Personalized AJAX characteristic inside AngularJs Service

Let's consider a very simple scenario:

Here is the code snippet:

$.ajax({
    type: "GET/POST",
    url: 'http://somewhere.net/',
    data: data,
    beforeSend: '', // custom property
}).done().fail();

My main goal is to find a proper way to modify the beforeSend function within an Angular factory service. Here is an example of what I currently have in my code:

myApp.factory('GetBalance', ['$resource', function ($resource) {
    return $resource('/Service/GetBalance', {}, {
        query: { method: 'GET', params: {}, }, isArray: true,
    });
}]);

In this case, I am utilizing AngularJs service API, however, the documentation available is not very clear on how I can achieve my desired modification.

Answer №1

To include custom headers with your request, follow these steps.

myApp.factory('GetBalance', ['$resource', function ($resource) {
    return $resource('/Service/GetBalance', {}, {
        query: { method: 'GET', params: {}, headers: { 'Authorization': 'Bearer token' } }, isArray: true,
    });
}]);

Answer №2

If you're curious about requestInterceptors, you may want to explore the addFullRequestInterceptor method that offers a range of parameters:

This method allows you to return an object with any combination of the following properties:

  • headers: Includes the headers to be sent
  • params: Contains the request parameters to be sent
  • element: Describes the element to be sent
  • httpConfig: Specifies the httpConfig to be called with

Answer №3

Despite following the recommendations offered by @Thalaivar in the Angular documentation, the suggested solution did not prove effective for my specific scenario.

Therefore, I present an alternate approach that successfully resolved the issue:

myApp.config(['$provide', '$httpProvider', function ($provide, $httpProvider) {
    // Setting up request headers
    $httpProvider.defaults.headers.common['modId'] = 1;     // dynamic parameter
    $httpProvider.defaults.headers.common['pageId'] = 2;    // dynamic parameter
    $httpProvider.defaults.headers.common['token'] = 'xyz'; // dynamic parameter
    $httpProvider.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';
});

Although the header values appear hard-coded in this example, in reality, they are retrieved dynamically as per the distinct requirements of each page.

Furthermore, it is important to note that if you are utilizing $http based services, this step may not be necessary.
