data sent as application/json

[DanRamGim]

how can I achieve to send my file in ng-file-upload as a application/json to be able to receive the file in my REST server ?

Thank you in advance

Set the content-type in the header section. Read the documentation and search for 'type'

For anybody still using this ( *sadpanda* for legacy apps):

Upload.http({
  url: '/api/uploadImage',
  data: json,
  headers : {
    'Content-Type': 'application/json'
  },
});
