Is there a way to retrieve $httpProvider.defaults.xsrfCookieName within .factory?

Here's a question that might come from someone new to programming. I'm trying to avoid hard-coding the values for xsrfHeaderName and xsrfCookieName. Can anyone guide me on how to retrieve them from the $httpProvider?

.factory('XSRFInterceptor', function($cookies) {
  return {
    request: function(config) {
      config.headers[$httpProvider.defaults.xsrfHeaderName] =
      $cookies[$httpProvider.defaults.xsrfCookieName];
      return config;
    }
  }
})

.config(function($httpProvider) {
  $httpProvider.interceptors.push('XSRFInterceptor');
})

After experimenting with various methods, it seems like there's still more for me to learn about AngularJS. Any help in getting started would be greatly appreciated.

Answer №1

It's unlikely that you can actually inject $httpProvider into a factory. If you're looking to add properties to your headers, here is an alternative approach that I find effective:

app.factory('authInterceptor', ['$rootScope', '$q', '$window', 
  function ($rootScope, $q, $window) {
    return {
      request: function (config) {
        config.headers = config.headers || {};
        config.headers.Authorization = $cookies.Authorization;
        return config;
      }
    };
}]);

This method should work well for what you're attempting to achieve without the need for $httpProvider.

Answer №2

Starting from AngularJS 1.4.3, all that is required is a single line of code for dynamic injection:

.factory('XSRFInterceptor', function($cookies, $injector) {
  return {
    request: function(config) {
      var $http = $injector.get('$http');
      var xsrfToken = $cookies.get($http.defaults.xsrfCookieName);
      if (xsrfToken)
        config.headers[$http.defaults.xsrfHeaderName] = xsrfToken;
      return config;
    }
  }
}
