Utilizing the CORS protocol, the code below effectively sends a request and receives a response. The objective is to modify the content-type header from 'application/x-www-form-urlencoded' to 'application/json'. However, upon making this change, the request fails. Interestingly, when inspecting the request in the browser, it becomes apparent that instead of altering the content-type header, it has actually been entirely removed.
var servicesApp = angular.module('services', [])
.config(function($httpProvider){
/* Enable CORS */
$httpProvider.defaults.useXDomain = true;
delete $httpProvider.defaults.headers.common['X-Requested-With'];
})
.factory('model', function($http) {
var testJSON = '{"employees": [ {"firstName":"John", "lastName":"Doe"} ] }';
$http({
url: 'http://127.0.0.1:8081/controller/UIController',
method: "POST",
params: {"path" : "save"},
data: "message= " + testJSON,
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
}).success(function (data, status, headers, config) {
alert(data.ExampleForm[1]);
}).error(function (data, status, headers, config) {
alert(status);
});
