Node js / Angular js - CAUTION: Provisional headers are shown [duplicate]

Answer 1

personaly I use this "reset" method in angular:

app.config(['$httpProvider', function ($httpProvider) {
  //Reset headers to avoid OPTIONS request (aka preflight)
  $httpProvider.defaults.headers.common = {};
  $httpProvider.defaults.headers.post = {};
  $httpProvider.defaults.headers.put = {};
  $httpProvider.defaults.headers.patch = {};
}]);
