Anda perlu mengubah kode sudut Anda untuk mengirim info tambahan dalam data permintaan
Upload.upload({
url: 'http://localhost:3000/upload', //webAPI exposed to upload the file
data:{file:file, name:vm.name, email:vm.email} //pass file as data, should be user ng-model
})
Kemudian di kode backend Anda, Anda dapat mereferensikannya di badan permintaan
req.body.name
req.body.email
