src/boot.ts

import {Component} from 'angular2/core';
import {ROUTER_PROVIDERS,RouteConfig, ROUTER_DIRECTIVES,LocationStrategy} from 'angular2/router';
import {bootstrap}        from 'angular2/platform/browser';

import{ComponentOne} from 'src/cone';
import{ComponentTwo} from 'src/ctwo';

@Component({
  selector: 'my-app',
  template: `
    <h1>Component Router</h1>
    <nav>
      <a [routerLink]="['ComponentOne']">One</a><hr/>
      <a [routerLink]="['ComponentTwo']">Two</a>
    </nav>
    <router-outlet></router-outlet>
  `,
  directives: [ROUTER_DIRECTIVES]
})
@RouteConfig([
  {path:'/component-one', name: 'ComponentOne', component: ComponentOne},
  {path:'/component-two', name: 'ComponentTwo', component: ComponentTwo}
])
export class AppComponent { }

    bootstrap(AppComponent, [
      ROUTER_PROVIDERS
]);

src/cone

 import {Component,View} from 'angular2/core';

 @Component({
    template: `
    <h1>first Component</h1>
    `
  })

  export class ComponentOne{
    constructor(){

      console.log("first component being called");
    }
  }

src/ctwo

 import {Component,View} from 'angular2/core';

 @Component({
    template: `
    <h1>Second Component</h1>
    `
  })

  export class ComponentTwo{
    constructor(){

      console.log("Second component being called");
    }
  }

请检查您的开发控制台。它给出了一个错误

EXCEPTION: Error during instantiation of LocationStrategy! (RouterLink -> Router -> Location -> LocationStrategy).BrowserDomAdapter.logError @ angular2.dev.js:23514 angular2.dev.js:23514 ORIGINAL EXCEPTION: No base href set. Please provide a value for the APP_BASE_HREF token or add a base element to the document.

此外，它不会将我重定向到目的地。我尝试添加 < base href="/" > 但它允许给出错误。

我希望链接正常工作。

Answer 1

将 <base href="/"> 添加到 <head> 元素或将 APP_BASE_HREF 添加到 bootstrap

bootstrap(AppComponent, [
  ROUTER_PROVIDERS, 
  // usually
  provide(APP_BASE_HREF, {useValue: '/'})
  // for Plunker
  // bind(APP_BASE_HREF).toValue(location.pathname)
]);

Nyks 编辑的回答：

在我的 plunker 中，我更新了以下部分，

import {Component,bind} from 'angular2/core';
import {ROUTER_PROVIDERS,RouteConfig, ROUTER_DIRECTIVES,APP_BASE_HREF,LocationStrategy,RouteParams,ROUTER_BINDINGS} from 'angular2/router';

export class AppComponent { }

    bootstrap(AppComponent, [
      ROUTER_PROVIDERS,bind(APP_BASE_HREF).toValue(location.pathname)
]);
