[angularjs] How to create an AngularJS HTTP Interceptor

angularjs-interceptor.js

// Intercepting HTTP calls with AngularJS.
angular.module('MyApp', [])
.config(function ($provide, $httpProvider) {
  
  // Intercept http calls.
  $provide.factory('MyHttpInterceptor', function ($q) {
    return {
      // On request success
      request: function (config) {
        // console.log(config); // Contains the data about the request before it is sent.

        // Return the config or wrap it in a promise if blank.
        return config || $q.when(config);
      },

      // On request failure
      requestError: function (rejection) {
        // console.log(rejection); // Contains the data about the error on the request.
        
        // Return the promise rejection.
        return $q.reject(rejection);
      },

      // On response success
      response: function (response) {
        // console.log(response); // Contains the data from the response.
        
        // Return the response or promise.
        return response || $q.when(response);
      },

      // On response failture
      responseError: function (rejection) {
        // console.log(rejection); // Contains the data about the error.
        
        // Return the promise rejection.
        return $q.reject(rejection);
      }
    };
  });

  // Add the interceptor to the $httpProvider.
  $httpProvider.interceptors.push('LoggingHttpInterceptor');

});

@gergely-kovacs It doesn't work, you need to change it to $httpProvider.interceptors.push('MyHttpInterceptor'); otherwise you get Error: [$injector:unpr] Unknown provider: LoggingHttpInterceptorProvider.

@edysegura This is a good example, thanks.
