Can the Angular Injector inject a method?


Can the Angular Injector inject a method?

around this issue Actually - there is a way to do this, by using .constant or .value. (From what I understand, .constant can be used in a config block, while value cannot be.) You'd do something like the following:
code :
angular.module('myApp', [])
    .value('storage', window.localStorage);

Angular $injector vs inject

Angular $injector vs inject

Hope this helps If I am not mistaken, inject uses $injector to do the job, so it is the same thing at the end.
The advantage of inject is that is more visual, easy and less code to write. It works like the normal angular DI, just adding what you need to inject via params.

I wish this help you Due to John Papa - 10 AngularJS Patterns presentation advices I try to implement additional functionality to exception handling: , The issue is that even if you do,
code :
function ExceptionHandlerService($window, $injector){
    var $modal = $injector.get('$modal')
}
 function ExceptionHandlerService($window, $injector){

        function _getModal(){
           //You can afford to do this everytme as service is a singleton and
           //the IOC container will have this instance always once instantiated as it will just act asa getter.
           return $injector.get('$modal');
        }

        function logStuff(){
            _getModal().modal(....
        }
    }

With these it helps Edit: answer is outdated, since rc5 release you should use NgModule for this.
Just use addProvider method of UpgradeAdapter.
code :
import { UpgradeAdapter } from '@angular/upgrade';
import { YourService} from "./YourService";

const upgradeAdapter = new UpgradeAdapter();
upgradeAdapter.addProvider(YourService);
@Component({
    selector: 'cmp-selector',
    template: '...',
    // Don't specify YourService again or you will receive another instance
    // providers: [YourService] 
})
export class SomeComponent {
    constructor(private service: YourService) {}
}
Why can't I inject a service into Angular factory/injector?

this will help It looks like you have a circular dependency in your interceptor. You're attempting to inject a service that is using $http while at the same time attempting to configure the $httpProvider.
One solution would be to manually inject the authService inside the request property of the interceptor.
code :
app.factory('authInjector', ['$injector', function($injector) {

  var authInjector = {
    request: function (config) {
      var AuthService = $injector.get('AuthService');
      // Do whatever you need to do with AuthService
      config.headers['x-session-token'] = 'test'; 
      return config;
    }
  };
  return authInjector;
}]);
