提供AngularJS 2

Question

我试图使用提供bootsrap但不工作，这是我的代码：

import { NgModule, provide }  from '@angular/core'; 
import { BrowserModule } from '@angular/platform-browser'; 
import { AppComponent } from './app.component'; 
import { HomeComponent } from './home/home.component'; 
import {AboutComponent} from './about/about.component'; 
import {LoginComponent} from './account/login/login.component'; 
import { FormsModule } from '@angular/forms'; 
import { HttpModule,BaseRequestOptions } from '@angular/http'; 
import { AuthenticationService} from './account/login/login.service'; 
import appRoutes from './app.router'; 

/** 
* Extending BaseRequestOptions to inject common headers to all requests. 
*/ 
class CustomRequestOptions extends BaseRequestOptions { 
    constructor() { 
     super(); 
     this.headers.append('Authorization', 'my-token'); 
     this.headers.append('foo', 'bar'); 
    } 
} 

@NgModule({ 
    imports: [BrowserModule, appRoutes, FormsModule, 
    HttpModule], 
    declarations: [AppComponent, HomeComponent, AboutComponent, LoginComponent], 
    bootstrap: [AppComponent, 
    provide({useClass: CustomRequestOptions}) ], 
    providers: [ 
    AuthenticationService 
    ] 

}) 

export class AppModule { }

最后一个版本上有NgModule没有财产，你可以简单地传递到provide呼叫的结果，你需要provide为你提供一个存储像这样的一部分...

providers: [ 
    AuthenticationService, 
    { provide: CustomRequestOptions, useClass: CustomRequestOptions } 
]
