将angularjs服务注入Angular [英] Inject angularjs service into Angular

问题描述

我正在尝试将 $ log 服务用于角度2，根据我的阅读，您需要执行以下步骤：

I'm trying to use $log service into an angular 2, According to what I read you need the following steps:

1. 创建一个包含要注入的服务的模块。


2. 调用UpgradeAdapter的upgradeNg1Provider方法。

所以，我做了以下

  var initInjector = angular.injector(['ng']);
  var $log = initInjector.get('$log');
  angular.module('Services1', [])
    .service('$log', [$log]);
  upgradeAdapter.upgradeNg1Provider('$log');

然后我创建一个角度2组件，如下所示

Then I create an angular 2 component as the following

    @Component({   selector: "ion-app",   template:"<p>Test</p>" })
    @Injectable()
    export class HelloIonicPage {
      message: string;
      constructor( @Inject('$log') $log) {
        this.message = "Hi";
      }
    }

但是当我运行应用程序时，它给了我以下内容错误：

But when I run the application it gives me the following error:

ORIGINAL例外：$ log没有提供者！

ORIGINAL EXCEPTION: No provider for $log!

另外，我尝试 bootstrap 使用 upgradeAdapter ：

  upgradeAdapter.bootstrap(document.documentElement, ['Services1'])

但这也不起作用。
请注意我使用的是Ionic 2框架，上面的代码写在里面

But that didn't work also. Please note that I'm using Ionic 2 framework and the above code is written inside

    this.platform.ready().then(() => { 
            //The code is going here
});

推荐答案

您需要将服务注册为提供者。以下是我如何将angular1 $状态注入angular 2应用程序：

You need to register service as provider. Here is how I inject angular1 $state to angular 2 application:

@NgModule({
  providers: [
    {
       provide: '$state', 
       useFactory: ($injector: any) => $injector.get('$state'), 
       deps: ['$injector']
    }
  ]
})

然后在注射地点：

@Injectable()
export class RestService {
  constructor(@Inject('$state') $state: any) {
    $state.go('...');
  }
}
