rc1 路由器 "No provider for Router"

Question

这是在@Shuhei 帮助我解决了 config.js 问题

之后出现的错误的跟进 post

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']);
  }

}

所有其他组件都像上面这样通过构造函数注入路由器。 当然有路由器.

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]

如果相同的代码在测试版中运行，是什么导致它在 RC1 路由器中不起作用？

更新：index.html

<html>
  <head>
    <base href="/">

    <title>My Tests</title>
    <meta name="viewport" content="width=device-width, initial-scale=1">

    <my-app>Loading...</my-app>
    <script>document.write('<base href="' + document.location + '" />');</script>

Answer 1

你需要提供路由器，像这样:

...
import { RouteConfig, ROUTER_DIRECTIVES, Router, ROUTER_PROVIDERS } from '@angular/router-deprecated';

@Component({
  selector: 'my-app', 
  templateUrl: 'app/appshell/app.component.html',
  styleUrls: ['app/appshell/app.component.css'],
  directives: [ROUTER_DIRECTIVES],
  providers: [ROUTER_PROVIDERS]
})
 ...

Answer 2

确保你的 index.html:

<script>document.write('<base href="' + document.location + '" />');</script>

Answer 3

从“@angular/router”
导入 ROUTER_DIRECTIVES、路由器和路由将@RouteConfig 替换为@Routes

这帮助我让它正常工作。 https://angular.io/docs/ts/latest/guide/router-deprecated.html

Answer 4

如果你想使用新的路由器，你应该改变你的代码：

import {Routes} from '@angular/router'

@Component({
  selector: 'my-app', 
  templateUrl: 'app/appshell/app.component.html',
  styleUrls: ['app/appshell/app.component.css'],
  directives: [ROUTER_DIRECTIVES],
})

@Routes([
    {
        path: '/app/apps/hero/...',
        component: HeroShellComponent,
    },
    { path: '/app/apps/testapp1', component: HomeComponent },
    { path: '/', redirectTo: ['Login'] },
    { path: '/home', component: HomeComponent },
    { path: '/login',  component: Login},   
])
export class AppComponent {}

对于angular路由器3.0.0-beta.1:

我遇到了类似的错误，我发现 WebStorm 为我自动导入 @angular/router-deprecated。从tutorial开始，应该是@angular/router.

app.component.ts:

import {ROUTER_DIRECTIVES} from "@angular/router";

rc1 路由器 "No provider for Router"

rc1 router "No provider for Router"
