【问题描述】:
这是@Shuhei 帮助我解决config.js 问题angular 2 rc router angular2-polyfills.js:349 Error 后出现的错误的后续帖子@
这是我的 app.component.ts
import { Component,provide } from '@angular/core';
import { RouteConfig, ROUTER_DIRECTIVES,Router } from '@angular/router-deprecated';
import { HeroShellComponent } from '../apps/hero/hero-shell.component';
import {HomeComponent} from '../home/home.component';
import {Login} from '../login/auth.component';
import {Authentication} from '../login/auth.service';
import {isLoggedin} from '../login/auth.isLoggedin';
@Component({
selector: 'my-app',
templateUrl: 'app/appshell/app.component.html',
styleUrls: ['app/appshell/app.component.css'],
directives: [ROUTER_DIRECTIVES],
})
@RouteConfig([
{
path: '/app/apps/hero/...',
name: 'Hero Sample',
component: HeroShellComponent,
},
{ path: '/app/apps/testapp1', name: 'Testapp1', component: HomeComponent },
{ path: '/', redirectTo: ['Login'] },
{ path: '/home', name: 'Home', component: HomeComponent },
{ path: '/login', name: 'Login', component: Login, useAsDefault: true },
])
export class AppComponent {
title = 'Apps';
constructor(public _auth: Authentication,
public router: Router
) {}
onLogout() {
this._auth.logout();
this.router.navigate(['/Login']);
}
}
所有其他组件通过像上面这样的构造函数注入路由器。 当然提供了路由器。
path: '/app/apps/hero/...'
用于子路由器重定向。
我得到的错误是
browser_adapter.ts:78 EXCEPTION: Error:
Uncaught (in promise): EXCEPTION: Error in :0:0
ORIGINAL EXCEPTION: No provider for Router!.
ORIGINAL STACKTRACE: Error: DI Exception
at NoProviderError.BaseException [as constructor] (npmcdn.com/@angular/core@2.0.0-rc.1/src/facade/…)
at NoProviderError.AbstractProviderError [as constructor]
如果相同的代码在 Beta 版中可以正常工作,那么是什么导致它在 RC1 路由器弃用的情况下无法正常工作?

这个错误真的发生在
AppComponent吗?您介意在 plunker 上创建一个 MCV 示例,以便人们可以修改它。 stackoverflow.com/help/mcve
