angular - angular2 rc5 中没有路由器提供程序

Question

在 module.ts 中

    import { NgModule }      from '@angular/core';
    import { BrowserModule } from '@angular/platform-browser';
    import { Router } from '@angular/router'

    import { AppComponent }  from './app.component';

    @NgModule({
      imports: [
        BrowserModule
      ],
      declarations: [ 
        AppComponent
      ],
      bootstrap: [ AppComponent ]
    })
    export class AppModule { }

在组件中

import { Component } from '@angular/core';    
import { Router } from '@angular/router'; 

import { GlobalService } from './global.service';

@Component({
  selector: 'cwf',
  templateUrl: 'app/app.template.html'
})
export class AppComponent {
  public homeConfig = {};

    constructor(private _router:Router, private _globalService: GlobalService){}

我在构造函数中定义路由器以导航路线时出现错误。如果我评论构造函数行它工作正常。我需要在哪里添加提供商以及如何添加。

Answer 1

需要导入RouterModule

@NgModule({
  imports: [
    BrowserModule,
    RouterModule
  ],

或者像往常一样

const appRoutes: Routes = [
  {
    path: 'heroes',
    component: HeroesComponent
  }
];
export const routing: ModuleWithProviders = RouterModule.forRoot(appRoutes);

import { routing } from './app.routing';

@NgModule({
  imports: [
    BrowserModule,
    routing
  ],
