"angularjs post fails: response for preflight has invalid http status code 404" Answer’s

EDIT:

It's been years, but I feel obliged to comment on this further. Now I actually am a developer. Requests to your back-end are usually authenticated with a token which your frameworks will pick up and handle; and this is what was missing. I'm actually not sure how this solution worked at all.

ORIGINAL:

Ok so here's how I figured this out. It all has to do with CORS policy. Before the POST request, Chrome was doing a preflight OPTIONS request, which should be handled and acknowledged by the server prior to the actual request. Now this is really not what I wanted for such a simple server. Hence, resetting the headers client side prevents the preflight:

app.config(function ($httpProvider) {
  $httpProvider.defaults.headers.common = {};
  $httpProvider.defaults.headers.post = {};
  $httpProvider.defaults.headers.put = {};
  $httpProvider.defaults.headers.patch = {};
});

The browser will now send a POST directly. Hope this helps a lot of folks out there... My real problem was not understanding CORS enough.

Kudos to this answer for showing me the way.
