AngularJS CORS example using

This is an example of a cross domain GET and POST request to a server with CORS headers enabled. It’s a very simple one field form that displays the echo’d response from httpbin. I chose httpbin since I knew it had CORS headers enabled, and seemed like a relatively simplistic tool to play around with.

As the code shows, GET requests are quite simple and look like a regular $http call. The heavy lifting is all done by the server

The POST request on the other hand is a little more complicated and requires some manipulation of the headers before the request itself.

First, we need to set the Content-Type to form-urlencoded to let the destination know we are posting form data:

$["Content-Type"] = "application/x-www-form-urlencoded";

Second, we need to delete a header called “Requested-With” that is sent along with AJAX requests:

delete $http.defaults.headers.common['X-Requested-With'];

Also, to stop this mistruth from spreading any farther: A lot of blog posts about Cross Domain posting with Angular will show you this code:

$http.defaults.useXDomain = true

It’s not a real config value, you don’t need it. Seriously. Try it with and later without it, you won’t see a difference (I think the dojo toolkit may require it, I’m not sure how it made it’s way into multiple AngularJS examples).
