How to make a post request in angularjs?

Question

Angular

I make a request on click:

$scope.sentPhoto = function() {
      var data = {id_user: '31'};
      $http.post('http://site/api/v1/messages/index', data)
      .success(function(data)
      {
        console.log(data);
      });
    };

But the response from the server:

I don't understand what's the problem? There is definitely a method on the server.

Answer 1

The application and the target API are on different domains, so the browser uses a CORS policy to make requests, which instructs the browser to send an OPTIONS request before the POST request, which your server is not trained to handle.
