Exploring AngularJS's capabilities with Cross Domain POST requests

One query I have concerning CORS requests that include the HTTP Authorization header:

I've noticed that the web browser doesn't seem to send the Authorization header with POST requests, is there a workaround for this?

Below is the Angular code I am using:

var app = angular.module('app', [])
    .config(['$httpProvider', function($httpProvider) {
        $httpProvider.defaults.useXDomain = true;
        delete $httpProvider.defaults.headers.common['X-Requested-With'];
    }]);

    app.controller('ctrl', function ($scope, $http) {
        $scope.insert = function () {

            $http.post('http://my.api.com/Insert',
                {
                    headers: {
                        'Authorization': 'Basic dGVzdDp0ZXN0',
                        'Content-Type': 'application/x-www-form-urlencoded'
                    },
                    data: {
                        'Code': 'test data'
                    },
                    withCredentials: true
                });
        };
    });

On the server side, I have the following in my web.config file:

<httpProtocol >
  <customHeaders>
    <add name="Access-Control-Allow-Origin" value="*" />
    <add name="Access-Control-Allow-Headers" value="Cache-Control, Pragma, Origin, Authorization, Content-Type, X-Requested-With" />
    <add name="Access-Control-Allow-Methods" value="GET,POST,PUT,DELETE,OPTIONS" />
    <add name="Access-Control-Allow-Credentials" value="true" />
  </customHeaders>
</httpProtocol>

Answer №1

Your usage of the $http.post function is incorrect. The second parameter should be the data that needs to be sent to the server. You cannot set headers in this manner. In this scenario, the entire object will be sent as a JSON payload

Here's a revised version:

$http({
       url:'http://my.api.com/Insert',
       method:"POST",
       headers: {
                  'Authorization': 'Basic dGVzdDp0ZXN0',
                  'Content-Type': 'application/x-www-form-urlencoded'
       },
       data: {
              'Code': 'test data'
       }
  });

Answer №2

The withCredentials property is a {boolean} that determines whether to set the withCredentials flag on the XHR object. To learn more about requests with credentials, refer to the documentation.
