, the code works well, but I was wondering how to use front variables to create the file name by multer.
The code...
Front:
const handleSubmit = async (e) => {
const dado = new FormData()
const year = data.split("/")
const dd = year[0];
const mm = year[1];
const aaaa = year[2];
dado.append('file', file)
dado.append('uni', uni)
dado.append('dd', dd)
dado.append('mm', mm)
dado.append('aaaa', aaaa)
console.log(dado)
axios.post("http://localhost:8080/api/comprebem/file", dado, {
})
.then(res => {
console.log(res.statusText)
})
}
Back:
const storage = multer.diskStorage({
destination:"../login/public/comprebem/ibama/",
filename: function (req, file, cb) {
console.log(file);
cb(null, `unidade${"req['uni']"}_data${file.originalname}` )
}
})
const upload = multer({ storage: storage }).single('file')
app.post('/api/comprebem/file',function(req, res) {
upload(req, res, function (err) {
if (err instanceof multer.MulterError) {
return res.status(500).json(err)
} else if (err) {
return res.status(500).json(err)
}
return res.status(200).send(req.file)
})
});
