inject multiple values using provider to my service constructor - angular2

Question

How can inject multiple values to my service if I have constructor like this

@Injectable()
export class MyService implements OnInit {
    constructor(private http: Http, @Inject('name') @Optional() public name?: string) {            
}

and inside AppModule I tried following

...
providers: [
    SecurityService, providers:[
      {  provide: 'username', useValue: ''  },
      {  provide: 'http', useValue: Http  }
    ],
..

but I'm getting syntax error in line SecurityService, providers:[

Cannot find name providers

Just pass in the dependencies as an array (you don't need to destructure it):

...
providers: [
    SecurityService, 
    [
      {  provide: 'username', useValue: ''  },
      {  provide: 'http', useValue: Http  }
    ],
...

Or go ahead and destructure it for the sake of cleaner code:

...
providers: [
    SecurityService, 
    {  provide: 'username', useValue: ''  },
    {  provide: 'http', useValue: Http  }
...
